In the house - a great thing in warm time of the year. But with the onset of cold weather, the owners suddenly notice that the corners of the extension are frozen and blackened, the wallpaper is damp, and in general the veranda can no longer cope with retaining the cold from the street. It's time to think about how to insulate the terrace next winter, especially if this part of the premises is planned for living.
A summer veranda in the house is a great thing in the warm season
This is a big matter and requires an integrated approach. To put it simply, you will have to insulate the veranda with your own hands from bottom to top, from the subfloor to the roof.
To have everything at hand, let's prepare:
To insulate the veranda you will need a hammer, nails, putty with spatulas, masking or construction tape, tape measure, hacksaw, screws and nails, pencil
Materials will have to be purchased as stages of work are completed.
Even in normal warm apartment The lion's share of heat evaporates if it comes through from the windows. On the veranda, even more so, the windows cause huge losses. If you have old ones installed wooden windows, don’t skimp on new double-glazed windows, they’re worth it. If it is not possible to replace the windows, you should seal the cracks in them as much as possible. Ready-made adhesive strips of foam rubber are suitable for this or, at worst, masking tape, you can use it to seal your windows and survive the winter. In old windows, you need to double-check the condition of the outer glazing beads, replace rotten or broken ones, put the glass on sealant and press it with new glazing beads.
Ready-made adhesive strips of foam rubber are suitable for insulating windows.
The doors should also be insulated first, by laying a special insulating strip of rubber or adhesive foam rubber along the diameter.
It is very important to insulate the ceiling from the roof of the house. Good insulation will help not only cold winter, but will also save you from the heat in summer time. It can usually be done cheaply and simply. The easiest way is to plaster the ceiling, because plaster reduces the moisture capacity of the surface and creates an additional layer of insulation.
When choosing thermal insulators, you need to give preference to non-toxic materials. Cardboard is effective, but it has bad qualities- it has excellent flammability and absorbs moisture.
Vermiculite and other mineral wool have good insulating properties. These insulators are safe to use, do not burn, are affordable and are always available in hardware stores. It is convenient to use this insulation in the form of slabs, but first you should lay a layer of vapor barrier in the form of roofing felt.
Good insulation will help not only in the cold winter, but also save you from the heat in the summer.
One of the best ways Ceiling insulation is called laying foamed foil polymer; it is capable of not only retaining heat, but also not allowing moisture to pass through.
Layers of insulation are laid between the ceilings. Among the most exotic ways to keep heat from being lost through the ceiling are plastic bottles. If you collect them, tie them tightly together and lay them in the form of mats on top of the ceiling, they will become a kind of cold traps and create a barrier to heat loss.
When talking about floors, we mean insulation from the foundation side - insulation of the space near the ground, insulation of the foundation and the floor itself.
Step 1. Expanded clay-earth option.
Traditionally, when making a foundation for a terrace, home owners continue the line of the old foundation. And it, as a rule, is brick or concrete. Having excellent strength, these materials suffer from one drawback - they are cold. Both the cement base and the concrete slab draw heat from the room. Thus, losses through the foundation constitute a fifth of all heat losses.
Isolate the veranda from the cold underground in wooden house You can use a layer of earth or expanded clay. This is usually done when building a terrace - along the line of the strip base, the middle is covered with insulation. In this case, the land is free of charge, but does not have very high thermal insulation properties. Expanded clay is expensive, but it has good properties keep warm.
You can isolate the veranda from the cold underground floor in a wooden house with a layer of earth or expanded clay
Step 2. “Warm” the foundation.
During cold winters, the ground near the foundation freezes, causing it to shrink and expand when it thaws. So the foundation “plays” several times during the winter, which leads to the formation of cracks and destruction of the foundation in the house. To avoid this, you need to cut off the foundation from contact with the outer layer of the earth. To do this, the foundation must first be dug to the very bottom. Then coat with bitumen or special bitumen-polymer mastic. Let it dry and stick sheets of polystyrene foam or other polystyrene-based heat insulator on top. Cover the foundation with polystyrene sheets to the very top, including the base part. For the work, polyurethane glue is used, and the sheets must be glued very carefully, pressing them along the edges, so that the so-called cold bridges are not preserved and there is no access of moisture to the base of the house.
IN Lately in the materials market for construction work and repairs, many types of sprayed insulation have appeared. This material is a polyurethane foam mass in cylinders, which gives a very good insulation effect. It is applied to the wall, and after spraying, the foam hardens after some time, turning into a dense and durable crust. It has one minus - the price.
Step 3. Insulate the floors.
In private households, there is an eternal problem - it blows from the underground, and it’s cold on your feet. You can't do without insulation. Usually the problem is solved with a gasket heated floors under the screed - electric or water. In an unheated extension, you have to solve the problem in a different way:
The most big square contact with cold - near the walls. You can insulate the veranda from the outside and inside. Insulating the veranda from the inside is done if the outside of the building is decorated with expensive, high-quality materials that would be a shame to open.
Insulation of the veranda from the inside is done if the outside of the building is decorated with expensive high-quality materials that would be a shame to open
How to insulate a veranda from the inside:
If it is possible to insulate the walls from the street, then it is better to do so. Firstly, it will help save previously done interior decoration. Secondly, it is more beneficial in terms of heat conservation. External materials such as brick and concrete not only do not heat up, but under certain conditions are also capable of taking heat from interior space. Therefore, the task is to insulate more thermally conductive materials, such as brick, concrete, with less thermally conductive ones, such as, for example, mineral wool, basalt or cellulose insulation polystyrene foam or other polystyrenes.
You can insulate walls from the street like this:
Modern technologies for the production of building materials offer new developments for insulation, which may have their own installation conditions. Some of them, including ventilated facade technologies, allow for insulation work even in the cold season, since they do not involve the use of adhesives.
In the diagrams below you can see examples of how insulation of wooden, as well as brick and concrete walls is carried out.
If you are working with polystyrene foam, then you should start laying by installing a small bottom shelf, and glue the first sheet onto it. Next, the sheets are glued with an adhesive and applied one by one to the wall under level control. When the first layer has dried, the next one is installed, and the joints of the slabs should be shifted by half.
In the corners of the wall and near the windows, foam plates are additionally fixed metal corner in all other sheets, the sheets are also fastened with anchors in the form of “mushrooms” - in the center and at the corners of the sheets. The joints of the slabs are fixed with reinforcing tape for plastering work. Next, you need to attach the reinforcing mesh to the slabs and you can begin plastering work.
Important! Expanded polystyrene is good for insulating brick and concrete walls, however an important condition quality of work will be pre-drying the wall. This will avoid the accumulation of moisture under the insulating layer. After all, as you know, polystyrene foam does not have good vapor permeability, so after you cover the walls with insulation, it will be difficult to remove dampness from under the slabs.
Insulation with basalt, mineral wool or cellulose materials is carried out over lathing, which is mounted with wooden slats. Required condition- the insulation sheets should be a little larger, literally a couple of centimeters, than the sheathing cells. This will make the insulation tight, without gaps. Anchors are installed at the corners of the cells for better fastening of the insulation. On uneven wall It is better to use two-layer insulation. In this case, a soft layer needs to be mounted to the wall, which will hide the unevenness. You can install a reinforcing mesh on top of the insulation layer and do plastering work (when using, for example, mineral wool). Or make a three-layer ventilated facade: fixing a film over the insulation as a wind barrier, fill it with horizontal lathing and then cover the walls with siding, clapboard, or cover it with brick.
Below is a diagram of insulation with mineral wool slabs.
Scheme of insulating the veranda with mineral wool slabs
Many summer residents or owners country houses Wondering how to insulate a cold veranda? To increase living space, many resort to insulating this part of the house, which results in additional meters. You can sit there in winter with friends or family over a cup of tea. But for this it is necessary to carry out technological insulation work. What is the meaning of this work and how to properly insulate the veranda will become clear after reading this article to the end.
Insulating the veranda of a country house can be done at any time, because there are several ways. If, of course, you chose outdoor version- it is best to carry out work in the warm season. Some materials can only be used in positive temperatures. External insulation is good because the dew point is located on the street side, without being sunk into the plane of the wall.
And if it’s cold or chilly outside, then it’s better to choose internal method insulation. Thus, the technology laid down by the manufacturers of insulation products will not be violated.
Most reliable method insulation is frame. Because this design turns out to be more reliable and durable than, say, gluing polystyrene foam to the wall. In addition, thanks to the frame, absolutely any type of insulating material can be laid on the walls. The following can act as insulation:
And most importantly, you can then hide all this under any covering, be it lining, drywall or some other finishing material.
The task is to cut off the entry of cold into the room. You need to place the frame on the ceiling, walls and floor. You can start with the walls, the material for the frame is wood, which is environmentally friendly, simple and easy to use. You can design the easiest option. For this wooden blocks are installed horizontally along the entire plane of the wall, with a step of 50–60 centimeters from each other.
The choice of beam size depends on the thickness of the insulation and the number of layers. For example, if we consider one layer, then the wooden beam for the sheathing must be 50*50 mm, since the insulation itself has a thickness of 50 millimeters.
It is important to note that the insulation cannot be crushed because of this it may lose its properties. It is necessary to strictly adhere to the thickness of the insulating product. It’s not for nothing that the manufacturer has specified an indefinite size for resistance to cold. Energy consumption for heating may directly depend on the insulation of the veranda from the inside.
If there is an even angle under the ceiling, then you can lay the first beam in this place. After this, measure 50 cm from the bottom edge of the beam with a tape measure (unless, of course, the min wool is also 50 cm) and mark with a pencil where the next beam will go. We fasten part of the frame on the marked line using a screwdriver and self-tapping screws. And so on to the very bottom.
If the last section doesn't fit into the step size, it's okay. With a larger pitch of structures, a strip of insulation is added. At a smaller distance, in contrast to the standard step, the material is cut off. It is important that the bottom sheathing is in place to attach the sheathing.
It must be remembered that all bars must be set strictly at level. It is better to make the cells themselves a little smaller by 2-3 millimeters so that the basalt slabs stand upright. Well, everything is ready and you can lay the insulation.
Insulation process
Mount basalt slab 60 cm wide and 50 mm thick is not difficult. It is inserted entirely into the formed cells, and the excess is cut off. It is important to remember that the mineral wool should fit tightly with a slight spacer between the frame. There should be no gaps or holes left.
Now all that remains is to stretch the vapor barrier with an overlap of 10 cm over each other along the entire wall. The protective layer is attached to the frame using staples and a stapler. This event is necessary to protect the insulation from moisture. All joints, for greater tightness, are taped with special tape.
Finishing after insulation
The frame can be sheathed with any finishing material, which will suit your taste. Perfect for:
You can also use drywall. This will require preliminary installation of the frame with a certain step. As insulation will do 60 cm basalt slabs. Each material is attached according to the rules established by the manufacturer.
Before insulating the floor on the veranda, you need to prepare the following materials:
Wooden logs are treated with protective emulsions and attached to the floor. Fastening occurs using dowels, nails or self-tapping screws, depending on the type of floor. The step that will be needed for comfortable laying of polystyrene foam is 50 cm. After all the slabs are laid, it is necessary to check everything for the presence of cracks. If any are found, they are foamed with polyurethane foam.
You can move on to the stage of insulating the upper part of the room. Everyone knows that warm air concentrated at the top of the room. But this air cushion does not protect against drafts. Therefore, it is also advisable to insulate the ceiling part of the veranda room.
Many people believe that insulating the ceiling is quite a difficult job. In fact, installing insulation is not so difficult. You just need to choose the right technology. The choice of insulation will also depend on it. There are several approaches to this event:
Attic insulation is often done during construction. But it can be done later. This option is good because it doesn’t take internal space premises. The insulation is placed in the cells of the rafter system and covered with a vapor barrier.
But we will focus on internal ceiling insulation and consider it in more detail. If you have a high-quality roof, you can do a little insulation. For this we use 30*30 mm timber. Accordingly, insulation of the same thickness is laid in the space between the sheathing.
For a simply covered veranda roof, the insulation of the ceiling must be done thoroughly. This uses:
A frame is created in increments of 50–60 cm, into which any insulation is placed. This can be mineral wool, or denser polystyrene foam. To prevent the material from falling out under the force of gravity, a vapor barrier is secured until the finishing is completed.
You can also place the insulation in boxes with already installed ceiling trim. In this case, a layer of vapor barrier fabric is partially installed. The cladding material is attached on top of it. Insulating material is inserted into the space formed between the finishing and the rough ceiling.
Based on this article, it is clear that insulation with your own hands is possible and completely uncomplicated. If you decide to do external insulation of the walls of the veranda, then you need to take into account weather. It should not be windy or humid outside.
Installing the frame is no different from internal version. The timber can be mounted vertically or horizontally, it all depends on your desire and future cladding. There are, of course, several important conditions:
The main heat loss of any room occurs through windows and doors. In order to reduce costs, it is necessary to carefully approach the insulation of the junction of these elements.
Installing single glazed windows can significantly weaken the temperature balance of the veranda. Large volumes of glazing will also reduce thermal indicators premises. It’s better not to save money, but to install double or triple glazed windows.
The junctions between window blocks and walls are foamed assembly adhesive. Often, strip thermal insulation is used to increase the thermal effect.
It is also equally important to insulate the door. You can upholster it with felt or other similar material inside and out. Along the perimeter door frame you need to install rubber self-adhesive seals. It is advisable to install a second door to create an air gap.
As you can see, there is nothing complicated in all stages of the work. It is possible to produce all types of insulation yourself, thereby saving significant money on craftsmen.
In conclusion, significant savings should be noted. If you take the insulation of a room seriously and create something like a “thermos” out of it, you can reduce heating costs. To create a comfortable temperature it will be enough electric convector switched on at low power. But this is only possible if you select high-quality materials and follow the technology for their installation.
The veranda is an excellent place where you can have tea with family or friends, or just relax. IN hot weather it turns into the most popular area of the house, but when the temperature drops, the situation changes dramatically, because no one wants to sit in the cold.
But there is a way out of this situation. You just need to find out how to insulate the veranda and carry out the necessary processes. Properly performed insulation will help preserve established amenities and prevent the occurrence of black spots that form when the temperature drops.
The number of materials that can be used for insulation is simply enormous. But among them we can single out those that are given the greatest preference among consumers, because they have proven themselves to be excellent with their positive qualities.
Mineral wool is used for insulation of floors, ceilings, walls and ceilings. There is a huge assortment on the market that allows you to choose the perfect suitable look from various manufacturers. It is suitable both for covering the veranda and for complete insulation of the house.
The product's characteristics are very similar to polystyrene foam. It is highly durable and can be easily finished. Perfectly suited as insulation for a terrace.
This product is distributed in 3 different types: flexible slabs, rough panels and in inflatable form. The advantages include easy installation and low weight. Disadvantages: poor tolerance mechanical influences and significantly high cost.
Polystyrene foam and mineral wool are the most popular among consumers. They are profitable and excellent insulation for the veranda, which have a number of positive properties and allow you to save a decent amount of money.
Insulating a veranda with your own hands is quite simple if you thoroughly understand all the stages of the work being carried out. Basically, the terrace is built on the same foundation as the house. Typically these are concrete slabs or a monolithically poured concrete base. IN winter period 20% of the heat leaks through it, so before insulating the veranda, you need to insulate the foundation of the structure. This process is carried out without any particular difficulties. Polystyrene foam boards need to be glued to the surface of the base.
First of all, when insulating a terrace, the floor is insulated. Some people do not attach much importance to this process, limiting themselves only to the treatment of ceilings and walls, believing that it is not necessary to insulate floor surfaces and are deeply mistaken. In wooden verandas the floor is often laid as follows: on the ground or concrete base logs are laid on which boards are then placed and installed. For insulation it is necessary to carry out the following steps:
Insulation of the veranda can be done both from the street and from inside. With insulation on both sides, it will be possible to achieve an incredible level of protection for the terrace during winter frosts, retaining much more heat.
To achieve an effective level of insulation of the veranda, the ceiling of the room must also be insulated. This procedure is quite labor-intensive. For high-quality work done, you should initially decide on the insulation and application or installation technology.
Thermal insulation of the ceiling in the attic is mainly carried out during the construction of the terrace, but if it was not there initially, then it can be built some time later. Sheets of polystyrene foam or other insulating material and vapor barrier are placed into the rafter frame.
It will be a little more difficult to insulate the terrace from the inside. The thermal insulation process can be done in one of several ways.
First way:
Second way:
Third way
To insulate the veranda yourself, you will need liquid polyurethane foam or polystyrene foam. But when placed on moving soils, the second one may crack, after which a waterproofing procedure will be required from the inside, because it will begin to draw moisture from the ground. Polyurethane foam is in a liquid state. It is sprayed onto the base, and when hardened, it forms a fairly hard coating.
The outer part of the terrace is insulated differently, depending on the base material. The wood surface is processed as follows:
Sheets of expanded polystyrene are glued to the constructed walls made of blocks or bricks and secured with dowels. The top of the slabs is also covered glue mixture and lay down construction mesh. Once dry, the surface is plastered and painted in the desired color.
Having learned how to insulate a veranda, many will be able to carry out the above steps on their own, without involving outside specialists. Having completed all the steps correctly, you don’t have to worry about a comfortable and cozy stay on the terrace even in winter, when there is a terrible frost outside the window.
Verandas (terraces) of private houses and summer cottages are usually not heated, so they are used as living quarters only in summer, late spring and early autumn. In winter, they serve as a kind of vestibule, in which only skis and sleds can survive. Is it possible to turn a cold veranda into extra room? Yes, you can. A properly insulated terrace will keep the house warm, the walls unheated room They will no longer freeze and become damp, and if you spend money on installing a heated floor or turn on the heater, you can fully use the “summer apartment” on frosty days. Choice thermal insulation material and the method of insulation depends both on the solvency of the property owners and on the stage at which the work is carried out: during the reconstruction/expansion of the house or during construction from scratch. How to insulate a veranda for winter accommodation, will be discussed below.
On cold days, heat can escape from the house in all directions: up, down and to the sides, that is, you should consider thermal insulation of the entire “envelope”: ceiling, walls, floor, windows and terrace doors. Many homeowners are mistaken in believing that heated air always moves upward. This is only one form of convection, in which warm currents primarily rise from the floor. In fact, they move in all directions. General rule: The greater the temperature difference, the greater the heat flow. Thus, the colder it is outside, the faster the heated air leaves the house.
An insulated terrace will “save” heat throughout the entire house
Is it possible to completely eliminate heat loss? Clearly not. But you can significantly reduce it by insulating the veranda according to all the rules. To do this, you need to know through which parts of the room the heated air “floats”. About 30–40 percent of heat loss typical house falls on the walls. The roof “takes” about 25 percent, windows and doors - approximately 20, and the floor - 10. A fairly large leakage of heated air occurs due to drafts, excessive ventilation and lack of tightness.
Thermal insulators are distinguished by structure: some resemble wool, others have tiny cavities - pockets filled with air, which has low thermal conductivity. The first include common mineral fibrous materials produced in rolls or in the form of dense “felt” slabs. The second are polymer-based insulation materials produced in the form of panels or foams.
Most wood-based products, such as MDF, plywood, and fiberboard, also have low thermal conductivity. That's why wooden doors, finishing MDF walls, covering the hatch to the attic with clapboard helps to retain heat.
Some sealants also “work” as heat insulators. They seal cracks and gaps. One of the cheapest sealants is papier-mâché; it can be easily made from paper and wallpaper glue.
Good insulating materials not only slow down the process of heat loss, but also have other important properties: fire resistance, indifference to chemicals, wear resistance, non-toxic, antimycotic (prevents the development of mold). However, one more significant factor is cost, therefore, when choosing thermal insulation materials, they are guided by the notorious price/quality ratio. We should not forget about the requirements set out in regulatory documents(GOST 16381-77, GOST 22950-95, GOST 31913-2011 and others).
Most often, the following is used to insulate walls, ceilings, floors, windows and terrace doors:
Foil penofol reflects about 95 percent of thermal energy
Relatively new material, successfully used in Europe and gradually conquering the domestic market - VIP vacuum insulating panels. They help out in cases where saving space is the main factor influencing the choice of material. Minimum thickness insulation allows you to maintain the height of the ceiling and eliminates the need to create a threshold between the terrace and the adjacent room.
Thermal conductivity of the panels is 0.007W/(m K). In terms of thickness/degree of thermal insulation ratio, this is the best of all available materials for insulation. VIP systems typically consist of highly insulated vacuum panels and sealing strips of appropriate thickness. Such panels are usually installed along the outer edge. Manufacturers of vacuum panels supply kits with attached instructions demonstrating the optimal layout of panels and sealing tapes, which helps reduce the thickness of the insulation system to a minimum. The new heat insulator has one drawback - the material is expensive.
Ultra-thin VIP vacuum insulation panels are 20 times more effective than traditional insulation materials
The disadvantages include the difficulty of performing reconstruction in bad weather.
To carry out work on insulating the veranda, no permits are required, therefore, having decided on thermal insulation materials, we begin the process. It is advisable to insulate the outside of the room in the warm season.
If the veranda and the house have a common roof and attic, then insulating the ceiling will not be difficult. Most convenient way– filling the frame cells with heat-insulating material.
Important! It is necessary to take care of vapor barrier.
What material should I use? Few a budget option: roofing felt is spread overlapping or the sheets are joined and glued, and a layer of expanded clay is poured on top or mineral wool slabs are laid. If possible, it is better to use foil-coated penofol, which retains heat well and does not allow moisture to pass through.
Ceiling insulation diagram from the attic side
The easiest way is to line the walls with sandwich panels, which use mineral wool, expanded polystyrene or polyurethane foam as insulation. The main advantage of such insulation is the combination of thermal insulation with external finishing, and you can choose almost any option for the outer layer: metal, PVC, and so on. When choosing decorative log or siding sandwich panels, the exterior of the house completely changes.
Thermal insulation with panels made of polystyrene foam, polyurethane foam or mineral wool is performed in two ways:
Insulation scheme brick wall outside
Ideally, it is advisable to install a ready-made entrance door with the provided thermal insulation (for a private house). If it is not possible to replace the door, then you should insulate the old one. To do this, foam rubber (you can get by with a blanket) is fixed with a stapler or glue, then leatherette is attached with furniture nails. A seal is laid around the perimeter of the door.
In ready entrance doors thermal insulation is provided for private houses
It's the same story with windows. It is optimal to replace old windows with double-glazed windows. If this option is not feasible for any reason, insulate the outside with ordinary plastic film. To do this, slats are stuffed onto the frame, and the film is attached to them with a stapler.
If the roof structure does not allow external thermal insulation of the ceiling, you have to “take away” the height from the room and insulate it from the inside. A frame is mounted on the ceiling, taking into account that the cross-section of the beam must correspond to the thickness of the insulation boards. Using umbrella dowels, the heat insulator panels are fixed and a film is laid to protect against steam. The resulting “sandwich” is covered with plasterboard. If you don’t want to lower the ceiling height, then use vacuum insulating panels, which take up virtually no space.
Important! Be sure to insulate the hatch to the attic: seal the cracks, lay a seal around the perimeter, and sheathe it.
Veranda ceiling insulation technology
They begin work by removing the old coating and cleaning the walls from dust. When using mineral wool or expanded polystyrene, first prime the surface and lay a layer of waterproofing. Then the frame is mounted (it is more convenient to use metal profiles) and the thermal insulation panels are attached. The insulation is covered with a vapor barrier film. The final stage is installation of drywall, puttying and application finishing coating.
Changing the location of the dew point when insulating walls from the inside
Experts advise using ready-made electric floor heating modules to insulate walls from the inside and turning on the system on cold days/nights. This method of insulation is very expensive, but it guarantees a dry and warm wall.
Double glazing is considered effective way reducing heat loss, however, is relatively expensive. To save money, you can “preserve” the window for the winter in another way: attach a regular film to the frame using double-sided adhesive tape. Yes, it’s not entirely aesthetically pleasing, but it’s warm. It is advisable to seal all cracks with self-adhesive foam strips. You can do it the old fashioned way: with paste and paper, after caulking it with cotton wool or foam rubber. Thick curtains with thermal lining are an additional way to protect the veranda from heat loss through the windows.
Even when installed modern doors with thermal insulation from below it usually “pulls”. In Europe, it is customary to make a special roller and place it under the door. The British jokingly call him a dachshund. Making such a “dachshund” is simple: stuff the stocking with old socks or other rags and tie it (the length of the “sausage” should be equal to the width of the door). The top decorative “pillowcase” can be knitted or sewn.
If there is a basement under the veranda, then insulating the floor is easier - there is no need to dismantle the existing flooring.
Stages of work:
Wooden floor insulation scheme
If there is no basement under the veranda, floor insulation work is moved indoors. If the owners of the house do not plan to start major renovation terraces, then tearing down the old flooring just to lay thermal insulation is not worth it, since the result will be too labor-intensive and costly a method of insulation. Typically, logs are installed on top of the existing covering, expanded clay is poured in, or insulating panels are laid and a new floor is laid. True, in this case the floor level rises higher and a threshold appears between the veranda and the next room. How to avoid this? Vacuum insulating panels “soldered” into MDF can be used. They will raise the floor by only 30 mm. The second way is to dismantle part of the covering and insulate it with ecowool, but this will require special equipment, since the composition is supplied under pressure. Another option is to install a “warm floor” system. You can do with little: carefully seal the gaps between the floorboards, fit the baseboards well and lay a thick carpet on the floor.
Insulating the floor over the existing coating
Note! With any method of insulation, one must not forget about reliable waterproofing.
Insulation of the veranda, despite the abundance of thermal insulation materials and the apparent simplicity of their installation, is sufficient labor-intensive process. Therefore, it is better to entrust the work to specialists from a construction company. They will produce necessary calculations and insulate the veranda according to all the rules.
The issue of thermal insulation of the veranda becomes relevant when there is a desire to use this room all year round. Verandas are usually unheated, as a result of which the temperature in them can drop below zero in winter.
If you want to provide comfortable temperature air inside the veranda even in the coldest season, you need to take care high-quality insulation extensions.
With comprehensive thermal insulation using proven materials, and installation of basic heating device: a small solid fuel stove or a good electric radiator can ensure a constant temperature in the veranda at +18+19 degrees.
It’s worth mentioning right away that since the construction of a veranda is usually budget project, as a result of which it is built from inexpensive materials- wood, cinder blocks, or gas silicate blocks, the veranda will have to be insulated comprehensively.
You can, of course, only insulate the walls and even insulate the ceiling, but you will not get the desired effect from such thermal insulation.
To turn a veranda into a full-fledged year-round living space, it is necessary to insulate both the surface of the walls from the outside and the ceiling, walls and floor from the inside of the building.
If savings are at the forefront of the insulation project, then ordinary polystyrene foam can be used as a thermal insulation material. This material has good thermal conductivity and is inexpensive.
Also, polystyrene foam is easy to work with, even one person can handle it without any problems, so if you plan to do everything yourself, polystyrene foam - a good option from inexpensive insulation materials.
The thermal conductivity of polystyrene foam is approximately 0.04 W/mK per , which is, of course, less than that of mineral wool or extruded polystyrene foam, but also quite good, considering the cost of this material.
To insulate walls, ceilings and floors, you can take foam plastic 5 centimeters thick - in most cases it will be quite enough.
Expanded polystyrene benefits not only in its thermal insulation properties. An important fact is that this material has minimal vapor permeability and hydrophobicity, as a result of which condensation will not form on its surface, which is the main enemy of most insulation.
The advantages of polystyrene foam also include ease of installation - this insulation is manufactured in the form of slabs measuring 100*160 cm, for installation of which in most cases only an adhesive solution is sufficient.
