Brick house insulation
As you know, a brick house by itself has the ability to keep warm, you can live quite comfortably in such a house and without additional insulation. But to minimize heating costs in this case is unlikely to succeed. That is why the issue of warming brick houses remains relevant.
How to conduct insulation - outside or inside? Which thermal insulation materials should I prefer? How to minimize heat loss? Let's consider these questions in more detail.
Insulation from the inside and outside: what is important to consider
As a rule, experts recommend that a brick house be insulated outside. This allows us to exclude such a moment as the appearance of condensation on the walls: if the insulation is only from the inside, the wall itself will not warm up, as a result, damp will begin to appear and accumulate under the thermal insulation layer. Over time, the smell of dampness will begin to appear in the house, mold and fungus on the walls.
That is, if you have a choice - to make insulation from the outside or from the inside, then the choice in favor of external insulation is obvious. If the budget allows and there is a desire to carry out additional thermal insulation inside the house, then you should not refuse external insulation, otherwise the result will not please its effectiveness for long.
As for the insulation from the inside, it is first necessary to take into account that the footage of the room is reduced. Before installing the insulation, it is necessary to build and fasten the frame (crate) to the brick wall. It can be wooden or metal. Subsequently, the insulation is laid between the frame and the brick wall. As a final step, there may be a wall sheathing, for example, plasterboard.
Internal insulation: practical and popular organization schemes
For the insulation of brick walls, a variety of types of thermal insulation materials can be used. The main thing that you should pay attention to is that the thermal insulation is environmentally friendly and harmless, because people will always be in the house.
One of the most common due to its cost-effectiveness, environmental friendliness and high efficiency of insulation schemes for brick walls on the inside of the house is:
Layer 1 - brick foundation (the wall itself);
layer 2 - thermal insulation wool;
layer 3 - vapor barrier;
layer 4 - thermal insulation plate MDVP;
layer 5 - drywall.
The first stage of work is the preparation of a brick wall, it is leveled, primed if necessary. It is not necessary to chase absolute evenness, because all errors will be hidden by a heater. Further, it is advisable to lay a waterproofing on the entire surface of the walls, it will eliminate the penetration of moisture into the insulating layer from the outside.
The next stage is the installation of the frame, it is made of wooden or metal battens. The distance between the rails is calculated based on the size of the selected type of insulation, the width of which should be slightly wider than the distance between adjacent rails in the frame.
The main requirement is that the thermal insulation wool fill the space between the wall and the frame as tightly as possible. If necessary, you can stack it in 2 or even 3 layers.
To exclude the accumulation of moisture and dampness, as a result - the formation of fungus and mold in the insulation, the next layer is laid - vapor barrier.
To ensure the highest degree of thermal protection, another layer is installed - thermal insulation boards. Boards made of soft fiberboard proved to be excellent. With their help, such a problem as effective sound insulation of the house is also effectively solved.
Plasterboard sheets are used as the finishing covering that hides the layers of insulation and provides the walls with a perfect appearance. They can be wallpapered, painted, etc.
Another scheme of internal insulation, which has proven itself well, involves:
Layer 1 - brick wall;
layer 2 - installation of bars (fixing them to the wall) or fixing insulation without bars, directly on the brick base with dowels;
layer 3 - thermal insulation plate;
layer 4 - drywall.
Wooden blocks are attached to a brick wall at a certain distance (slightly less than the width of the selected type of heat-insulating boards). Further, heat-insulating boards are fastened onto the bars (often a soft Steico fiberboard is chosen). The process of finishing the insulation with drywall completes the process.
In this case, it is recommended to use MDVP boards, since it is an absolutely natural material with remarkable characteristics and properties. It will provide proper thermal insulation and good sound insulation of the room, without harming the health of residents, even if they have a sensitive, prone to irritation and allergies body.
When external insulation of the walls of a brick house is necessary
As already noted, it is necessary and most rational to insulate brick walls from the outside. To do this, it is effective to use special windproof plates that do not allow cold and piercing winds characteristic of the cold seasons to penetrate walls and blow heat out of the house.
We offer the following option for organizing external wall insulation:
Layer 1 - brick wall;
layer 2 - windproof plate;
layer 3 - crate;
layer 4 - the selected type of facade decoration.
A lath is attached to the brick wall (as a rule, vertically directed slats at a distance slightly less than the width of the selected type of wind protection). Further, the space between the slats is filled with insulating material, as a finishing coating that hides the thermal insulation, you can install any kind of decorative facade decoration that you like.
If internal thermal insulation was not carried out, then it is important to install not only windproof, but also thermal insulation material from the outside. In this case, the wall insulation scheme will look like this:
Layer 1 - brick foundation (wall);
layer 2 - thermal insulation material;
layer 3 - windproof plates;
layer 4 - crate;
layer 5 - decorative facade decoration.
With this approach to organizing heat in the house, it is worth using soft wood fiber boards. Having a porous, but sufficiently strong structure, they are highly effective and reliable, less prone to the spread of fire, environmentally friendly.
As you can see, warming brick walls is not a very difficult task, although it has its own nuances and features that directly depend on the type of heat-insulating material chosen and the place of its installation (outside or inside).
