Please do something for me. The effect is obvious if the roof is insulated, hehe.

The flat roof in hot climate area should be provided with insulation layer. The common method is to erect 1 layer of large-area bricks or cement slabs on the roof surface, that is, on the waterproof and drainage layer of the roof, to form a ventilation and thermal insulation layer, and take away a lot of heat by using the flow of air in the thermal insulation layer. Another way is to set a solid insulation layer on the roof surface, that is, to accumulate materials with large thermal storage coefficient on the roof surface to absorb solar radiation heat, such as laying large bricks, concrete slabs, piling soil, gravel, cinder and slag. You can also set up reservoirs and swimming pools on the roof surface of flat roofs to plant flowers, trees and so on.

The top insulating layer is usually made by the above two processes:

(1) gypsum board ceiling is lined with thermal insulation board or thermal insulation cotton;

(2) The ceiling of the sweater board (sauna board) is lined with thermal insulation board or thermal insulation cotton;

First, heat insulation board or thermal insulation cotton is fixed on the top of the building or above the ceiling.

Attic insulation is mostly done by decoration companies, and the quotations are different according to different materials (decoration price: for reference only);

1, the price of ordinary thermal insulation cotton plus gypsum board (veneer) cover is usually 60-70 yuan;

2. The cover quotation of ordinary thermal insulation cotton plus board fir board (sauna board) is usually 85- 100 yuan;

3. The use of advanced insulation board base is more than the ordinary quotation 10- 15 yuan.

The light steel keel at the grass-roots level should be treated with anticorrosion.
