Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of roofing construction, in particular to a roofing heat insulation and waterproof construction method. BACKGROUND

[0002] Roofing is the outermost peripheral component of a building, used to resist the influence of natural factors such as rain, snow, wind, frost, solar radiation, and temperature changes, to ensure a good use environment inside the building. The roofing should meet the functional requirements of being solid and durable, waterproof, heat-insulating, heat-insulating, fireproof, and resistant to various adverse effects, so that the roofing has the functions of heat insulation and waterproofing.

[0003] A roofing heat insulation and waterproof construction method is disclosed in a Chinese patent (Grant Announcement No. CN112177249A). The construction method includes: treating the roofing panel base layer; setting a bonding layer on the roofing panel base layer; laying a foam glass plate layer on the bonding layer; laying a cement mortar layer on the foam glass plate layer; and constructing a waterproof layer on the cement mortar layer. However, the above method uses a bonding layer, a foam glass plate layer, a mortar layer, and a waterproof layer for heat insulation and waterproofing. This method has little difference in heat insulation and waterproofing performance from the market, and the heat insulation and waterproofing performance is not high.
