Roof Thermal Insulation Foamed Concrete

Shenzhen foam roof insulation layer is the use of concrete, mortar or cement mortar joined bubbles, bubbles mortar or cement mortar made from, and then in the roof construction, one obtained by curing and hardening and roof insulation layer, became a part of the roof. their structure is as follows.
1. waterproof crack resistance of concrete surface layer: this layer is waterproof crack resistance of concrete, 20~30 mm thickness.
2. pour in place foam concrete insulation layer: the insulating layer is made from cement and foam, 400~700 kilograms per cubic metre, 0.1~0.2W/m.k thermal conductivity, thickness 30~300 mm. it is the subject of the structure layer, depending on its function of thermal insulation of the building.
3. waterproofing: waterproofing layer can be made of flexible waterproof material, since the protection of foamed concrete, it may live for 50 years or more.
4. the roof slab and the concrete floor: must have structural layer of concrete on the floor and not have a gap. the construction of the roof should be repaired first.
Advantages of foam concrete insulation roofing
1. good heat preservation effect of foam concrete, situ foamed concrete thermal resistance is 5~10 times normal overhead insulating bricks, with 60 mm thick insulation layer of clods of soil in fire roasted for 20 minutes, do not seem hot on the back. its thermal insulation effect.
2. cost less than brick and insulation Board: casting heat insulation layer of lightweight foam concrete cost less than traditional ceramic perlite insulation is other insulation cost 40%~60%. only about 5~12 Yuan per square meter.
3. bubble concrete process simple, more easy forming, construction speed fast than other roofing insulation method can save construction costs 60%. each Taiwan class can completed 500~800 square meters, construction speed soon. Dang instead of structure find slope Shi, both can save engineering cost, and can avoid structure find slope and appeared top layer smallpox beam Board tilt phenomenon, only must by slope to with ruler wipe flat.
4. protection of roof and prevention of deformation cracks of roofing structure foamed concrete roofing will not crack due to temperature changes, can effectively prevent (a) roof structure and roof structure with temperature crack in the brick wall at the junction of disease occurrence.
5. foam concrete extends waterproof roof life, strengthening effect, foam and waterproof layer (or layers) close to the body, which can effectively prevent the roof structure caused by the expansion and contraction (or rigid waterproofing layer) deformation and cracking and leakage phenomenon, and can effectively prevent the ageing of waterproofing materials, prolong life and strengthen the effect of the waterproofing layer.
