Property Changes of Thermal Insulation Material due to the Effects of Environmental Conditions

Ventilated facades are widely used in modern energy efficient building, and it leads to topical issue whether it is important or not to stick to assembling terms of such kinds of facades. The first thing to do during the ventilated facades installation is to built in the mineral-cotton insulant which will be later protected by vapor proof material. Thus, the shield obtained on the exterior side of the building in the aggregate with ventilated clearance and facing material form a system with high insulation and resistant to environmental attacks. This article observed a situation in which the terms of ventilated facades installation were broken after the primary stage (not more than 90 days). The works were stopped for 1.5 year after fixing the heat-insulation material to the inclosing walls of the building. As a result, insulants were exposed to significant temperature and humidity changes, wind forces and UV rays. The main objective of this research is to determine the suitability of insulating material for further use taking into account changes in its basic parameters, which are determined by laboratory tests.
