Description

Building exterior wall insulation system

Technical Field

The present application relates to the technical field of thermal insulation systems, and in particular to a thermal insulation system for building exterior walls.

Background technique

The background of the building exterior wall insulation system can be traced back to the oil crisis in the 1970s. At that time, the world oil price rose and the country began to pay attention to energy conservation and utilization. Building exterior wall insulation is considered to be one of the important means of energy conservation and environmental protection. The building exterior wall insulation system improves the thermal insulation performance of the building wall by adding insulation materials to the surface of the building exterior wall, reduces energy loss, and thus reduces heating and cooling energy consumption. At the same time, the exterior wall insulation system can also improve the indoor comfort of the building, improve the frost resistance of the wall, and extend the service life of the building. The building exterior wall insulation system has become an important means of building energy conservation and is widely used in various types of buildings.

The external wall cold and hot bridge insulation system mentioned in the existing Chinese public patent authorization announcement number: CN207878676U, the external wall is fixedly connected with a leveling layer, and the rock wool layer, the insulation layer and the fireproof layer are sequentially adhered to the leveling layer through polymer mortar; a sound-absorbing board is buckled on the fireproof layer, and a number of clips are vertically arranged on both sides of the leveling layer. The side of the sound-absorbing board close to the wall is fixedly connected with an angle steel, and the inner right angles of the angle steel face the two sides of the sound-absorbing board respectively, and the angle steel and the clip are detachably connected. Since the rock wool layer, the insulation layer and the fireproof layer are fixed by locking the sound-absorbing board with the clip, the cold and hot bridge effect between each layer and the external wall is eliminated, so that this wall insulation system has the advantage of good insulation effect.

When installing the existing building exterior wall insulation system, the fasteners need to be lifted first and then the insulation layer is placed on the fasteners.
