Outer wall insulating board and mounting method thereof

Abstract

The invention discloses a thermal insulation board for an outer wall, which comprises a thermal insulation layer and an interface layer, and the thermal insulation layer adopts inorganic fiber cotton. The important feature of the present invention is that the fiber orientation of the inorganic fiber cotton is perpendicular to the interface layer and the wall surface. This makes the drawing direction of the inorganic fiber cotton parallel to the direction of the wind and the direction of the force after installation, which improves the tensile and compressive strength and resists the damage to the wall caused by the wind pressure.

Description

Technical field [0001] The invention belongs to the technical field of thermal insulation material structures for buildings, and in particular relates to an external wall thermal insulation inorganic fiber cotton composite wall board and an installation method thereof, which has the comprehensive performance of thermal insulation and waterproofing. Background technique [0002] External wall insulation is one of the important measures for building heat preservation and heat insulation. Some external wall insulation materials use foam materials, of which polyurethane rigid foam is the most, although polyurethane foam has caulking, bonding, sealing and heat insulation , Sound absorption and many other effects, it is an environmental protection and energy saving, easy to use and put building materials. However, since the foaming rate of polyurethane foam will be reduced at a temperature below 10°C, it will be restricted by the season when used. Secondly, because the polyurethane foa...

AI Technical Summary

Problems solved by technology

Practice has shown that due to the compressibility of fiber cotton, such a structure has relatively weak tensile and compressive capabilities.
