Rock wool pipe, glass wool and polyurethane foam and other materials, and they each have their own advantages and disadvantages. The advantages of rock wool are mainly in the price, very cheap, but the temperature resistance is poor, and low environmental protection. Glass wool has good thermal insulation, but compression resistance is not good, and polyurethane foam, if the sealing effect is good, compression resistance is also good, is the temperature resistance is relatively poor.

How to choose the external wall insulation material?

1, in the purchase, the first thing to pay attention to look at its thermal insulation performance. And also to choose the thermal conductivity of small, both to meet the construction requirements, but also in the construction of convenient, in order not to increase the difficulty of construction. At the same time, but also look at the thermal insulation effect of the material, if the insulation is not good, the room will feel very hot, affecting the living effect.

2, for this material, but also to choose a good insulating material, not only thermal insulation, there is a fire function, in the construction of the building can guarantee the safety of the building. At the same time, it is also necessary to take into account the water absorption rate. Because as an exterior wall material, easy to contact with rain, if the water absorption rate is high, it is easy to absorb moisture, will increase the thermal conductivity, so be sure to choose a low water absorption rate of the material.

3, in general, low-density materials can reduce the load and facilitate the construction of the exterior wall, so you can not ignore this when buying materials. And we need to take into account the convenience of construction and maintenance when buying insulation materials, because the construction of external walls is a difficult job, if the material is not good construction, it will affect the entire construction progress.
