There are three main types of widely used exterior wall insulation technologies: 1. Exterior wall internal insulation, 2. Exterior wall self-insulation, 3. Exterior wall external insulation.
Glass fiber mesh cloth exterior wall internal insulation technology is not only economical but also a relatively simple wall insulation technology, but it also has some disadvantages:
1. The cold and hot bridges in the beam and column parts are not very well handled.
2. The required thickness of the insulation layer is relatively large, which will occupy the practical area of the building.
3. It will have some impact on the second decoration, bring some inconvenience to some hanging facilities, and when problems occur, the maintenance will have a greater impact on the residents.
At present, the glass fiber mesh cloth exterior wall internal insulation technology has gradually been replaced by other forms of insulation technology, and some high-rise buildings' insulation is no exception.
Glass fiber mesh cloth exterior wall self-insulation technology is a structural insulation technology, and many places are now exploring and promoting it. Glass fiber mesh cloth exterior wall self-insulation is relatively convenient from the initial design to the later construction form. However, from the perspective of seismic resistance and shear resistance design of high-rise buildings, the promotion value is relatively limited, and the difficulty of cold and hot bridges of beams and columns is also relatively large. Using temperamental energy-saving bricks to fill the wall for painting is also a problem. Preventing wall cracks will appearing in the glass fiber mesh cloth exterior wall self-insulation technology. Moreover, this technology also has many disadvantages, such as water seepage and easy detachment of the decorative layer. Relatively speaking, the glass fiber mesh cloth exterior wall self-insulation technology needs to be developed and innovated.
Glass fiber mesh cloth exterior wall external insulation technology is a relatively ideal glass fiber mesh cloth wall insulation energy-saving technology in terms of thermal efficiency and improving the stability of the temperature difference of the wall structure. It is the best solution for the thermal insulation of shear walls in high-rise buildings. Especially when the national energy-saving standard is raised from 50% to 65%, the limit value of the external wall heat transfer coefficient is reduced to a lower level. For this reason, the design and rationality of the glass fiber mesh external wall insulation technology are more important. These characteristics of the glass fiber mesh external wall insulation technology can meet the construction requirements.
