OPERATION OF INSULATORS WITH NON-VENTILATED AIR LAYERS AND ENERGY-REFLECTIVE SCREENS

Abstract

The quality of insulation of construction structures - houses and buildings of various purposes - depends on many components, but the main ones were and remain the quality and durability of the materials used. Typical tests are carried out according to indicators of the resistance of the structure with facade thermal insulation to climatic factors and according to the indicator of the reduced heat transfer resistance of the prefabricated system with typical design values of the thickness of the thermal insulation material when they are put into production and in the case of making changes to the design of the prefabricated system, using new materials of thermal insulation and/or finishing layers, when the technology of their production changes. The article presents the results of testing experimental samples of insulating products with non-ventilated air layers. A comparison of the results with normative indicators of compressive strength, bending strength, impact strength, water absorption and frost resistance was analyzed. Extruded polystyrene has a much higher compressive strength than Styrofoam. The high strength of extruded polystyrene foam is its main advantage and allows it to be used not only as insulation, but also as a building material that sometimes even performs the functions of auxiliary or load-bearing structures. Polymer sand tile, having lower indicators of thermal resistance, achieves high operational indicators, which will allow it to be used for insulation of plinths.
