Why do we have to insulate wooden houses?
Everyone would like to have a comfortable home, and if it is also wooden, then this is a dream. To make it dry, durable, warm and economical, it is necessary to pay attention to all this during the design and construction of the house. The key to energy efficiency and durability is quality insulation, under which moisture and microorganisms that damage the tree will not be collected.
During the operation of the structure of wood in need of conscientious care, because the logs are slowly cracking due to the evaporation of moisture, which is present in the wood, and the walls are shrunk. This is the cause of additional losses of hot air, increasing heating costs.
There are several ways to insulate:
- insulation of wooden walls from the outside - is to lay insulation materials between the facing and internal walls of the house.
- warming of wooden walls from the inside - is the construction of structures from gypsum board, in the middle of which the insulating material is laid.
Compare the materials for creating a warm housing
So, to make the insulation of the walls of a wooden house from the outside, you can use the following materials:
1. Extruded polystyrene foam
Advantages:
- has the lowest thermal conductivity;
- low water absorption due to closed cellular structure;
- resistance to chemical decomposition and various biological effects;
- retains its qualities under any mechanical stress;
- is durable;
- is not planted with rats and ants.
Disadvantages:
- is not environmentally friendly;
- is relatively expensive compared to polystyrene foam.
2.
glass wool Advantages:
- is a durable and resilient material;
- conducts hot air well;
- low price;
- simple installation.
Disadvantages:
- low density;
- crumbles from mechanical impact;
- work with it is not safe, it is necessary to use means of protection.
3. Mineral wool
Advantages:
- can be used at high temperatures;
- does not shrink with time;The
- well retains heated air in winter and blocks the heating of the house in the summer;
- good sound insulation - prevents the penetration of noise through walls;
- flame resistance;
- vapor permeability, passes steam through its fibers and does not absorb it.
Disadvantages:
- price is higher than that of glass wool;
- is not safe for health.
4. Foam plastic
Advantages:
- keeps the heated atmosphere well;
- is not planted with rats and ants;
- low cost;
- thermal insulation of wooden walls with polystyrene increases the service life;
- simple installation;
- is well cut;
- is not flammable.
Disadvantages:
- toxicity in decay;
- with poor waterproofing from moisture may appear fungal mold;
- relatively short shelf life.
5. Basalt wadding
Advantages:
- low thermal conductivity;
- long service life;
- does not undergo fungal and mold formation;
- resistance to ultraviolet;
- does not collapse during vibration;
- high sound insulation qualities;
- is non-flammable, fire-safe and explosion-proof;
- is not destroyed by temperature changes;
- is environmentally friendly.
Disadvantages:
- high price;
- can have joints and slots in its design, which in time can pass warm air to the street.
6. Thermal insulation plaster
Advantages:
- provides maximum thermal insulation;
- good waterproofing;
- high vapor permeability;
- excellent sound insulation;
- decorative finishing.
Disadvantages:
- huge hygroscopicity of the material;
- high cost.
Features of the technology of insulation of wooden houses
Specialists recommend making external insulation of buildings, because the insulation of the walls from inside the wooden house has its drawbacks:
- the area inside the premises is significantly reduced;
- a condensate forms between the heater and the wall;
- the walls of the house are in front of the heater, so the wood is in sub-zero temperature, which causes it to crack over time.
The technology of thermal insulation of wooden walls should be as follows. Layers are arranged on the principle from the inside out. The first layer is a vapor barrier, it does not let the moist air pass. The second layer - thermal insulation, directly the insulating material. The third layer is a waterproofing, it passes steam and retains moisture.
And as for the material, which is better to use for arranging a house, then it depends only on you, having become acquainted with the properties of possible, choose the most suitable.
On the Internet, there are many videos of "warming the walls of a wooden house", which you can see to make the installation yourself. The main thing is to follow the recommendations.
