As the name implies, the insulation board is the heating of the building. By laying the insulation board on the outer wall and the roof, it can play a good role in heat insulation. So, what are the types of roof insulation boards? What are the characteristics of the thermal insulation board? Today, I will talk to you about the type of roof insulation board.
1 polyurethane insulation board
It is one of the most common and widely used thermos. It has a low heat conduction coefficient and good thermal work performance. Its specific thermal conductivity is only 0.018g ~ 0.023W/(M.K). It is currently the lowest thermal conductivity in all thermal insulation materials. It also has the ability to prevent moisture -proof and waterproof, with a closing rate of up to 90%, which can effectively prevent the water seepage of the wall. Not only that, it also has excellent fire prevention, flame retardant, and high temperature resistance, and it will not produce harmful gases due to high temperature, which is very safe to use.
2 Cement foam insulation board
It is mainly produced by cement and flour ash, which is produced by bubbles through some auxiliary materials. It has very prominent fire resistance, and the fire level can meet the A1 standard. Its service life can even be the same as the building, and its quality is very light, which has greatly reduced the weight of the wall. There are also good performance in sound insulation and heat insulation. The sound insulation effect is more than 5 times that of ordinary cement, and the thermal insulation temperature is as high as 400 ° C.
3 Expansion polystyrene board
The expansion polystyrene board is referred to as an EPS board, which is called polystyrene foam board. It is a white solid with a fine and closed -hole structure and has excellent thermal insulation effect, but there is also a disadvantage that it is easy to absorb water and affect its own quality. Therefore, it must be done well for waterproof measures. This type of insulation board is relatively complicated in construction. It is troublesome to add grid cloth in advance.
4 extrusion plate
The extrusion plate is referred to as XPS board, known as the squeezing polystyrene foam board. It is a foam foam plastic plate made of polystyrene resin and polymer through the action of catalyst. It has a hard texture and has strong hardness and impact resistance. There are also outstanding performance in the insulation capacity.
