How to do roof insulation

1. base cleaning: sundries and dust should be removed from the surface of the thermal insulation wall to be laid to ensure the stability and thermal insulation effect of the thermal insulation layer.

2. Finding slope by elastic line: according to the slope of the wall and the direction of running water, find out the slope direction of the roof, determine the thickness range of the insulation layer, ensure the volume of the thickness range, and prepare stone.

3. Fixation of pipe root: The pipe root passing through the structure should be treated before the insulation layer construction, and it is best to block it with fine stone concrete.

4. Gas barrier construction: After the completion of 2-4 procedures, the roof with gas barrier requirements should be designed as a gas barrier, and the coating should be painted evenly, without leakage, and the coating is not easy to be too thick, so it is best to level it.

5. Laying of thermal insulation layer: the plate-like thermal insulation material is horizontally bonded to the roof base with bonding material, generally with cement-lime mixed mortar (there is concrete specially used for thermal insulation in the market); The polystyrene board material should be bonded with asphalt cement.

6, leveling layer: If you want to pursue beauty, you can decorate some tiles on the surface.
