Thermal insulation and decoration integrated board, external thermal insulation system and construction method

Abstract

The invention discloses a thermal insulation and decoration integrated board which comprises a thermal insulation layer and a facing layer. The facing layer is provided with supporting grooves and step grooves. By the application of the thermal insulation and decoration integrated board, the structure of an external thermal insulation system can be more simplified, production and construction cost can be lower, the connection strength with a wall base can be higher, installation and construction can be convenient and fast, the internal and external cold and hot bridge phenomenon can be small, and the waterproof effect can be good. The invention further discloses the external thermal insulation system and a construction method of the external thermal insulation system.

Description

Technical field [0001] The invention relates to the technical field of building materials, in particular to a thermal insulation and decoration integrated board, an external wall thermal insulation system and a construction method. Background technique [0002] my country's building energy consumption accounts for about 30% of the country's total energy consumption. Building energy conservation is a very important task to alleviate my country's energy shortage, improve people's living and working conditions, reduce environmental pollution, and promote sustainable economic development. Building energy conservation mainly includes three parts: building roof thermal insulation, building exterior maintenance wall and exterior doors and windows thermal insulation, and building equipment energy saving. In October 2007, the state issued a document requiring that new buildings across the country must be thermally insulated, and existing buildings also require energy-saving renovation wit...
