精钢覆膜彩钢瓦为什么隔热效果好？

覆膜彩钢瓦屋面保温材料常用于屋面保温，但很多人不知道什么是屋面保温材料。市场上有很多种屋顶保温材料。我们来比较一下各种屋顶保温材料的导热系数
1彩钢瓦：导热系数41w/MK
2岩棉板：导热系数41w/mk-45w/mk

Roof insulation materials are often used in roof insulation, but many people don't know what kind of roof insulation materials are. There are many kinds of roof insulation materials on the market. Let's compare the thermal conductivity of various roof insulation materials

1. Color steel tile: thermal conductivity 41w / MK
2. Rock wool board: thermal conductivity 41w / mk-45w / MK
3. The thermal conductivity of synthetic resin tile is 11.63 w / M.K
4. Coated steel tile: thermal conductivity, as low as 2.93w/m.k
Are you very curious about the reason why the thermal conductivity of the coated steel tile is so low? The answer is now revealed to you
As the independent research and development of Jiangsu Payne new materials Co., Ltd., Jinggang coated tile adopts new concept and technology, uses high-strength special steel plate as base plate, and laminated composite anti-corrosion and thermal insulation composite materials on the front and back sides, realizing the combination of high-efficiency heat insulation and long-term corrosion protection at the same time.
The silverreflection coefficient of coated steel tile is as high as 81%, which can effectively reflect light and heat. At the same time, the thermal conductivity of fine steel coated tile composite is very low, as low as 2.93w/m.k, while that of color steel tile steel plate is 41w / M.K. Benefited from these two properties, the coated steel tile has excellent heat insulation performance. Compared with the same period of the same period, the temperature of the standard type factory building with color steel tile can drop more than 8 ℃ in high temperature weather.
