Roof heat insulation method

Abstract

The invention discloses a roof heat insulation method. The roof heat insulation method includes the following construction steps: (1) paving a leveling layer formed by cement mortar on a floor of a roof; (2) after the leveling layer is dried, uniformly coating the leveling layer with a waterproof layer; (3) dividing the waterproof layer into a plurality of cells, enabling area of each cell to be less than 16m<2>, and reserving an expansion gap between every two adjacent cells; (4) after the waterproof layer is solidified, uniformly paving a protective layer on the waterproof layer, and paving white ceramic tiles on the protective layer; (5) controlling gaps among the white ceramic tiles in each cell within 3mm, filling the gaps with white cement, and filling the expansion gap between every two adjacent cells with white glass cement. By the aid of the method, indoor temperature of a top floor of a building can be effectively prevented from rising, heat insulation effect is obvious, and the indoor temperature of the top floor of the building is basically equal to that of other floors.

Description

technical field [0001] The invention relates to a roof heat insulation method. Background technique [0002] In summer, the sun is strong and the weather is hot, especially for residents living on the top floor, the temperature will be higher, which is particularly uncomfortable. Nowadays, a heat insulation layer is often installed on the roof. Now some buildings use bricks such as cement bricks, square bricks or rectangular fire bricks for heat insulation. These bricks are usually darker in color and easy to absorb heat. It is an object that absorbs heat quickly and dissipates heat slowly. When the sun shines on the cement bricks of the heat insulation layer, it will absorb a lot of heat energy, which will heat the floor instead, making the floor temperature higher and the heat dissipation time longer, affecting the heat insulation of the roof. Without the expected insulation effect, the temperature on the top floor of the building will rise very high. In addition, these ...

Problems solved by technology

But these insulating coatings are easy to fall off, have poor durability, and can emit a kind of unpleasant smell under the irradiation of sunlight, so that the air quality on the roof will not be very good, which will affect people's activities on the roof
