Inorganic sandwich composite external thermal insulation system

Abstract

The invention discloses an inorganic sandwich composite external thermal insulation system and a construction technique thereof. The inorganic sandwich composite external thermal insulation system comprises a foundation wall, wherein the border periphery of the foundation wall is orderly provided with an inorganic light-weight aggregate thermal insulation mortar bonding layer, an inorganic fiber cotton heated board layer and an inorganic light-weight aggregate thermal insulation mortar bonding and leveling layer, and an anti-cracking protective layer and a coating facing layer are orderly arranged outside the inorganic light-weight aggregate thermal insulation mortar bonding and leveling layer. The construction technique comprises the following steps: after wall face base layer treatment and border mortar treatment, sticking inorganic fiber cot ton heated boards with adhesive inorganic light-weight aggregate thermal insulation slurry, leveling the slurry surface layer by attaching inorganic light-weight aggregate thermal insulation mortar, and finally, constructing the anti-cracking protective layer and the coating facing layer. The fire-protection rating of the inorganic sandwich composite external thermal insulation system achieves non-combustible type; and the invention has the advantages of weather fastness and air permeability.

Description

technical field [0001] The invention belongs to the thermal insulation structure of building walls, and in particular relates to an external thermal insulation system for external walls of an inorganic fiber cotton thermal insulation board sandwiched by inorganic light aggregate thermal insulation mortar. Background technique [0002] With the intensification of the world's energy crisis and the further deterioration of the ecological environment, the contradiction between my country's energy and environmental protection issues has become more prominent due to the continued rapid economic development. The impact of building insulation and energy conservation on the ecological environment has attracted the attention of the industry, requiring building exterior walls to be done For the insulation layer, the amount of insulation materials used will be surprisingly large, which will not only consume a lot of resources, but may also cause new environmental problems. Building therm...
