Since people have studied floor heating, everyone’s quality of life is getting better and better, but the quality of insulation materials on the market now varies greatly. When you buy floor heating, you may buy poor-quality insulation materials. Now teach you how to avoid poor quality Can you buy good-quality floor heating and insulation materials?
1. Look at the cut surface of the material
There are dense and fine particles on the cross section of the insulation board. The finer the particles and the cleaner the cross section, the better the quality of the insulation board. The fine particles mean that the thermal conductivity of the thermal insulation board is very low and the thermal insulation effect is good; the cleaner the cross section, it means that there are no impurities and the raw materials are pure.
2. Look at the color of the material
The color of 100% brand new extruded board should be white. Most of the material boards on the market have colors because of the addition of color masterbatches. In general, the more positive the color, the better. Colored material boards have no effect, but the color of inferior extruded boards is gray, black and dark.
