With the continuous improvement of building performance and safety requirements, new thermal insulation materials have become an indispensable part of buildings. We want to live in a house that not only saves energy, but also saves engineering costs. The board not only has the function of heat preservation and energy saving, but also has the performance of fire prevention and sound absorption. In this way, our living environment is safe and guaranteed, and will not cause great loss of life and property due to the fire of children playing. Don’t worry about the noise of your residence, the rock wool board on the outer wall can help you solve these problems.
Rock wool board of exterior wall is made of basalt outer wall rock wool board. Rock wool pipe is a kind of shell made of various processed products. It is widely used in construction, industrial equipment, shipping and other industries, which makes the demand of rock wool board of external wall rising. Therefore, we need to know more clearly what a good exterior wall rock wool board looks like! Next, I will share with you our experience in selecting the quality of external wall cotton board.
First of all, we should understand the characteristics of high-quality rock wool board.
1. The thermal conductivity is low, and the thermal conductivity is an important index to measure the performance of the rock wool board. The smaller the thermal conductivity is, the less the energy transferred through the material is, the better the insulation performance of the rock wool board is.
2. The sound absorption coefficient is high. The sound absorption effect of rock wool board for thermal insulation exterior wall mainly depends on the density of rock wool board per unit area. The higher the density, the better the sound absorption effect.
3. The outer wall rock wool board has low water absorption rate, and the insulation effect will be greatly reduced due to the high thermal conductivity of water.
It must have a high weight to support the exterior wall.
With the rapid development of external wall rock wool board, national building energy saving policies and regulations have been vigorously promoted. In order to replace high cost, low safety factor of non renewable natural stone. Building energy conservation has become one of the key points of the world’s construction technology development, and then observe whether the external wall rock wool board slag is qualified, there is not much slag in the external wall rock wool board. The exterior wall rock wool board has smooth appearance, no stain and no damage, and the amount of glue is very uniform. If you touch it with your hand, it will feel very thin. Another thing is to see if the color is the same. If there is a difference between white and yellow, it is a poor product.
High quality rock wool board has good insulation, sound insulation, insulation effect, convenient construction, at the same time, it also 8 responds to the policy of the national environmental protection department, improves the energy saving effect, and is a practical external wall rock wool board insulation material. There are many ways to select rock wool board for fire-resistant exterior wall. For professionals, as long as the color distribution is uniform, it is easy to distinguish the quality. According to the data provided in the public data sheet of buildings, the weight of rock wool board for standard exterior wall is 120-130 kg / m2, and the quality of thermal insulation materials is directly related to our health and safety.
