DEVELOPMENT OF THERMAL INSULATION TILE WITH NON-VENTILATED AIR LAYERS SHIELDED BY FOIL MATERIAL

Abstract

 A heat-insulating tile consisting of a back, side and front wall made of extruded expanded polystyrene and a polymer-sand mixture has been developed. Inside there are two unventilated air layers, separated by a heat-reflecting screen. In order to exclude cold bridges, the thermal insulation tile is made of two parts, offset in the horizontal direction. Fixing of tiles among themselves is carried out by means of occurrence of ledges on the top face of one tile with hollows on the bottom face of another. This type of joining plates ensures the absence of cold bridges and facilitates their installation. The problem is solved by the fact that in the facade thermal insulation panel containing the front, rear walls, side faces and locking elements in the form of protrusions and recesses arranged in a checkerboard pattern, and made with the possibility of mounting, the front and rear walls form a frame with a cavity , filled with insulating material, characterized in that the locking elements are placed on the front faces of the frame. Shielded layers of air are used as heat-insulating material. The frame of the panel is made of polymer-sand material, and for its fastening use an adhesive solution. This is achieved by making a panel of polymer-sand frame, in the middle of which there are shielded air layers, which provide resistance to heat transfer and infrared radiation of the material.
