Thermal insulation of a frame house. Sediment insulation materials.

Thermal insulation of a frame house should have a number of properties that ensure a comfortable stay. The main qualities that should have a thermal insulation material:

— ecological purity, The absence of harmful vapors.
— The maximum long life.
— Humidity resistance - opposition to the absorption of moisture, which can affect the destruction of the wooden frame.
— The high coefficient of heat preservation. This - the main indicator that provides heat to the frame house.
— The water vapor permeability. If the material is not "breathing", its surface can accumulate moisture, promote the formation of fungus and mold.
- Fire safety. Ideally, it is best to install a non-combustible material. In an extreme case - resistant to fire.

Types of insulation materials

All insulation materials can be divided into types according to the method of installation:

- Loose-fill insulation materials.
- Evaporation heaters.
- Boards, as well as roll materials.

Sediment insulation materials. expanded clay aggregate

Expanded clay - natural insulation material produced from refractory clay by thermal treatment. This material has a low weight, which greatly reduces the load on the foundation, can not be adversely affected, environmentally friendly, it "breathes", not retains moisture, it does not develop bacteria do not live rodents, it is safe to Allergy. The main disadvantage of expanded clay - low insulation performance. For good performance is required to make the thickness of 20-30 cm layer of filling.

Foam glass - beads

This material has a higher insulation performance than expanded clay. It is made of thermally glass breakage in a mixture with sand. This is - an excellent material for thermal insulation: eco-friendly, do not emit pollutants. It protects the building against rodents. Used for insulation of floors, ceilings, attics, as the backfill material in the cavity walls. The main drawback of the material - the higher price compared with the expanded clay.

Ecowool (the filling variant)

Ecowool made from cellulose with the addition of preservatives and fire retardants, ensuring safety and fire safety. Ecowool is filled in by hand or with the help of special equipment prepared space is blown under pressure. The main advantages of Cellulose Fiber:

- High thermal insulation properties.
- Easy.
- Environmentally friendly.
- vapor permeability.
- Resistance to harmful biological destructive influences.
- Slabogoryuchest - thanks to special additives.
- Part of the material repels the boric acid rodents.

Sawdust

This material was used as insulation since time immemorial. In a modern frame construction it is rarely used in connection with a number of disadvantages:

- high flammability.
- You like to settle rodents.
- Sawdust shrink.
- When moisture-laden dust begin to rot.

In most cases dust is used in a mixture with the clay, and concrete with addition of antiseptic materials.

In the next article we will talk about the warming of the frame house with the help of the deposited materials.
