1、一般有三种方法：
1. There are generally three methods:
1、在下面做隔热层也就是保温层。
1. Make a thermal insulation layer below, that is, a thermal insulation layer.
2、可以在上面做斜屋面隔热。
2. The inclined roof insulation can be made on it.
3、在彩钢瓦上使用反射涂料隔绝夏天的热量。
3. Reflective coatings are used on colored steel tiles to isolate the heat in summer.
2、彩钢板屋顶用隔热砖不行，只能用隔热涂料，可以试着用果尔佳4012和4022隔热王涂料，施工比较简单，只要喷涂在彩板表面就可以
2. Thermal insulation bricks can't be used for color steel plate roof. Only thermal insulation coatings can be used. You can try to use guoerjia 4012 and 4022 thermal insulation King coatings. The construction is relatively simple, as long as they are sprayed on the surface of color plate
有一种非常简单、经济而有效的方法，即在安装屋面彩钢板之前，在板条上面铺上一层双面反射箔薄膜，这样不仅可以使蒸汽隔离，还能起到减少水分热量的凝聚作用。
There is a very simple, economical and effective method, that is, before installing the roof color steel plate, lay a layer of double-sided reflective foil film on the lath, which can not only isolate the steam, but also reduce the condensation of water and heat.
如果这层薄膜能在彩钢板的板条之间的下垂深度达到50~75mm，那么薄膜与屋面板之间的空气层将进一步提高隔热效果。
If the sagging depth of this film between the slats of color steel plate can reach 50 ~ 75mm, the air layer between the film and the roof panel will further improve the thermal insulation effect.
其中彩钢板的冷暖色系以及它的漆面反射能力都和辐射有关。真正进入建筑物的热量就是因为辐射，其进入热量的比例多少将取决于彩钢板下表面的特性。下表面带漆或暗色的彩钢板，将有较高的反射能力，可将留下的热量大幅度的辐射进去，而下表面带闪亮的或磨光表面的彩钢板发散力很低，只能将很小一部分热量辐射进建筑物中。
The cold and warm color system of color steel plate and its paint reflection ability are related to radiation. The real heat entering the building is radiation, and the proportion of the heat entering the building will depend on the characteristics of the lower surface of the color steel plate. The color steel plate with paint or dark color on the lower surface will have high reflection ability and can greatly radiate the left heat, while the color steel plate with shiny or polished surface on the lower surface has low divergence force and can only radiate a small part of the heat into the building.
