How to choose a heater for the walls of a frame house

The insulation for the walls of the frame house is selected depending on the structure of the walls, the material of manufacture of the frame and its thickness. These three indicators are needed for high-quality thermal insulation.

Today we’ll talk about how to insulate walls in a frame house and what is better to use for this. Also in the video in this article you can see the different finishes and pick the right one from the photo.

Types of frame houses

Insulation will be selected and depending on the material of the frame house. Therefore, before making a decision and such a construction, it is necessary to choose the right manufacturing material.

There are several options for such buildings:

Rules for warming frame houses

Insulation for frame walls is determined by the structure itself. There are two options and how to insulate the walls of the frame house is determined precisely by them.

Let's look at these two options:

Thermal insulation of the walls of the frame house from the inside Application of thermal insulation indoors	For this, only lightweight materials are suitable. The method itself is not effective enough, but if you have a small foundation, then it will do. Attention: The main disadvantage can be considered this decrease in the usable area indoors.
Thermal insulation for the walls of the frame house outside How to insulate frame walls outside	This method is most effective. It is possible to use almost any insulation (if the width of the foundation allows). You do not take the usable area, so you do not have to save on the thickness of the material.

Attention: What to insulate the walls of a frame house should not forget about the parameters of insulation. Their thickness affects not only the thermal insulation, but also requires additional space. In the photo below you can see the necessary parameters.

We choose the insulation material

In principle, all work can be done with one's own hands. Instructions for performing work on insulation are on all types of material on our website.

Now we will choose the right insulation. First of all, we do the thermotechnical calculation of the frame wall with the materials used. The structure of the insulation and its thermal conductivity are important here. In the photo you can see these indicators.

How to insulate the walls of a frame house from the inside according to the structure of the insulation

Now let's look at what insulation is best for the walls of a frame house, depending on the type of material.

Feature of stone wool slab

The most common and demanded among developers is the products of such companies as TekhnoNIKOL and Rokwool. When choosing insulation material for home decoration, stone wool slabs are most often used.

Due to the great popularity of their application, several points can be noted that explain this:

• For their use and application absolutely no additional devices are required.During installation, you will need a regular knife and a hacksaw with small teeth;
• At the initial stage of warming the frame of the house, a large amount of insulation material will be required and in this case, you can certainly use the services of paid delivery. Usually rarely anyone can accurately calculate the right amount of material, but you can always buy the right amount of material and deliver it yourself or order delivery. But if the structure is small, then you will certainly bring in the entire amount of materials that you need;
• When working with this type of material, you must always know that stone wool slabs must tightly fill the gaps between the racks of frame houses, while remembering that it is completely forbidden to compress and ram them!
• Further, the insulation materials laid in the place between the racks must be fenced off from moisture that comes both from the outside and from the outside, and this can be done with the help of a waterproofing film from the outside and a vapor barrier inside. It is important to take into account the prices of these films when calculating the total cost of insulation work with such plates.

Ecowool

A material such as cellulose fibers, in other words “ecowool,” also began to be in great demand for insulation. This product is completely natural and does not require additional use of films, which will help you make the house as environmentally friendly as possible.

We also consider several points that characterize this material: Ecowool attaches quite simply and this makes it stand out in comparison with other materials.

Ecowool insulation

• In order to insulate the walls in a dry way, you will need to open what the packaging contains and beat. Further, the already whipped material is ready for use, which means you can ram it into the walls to obtain the desired density. You can also use a special machine and make a blowing of the material, which will create the desired density;
• This material has a particular shrinkage, which means that a dry installation method will not always give you exactly the results that you want. After fiber shrinkage, heat loss occurs, which is a big disadvantage. But it should be noted that upon purchase of ecowool a guarantee is always given for 15-20 years that this material will not undergo shrinkage;
• The wet method implies that it is necessary to use certain equipment, due to which the fiber is sprayed onto the walls, thereby gluing it to the frame. In this case, fiber shrinkage does not occur. This method of insulation should be applied outside the walls before they are sheathed, but this is not always possible, and this is a minus.

Styrofoam

When looking for information on the forums, you can see that there are many discussions about the pros and cons of polystyrene, as an insulating material (seeHow to properly insulate a wall with a foam tile) Some believe that this material is not environmentally friendly, when ignited, it releases hazardous substances into the air, and the possibility of the appearance of rodents is not ruled out.

We warm the frame house with polystyrene

But first things first:

• There are also cases where people insulated their house with polystyrene foam (seeHow is wall polystyrene insulation) and having lived in it for about 5 years were more than happy with the quality of the material they chose. Having chosen this material, they did not find any difficulties with well-being, and also noted the absence of rodents.
• However, there are episodes when the developer changed the foam completely a year later due to the destruction of it by rodents. This material should not be written off, because, like all heaters, it has its pros and cons.
• The value of this material is that it does not absorb dampness at all, which means that additional methods of protection will not be needed.It is important when choosing a foam that is not pressed. This method of insulation is the cheapest in comparison with the rest.
• But he needs the greatest accuracy and skill. The specifics of this insulation were mentioned in the article “The step of the racks in the frame house”.

Attention: Rodents are started in the foam, therefore it is better not to use it for a private house.

Sprayable heaters

This type of home insulation is not yet widespread enough, and of the most famous materials - it is polyurethane foam. Polyurethane foam - these are two special liquid elements, when mixed in all sorts of proportions and when exposed to air by pressure, they foam.

When using this material, they fill all the spaces between the racks, and when excess appears, they are cut off. Working with such a heater is a bit similar to working with polyurethane foam (seeLiquid thermal insulation for walls: features of use).

Internal insulation with a sprayed heater

This material has its advantages.

Consider each of them:

• Polyurethane foam is able to interact with absolutely all surfaces that are used in the construction of houses. This material has a special quality that allows it to take various forms, thereby simplifying the application. It is also important that it is not necessary to process the surface before using the material;
• The material for insulation is created directly on the spot. Transportation costs are also reduced, and material consumption is minimal;
• Due to its structure, polyurethane foam is light and airy, which means they can easily insulate roofs;
• Creating coatings with this material, not only wall insulation is created, but their strength also increases;
• This material is able to tolerate high temperatures, which makes it completely universal;
• The use of polyurethane foam provides a unified insulation design without any joints and seams.

It should also be noted all the disadvantages of this insulation material.

There are only two minuses:

• It wears out quickly if it is constantly exposed to ultraviolet radiation. For the normal functioning of this insulation system, it is necessary to create high-quality protection. Such protection can be plaster or paint, which can protect the material from the sun, as well as make the appearance of the insulation more attractive;
• It has already been noted in the text that this material for insulation is practically non-combustible, but it begins to smolder when exposed to high temperatures. It is absolutely not difficult to stop this process, because for this you only need to cool the material. But in places of strong heating of polyurethane foam, it is better to replace the insulation material with another.

Differences in warming frame house materials

Basically, insulation is done when installing the frame. Let's look at how to make a frame for wall insulation in different ways.

Warming of wooden frame houses

The main feature of such houses is that the corners between the logs form cracks that allow wind and frost into the house. It is important that when winter arrives, it is correct and high-quality to independently check the walls from the inside to identify blowing.

Timber frame insulation structure

Attention: When making a frame for insulation, it is necessary to take into account the air gap. After all, ventilation is required here. Otherwise, the wall material will quickly become worthless.

• First you need to find all the places that the wind blows. It is also necessary to find areas of the house that get wet. All found areas must be examined for cracks and cracks.
• Further, all found cracks and cracks need to be thoroughly caulked or filled with foam. If necessary, you can clean the inside of the house from the finish.
• It is much more difficult to insulate the ceiling, because it is not always possible to find all the places in which heat loss occurs.To eliminate such problems, a variety of sawdust, mineral or ecowool, is usually used. The use of loose heaters is simple and for this you only need to take them on your own.

Attention: It is important to note that the insulation layer must be no more than 15 cm.! Most specialists in this field do not recommend covering the insulated surfaces with roofing material and other similar products.

It is better to put such insulation materials from below. When warming the walls, you should make overlaps in the corners, along the edges, creating the best warming. By warming the walls, laps are cranked on each side.

Features of insulation of metal frames

The instruction for wall insulation of a frame house made of metal is quite simple. Indeed, in this option, you yourself choose a heater that is placed inside the wall and it is important to consider everything here at the initial stage of installation.

Metal frame structure

• First of all, we look at what the heating system will be, about which we calculate the thickness of the insulation;
• We also pay attention to the foundation of the structure. After all, he should be more material throughout the decoration;
• We take into account the ventilation gap, because condensate should not accumulate and the channel itself can not be less than two cm.

Feature warming frame-panel houses

There are a number of types of frame panel houses:

What do we pay attention to when warming

Consider the features of insulation:

• For proper insulation, it is necessary that the wall thickness of the structure is accurately calculated, in compliance with all orders and parameters. When warming such a house, it is necessary to lay insulation materials directly into the wall;
• To start warming a similar building as a frame-panel house, you need to carefully process each joint with foam or mastic. Installing airtight membranes will help improve the insulation of walls, as well as make the house durable and reliable in cold periods of time;
• Before starting the insulation of the frame-panel house, it is necessary to install horizontal profiles that are fixed with dowels. Further, the walls on each side are sheathed with lining. However, it should be noted that the lining must be dry inside, and wet - directly from the outside. Insulation should be laid inside each side;
• In such houses, insulation is necessary for both the walls and the floor. Often, penoizol is used to warm the floors;
• After all the work on the insulation of such a house, each wall should be sheathed with siding or a panel for the facade. The easiest method of warming is considered to be the filling of all the gaps between the panels with insulation material. On top of all this, it is necessary to apply a mastic, which will protect the insulation from moisture and ultraviolet radiation.

The technology of warming metal-frame walls is somewhat different, here it is quite possible to mount using simple glue. And the rest of the instructions for choosing the material and installation rules are the same as in other buildings. If you think it over and do it using only high-quality materials, then the energy-saving facilities will be at their best.
