Wall of a frame house: sequence of layers; materials; installation requirements Part 2

A frame house is a lightweight and pre-fabricated structure that has high strength and thermal insulation characteristics. This is achieved due to the multilayer walls, where each material performs its own, strictly defined function. IN first part we examined: the principle of the skeleton wall pie; exterior cladding materials; installation rules. In this part, we will touch on heaters.

Insulation for walls of a frame house

About frame houses they say that they consist of 80% insulation. This is true, because the entire free space of the wall is filled with thermal insulation. For this reason, you need to responsibly choose a heat-insulating material, since this is one of the main guarantees for a comfortable stay.

Consider the main types of heaters for a frame house, their pros and cons. This section will not touch upon "folk" materials, such as straw, sawdust, sawdust concrete, expanded clay and others. These materials are inferior in thermal insulation qualities to specialized heaters and require thickening of the walls.

Mineral wool and its varieties: stone, basalt wool

Mineral wool and its varieties are one of the most popular types of insulation in our country. It is made by obtaining fibers (threads) by melting: glass (glass wool); rocks of volcanic origin (basalt wool); slag (slag wool). Mineral wool is produced in the form of rolls and plates.

The advantages of this insulation are considered to be: low thermal conductivity - 0.038-0.047 W / m * K; soundproofing qualities; vapor permeability; environmental friendliness; incombustibility - fire hazard class NG. Of course, the incombustibility of mineral wool is an advantage, as they say, sucked from the finger: the frame consists entirely of wood, and this quality is unlikely to save in a real fire.

The disadvantages of cotton wool can be considered: moisture absorption and the loss of all advantages when water gets into the material; shrinkage. Manufacturers write: mineral wool shrinkage is negligible. But it should be understood that it is in the walls of a frame house that shrinkage is a significant disadvantage. The frame house is not concrete and has the properties of “moving”. This happens for various reasons, including slamming doors. Each vibration shrinks the fibrous materials, which will definitely require a complete replacement of the insulation after 15-20 years of operation. And also rodents and insects like to settle in mineral wool, but this can be attributed to the general lack of frame housing construction.

Expanded polystyrene(PPP)

PPP is polystyrene. Fully synthetic insulation. Among the pluses it can be noted: cheapness; ease of styling; low specific gravity; high thermal insulation qualities; mold resistance; low shrinkage; durability.

Foam has a lot of disadvantages, the following can be distinguished: moisture absorption - up to 2% by volume (for comparison, mineral wool has moisture absorption of 0.09-1.9% by volume); fire hazard class G3; toxicity; PPS adore rodents. Here it is worth paying attention to the toxicity and fire hazard. PPP releases toxic substances over time and when heated, and even a wall heated by the sun can be considered heating. But the fire hazard of foam is a serious matter: in the event of a fire, you may not have time to run out of the house - the release of foam during combustion has strong poisonous properties.

Extruded polystyrene foam (EPS)

EPPS is a derivative of PPS obtained at high: temperature and pressure. But due to the high-tech production method, EPSP in all its qualities significantly exceeds the foam plastic. The obvious advantages of extruded polystyrene are: high strength with relatively low weight; ease of installation; frost resistance; resistance to deformation; high thermal insulation qualities; low moisture absorption (no more than 0.4% by volume), resistance to mold and decay; durability.

The disadvantages of EPSP are practically the same as those of polystyrene, but with the addition of poor sound insulation and high cost. Insulating a house with extruded polystyrene is not a cheap pleasure.
