Novel external thermal insulation system for external wall

Abstract

The invention discloses a novel external thermal insulation system for an external wall. The novel external thermal insulation system sequentially comprises a base body, bonding mortar, an interface agent, plastering mortar, glass fiber gridding cloth and an external wall facing system from inside to outside, wherein a blocky rock wool belt is arranged between the interface agent and the plastering mortar, and the fiber direction of the rock wool belt is perpendicular to the base body. According to the novel external thermal insulation system, a traditional rock wool board structure is arranged to be the blocky rock wool belt, equipment such as a bracket is not needed during installation, the tensile strength is greatly improved, and the safety performance is 15 times or above that of a rock wool board system; and in addition, due to the fact that the fiber direction of the rock wool belt is perpendicular to the base body, bulging and cracking can be effectively prevented, the air permeability and the respiration are better, and the water seepage problem of a rock wool board wall body is effectively solved.

Description

technical field [0001] The invention relates to a novel external wall thermal insulation system, which belongs to the technical field of energy-saving and environment-friendly building wall thermal insulation. Background technique [0002] At present, most of the rock wool insulation systems on the market are rock wool board systems. The surface tensile strength of rock wool boards is generally only about 7.5kPa, which is far lower than the technical regulations for external wall insulation engineering (JGJ144-2008) for The insulation material requires 100kPa, and the rock wool board is bulky and heavy. Metal brackets are required during construction. After construction, there are drums and cracks. Not only the air permeability and breathability are not good, but also there is water seepage. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a new type of external wall insulation system to facilitate the instal...
