The main task of the homeowner is to keep the heat in the house. Heat leakage entails an increase in the cost of coolants. Special materials will help to keep the heat inside the house. Let’s talk about the insulation of the facade of the house, how to properly carry out the finishing and consider the main types of insulation.
Why is insulation and decoration of the facade of a house needed?
Insulation of the facade of a private house is necessary in order to retain heat in the premises and reduce the cost of the heating and air conditioning system. There are many ways to insulate the walls of a house. External insulation is more effective than internal. Insulation protects the building from wind, precipitation, mechanical damage and increases the service life of the structure.
External insulation of the walls of a house made of aerated concrete blocks has its advantages:
- Attractive appearance;
- No space is lost inside the building;
- Increased service life;
- Moisture will not accumulate in the wall and destroy it;
- High-quality soundproofing.

The effectiveness of wall insulation with foam has long been proven, so it often acts as a heater. This is an affordable, waterproof material. The plates are lightweight and easy to mount on the wall. You can use glue.
Types of insulation for the facade of a residential building
After the construction of a private house is completed, the question arises of what type of insulation to use. Currently, insulation with polystyrene foam, mineral wool, and polyurethane foam are popular. All of them have good characteristics and are safe for human health.
Insulation of aerated concrete with mineral wool under siding is permissible. The special structure of mineral wool blocks ensures air circulation. Aerated concrete houses have high vapor permeability, so the wrong choice of insulation can harm the structure. It is important to strictly adhere to the installation technology.
Before you start insulating the exterior walls with foam plastic, you should prepare them: clean, level, prime. The slabs can be laid using glue or “umbrella” dowels.
Insulating the facade of a house with expanded polystyrene is one of the most effective methods. The material does not allow air to pass through. It is not recommended to use it indoors.
How to properly finish the facade
The facade is the calling card of the house. The technology of finishing the facade is different. The modern market of finishing materials offers a wide choice: siding, decorative plaster, facing brick, thermal panels, porcelain stoneware, etc.

Finishing the facade of the house after insulation with foam plastic involves mandatory plastering after completion of the work. Protective plaster guarantees high performance characteristics of the structure. Foam plastic sheets are attached to the walls using mineral glue.
When insulating and plastering the facade of a house made of aerated concrete, it is better to use breathable mixtures, for example, silicate or silicone. Plaster allows you to get a vapor-permeable layer. Plastering the facade is the last thing to do, when all the materials are well dried. Otherwise, with the onset of cold weather, the facade plaster will deform. If frost has prevented the completion of construction, it is better not to plaster.
Compliance with facade work technologies is the key to a long service life of the house decoration. If you are not sure that the independent work will be carried out at a decent level, it is better to turn to professionals.
