Description

Vacuum insulation and thermal insulation systems for buildings

technical field

The utility model relates to the thermal insulation field of building energy-saving external walls and roofs, in particular to a vacuum thermal insulation layer and thermal insulation system for buildings.

Background technique

As my country's building energy conservation is gradually advancing towards the energy-saving rate of 75%, the conventionally used organic insulation materials and their external wall insulation systems (such as: molded polystyrene board, extruded board, polyurethane board and phenolic board and other organic insulation materials and its external wall insulation system) to achieve this technical index, it is necessary to increase the thickness of the above-mentioned insulation material and the length of the fixing parts, so it will increase the load on the external wall and foundation of the structure; in addition, because the above-mentioned insulation materials are organic and the combustion level They are all Class B, so the construction of the building vacuum insulation layer composed of it must be equipped with a fire protection zone with a combustion grade of A class. The second is that it will increase the risk of cracking and hollowing at the joint between the insulation layer and the fire protection belt, and the third is that it will significantly increase the comprehensive cost of the building energy-saving insulation project.

It is not difficult to see from this that the new situation of building energy conservation requires the continuous emergence of new thermal insulation materials and new processes in order to ensure the realization of the ambitious goal of energy saving rate of 75%.

At present, most of the thermal insulation treatment of the lap joints of the skirts of building insulation panels and the thermal insulation treatment of the side walls of doors and windows used in the market is the construction method of smearing vitrified microbead thermal insulation mortar [this kind The thermal conductivity of thermal insulation mortar is ≥0.07 W/(m.k)], however, the thermal insulation performance of thermal insulation mortar such as vitrified microbeads does not match the thermal insulation performance of thermal insulation boards. Therefore, the thermal insulation performance of the entire thermal insulation system cannot be consistent. In the end, it will inevitably lead to large-area condensation and even mildew on the walls of the thermal insulation project in winter. It will not meet the requirements of the existing energy-saving indicators, let alone achieve the energy-saving rate of 75%.

According to investigations, most of the thermal insulation projects that adopt the construction method of vitrified microbeads and other thermal insulation mortar are unsuccessful. A high-rise affordable housing building in a certain city, due to the adoption of this construction method, the thermal performance of the thermal insulation project failed to meet the design And completion acceptance requirements, was listed by the Municipal Construction Committee as a typical case of unqualified building energy conservation projects.
