Wall insulation wooden house inside and out - choose material

Why do we have to insulate wooden buildings?

Everyone would like to have a comfortable house, and if he is also a wooden, then it is - a dream.That it was a dry, durable, warm and economical, you need to pay attention to all of this is still in the design and construction of the house.The key to energy efficiency and durability is a quality insulation, under which there will be to gather moisture and plants microorganisms, damaging the tree.

During operation of structures made of wood need to be diligent care, because the logs slowly crack due to evaporation of moisture, which is present in the wood, and the walls are subjected to shrinkage.This causes additional losses of the hot air, increasing heating costs.

There are several ways of warming:

• insulation wooden walls from the outside - is laying insulation material between the wall and the inside walls of the house.
• insulation wooden walls inside - is the structural unit of plasterboard, which fits into the middle of the insulating material.

compare materials to create the warm habitation

So to make wall insulation of a wooden house from the outside, you can use the following materials:

1. Extruded polystyrene

Advantages:

• has the lowest thermal conductivity;
• low water absorption due to closed cellular structure;
• resistance to chemical decomposition and different biological effects;
• maintains its quality under any mechanical stress;
• durable;
• not infest rats and ants.

Disadvantages:

• not environmentally friendly;
• relatively expensive compared to the foam.

2. Glass wool

Advantages:

• durable and resilient material;
• good conductor of hot air;
• low price;
• easy installation.

Disadvantages:

• low density;
• crumbles from mechanical impact;
• work with it is not safe, it is necessary to use protective equipment.

3. Mineral wool

Advantages:

• can be used at high temperatures;
• not subjected to shrinkage with time;
• well delay the heated air in winter and blocking heat the house in the summer;
• good sound insulation - prevents the penetration of noise through the walls;
• resistance to flame;
• vapor permeability, steam passes through its fiber and does not absorb it.

Disadvantages:

• price is higher than that of glass;
• not safe for health.

4. Foam

Advantages:

• it keeps heated air;
• not infest rats and ants;
• low cost;
• insulation foam wooden walls increases the service life;
• easy installation;
• lends itself well to cutting;
• not flammable.

Disadvantages:

• toxicity smoldering;
• in poor waterproofing of moisture may occur fungal mold;
• relatively short shelf life.

5. Basalt wool

Advantages:

• low thermal conductivity;
• long service life;
• not subjected to the formation of mold and mildew;
• resistance to UV;
• not destroyed by vibration;
• high quality sound insulation;
• non-flammable, fire-proof and explosion-proof;
• not destroyed by changes in temperature;
• environmentally friendly.

Disadvantages:

• high price;
• can have in their construction joints and cracks, which eventually can skip the warm air out.

6. Thermal insulation plaster

Advantages:

• provides maximum thermal insulation;
• good waterproofing;
• high vapor permeability;
• excellent sound insulation;
• decorative trim.

Disadvantages:

• huge hygroscopic material;
• high cost.

Features Technology insulation wooden house

Experts recommend doing external thermal insulation of buildings, for insulation of walls inside a wooden house has its drawbacks:

• area indoors is greatly reduced;
• between the insulation and the wall condensation;
• walls of the house are in front of a heater, so the wood is in the sub-zero temperatures, which is why cracks over time.

Technology insulation wooden walls should be as follows.The layers are arranged according to the principle inside out.The first layer - a vapor barrier, it does not let the moist air.Second layer - insulation, insulating material itself directly.The third layer - waterproofing, she misses pairs and retains moisture.

As for the material, which is better to use for home, it depends only on you, having familiarized with the properties possible, choose the most suitable.

On the Internet there are many videos "insulation of walls of wooden houses," which are available to make installation himself.The main thing - to follow the recommendations.
