What are the main methods of roof insulation and cooling?

Thermal insulation and cooling methods;

1, with heat insulation and ventilation structure.

Thermal insulation ventilation is to set ventilation interlayer on the roof, and the surface of the roof plays the role of shielding sunlight. The ventilation interlayer uses heat and wind pressure to continuously flow away the hot air between the interlayers, thus reducing and transferring the hot air to be transferred indoors, and achieving the purpose of thermal insulation and cooling.

2. Adopt the method of planting plants for heat insulation.

When planting plants on flat roofs, firstly, the cultivated soil and plants are used for heat insulation, and secondly, the transpiration and photosynthesis of vegetation are used to absorb and transfer the radiant heat of the sun, so as to achieve the purpose of heat insulation and cooling. However, this kind of planting insulation roof structure needs to be equipped with retaining walls.

3. Adopt water storage structure method to keep warm.

The practice of water storage structure is to store a layer of water with suitable depth on the roof. When using water to evaporate, it needs a lot of vaporization heat and consumes a lot of solar radiation heat, thus reducing the heat absorbed by the roof and achieving the purpose of cooling and heat insulation. The structure of water storage roof is basically the same as that of rigid waterproof roof, except that three holes are added to one wall, namely, water storage compartment wall, overflow hole, drainage hole and overflow hole.
