Ke Debang insulation reflective film layer by the anti-aging metal foil layer + + + fiber composite layer by layer made of hot-melt laminated composite technology. Is a highly efficient thermal insulation products. It is based on the low emissivity of aluminum foil to achieve the thermal insulation effectiveness.
"Kede Bang" insulation used in the anti reflective film layer can effectively reduce the damage of UV on the material, which compound in the metal foil on top of aluminum foil can be used to ensure a good life, and the middle of the composite layer can make a good metal foil attached to the bottom fiber layer, so that the material to better meet the construction requirements.
principle:
heat transfer in heat exchange performance of buildings in three ways: conduction heat + convection heat <25% of radiant heat> 75%.
summer temperature tile roof, a large number of radiation heat into the room caused the temperature continues to rise, work and living environment extremely uncomfortable.
barrier film solar radiation absorption coefficient of 0.03, very little heat radiation. Are widely used in roof and wall insulation.
energy transmission line (without the barrier film): sunlight - infrared magnetic waves - to heat shock temperature tiles - tiles radiate heat energy into heat - heat shock Cast the temperature rise roof - the roof into place radiate heat energy - the indoor temperature continues to rise
energy transmission line (plus barrier film): sunlight - infrared magnetic waves - to heat shock temperature tiles - tiles radiate heat energy into heat - heat shock aluminum foil surface & mdash ; - aluminum foil emits very little heat to maintain a comfortable indoor temperature
