Insulation system of low-rise buildings on a wooden frame

Residential development of agricultural territories involves the use of low-cost construction solutions to provide housing for emerging new farms or implemented during the development of gardening plots. In this case, it is advisable to construct frame buildings with effective insulation systems.

The article presents the results of studies of the properties and application features for warming wooden structures of rolled foam polyethylene with or without a metallized coating. The tensile strength tests in the longitudinal direction were carried out in accordance with the standard. It was found that the tensile strength in the longitudinal direction for products with a metallized coating is 80–92 kPa, without a metallized coating – 80-87 kPa, and for a weld - 29-32 kPa.

As a result of the studies, insulation systems were developed (which have found wide practical application) and a full-scale thermophysical assessment of the thermal characteristics of these systems and the condition of the wooden frame in the building was carried out.

The results of experimental determinations of the resistance of the outer wall of a wooden frame with a warming sheet of foamed polyethylene amounted to: thermal resistance 2.96 m² °C / W, heat transfer resistance 3.12 m² °C / W. The specific humidity of the pine timber was 7.7–7.8% - at the level of equilibrium humidity values. No putrefactive manifestations of the wooden frame were found, which confirms the advisability of using these insulation systems for the construction of rural residential buildings.
