Product Description

aluminum foil + bubble + epe + bubble + aluminum foil description: our double bubble double foils insulation material are made of one layer low heat conductivity epe foam sandwiched between two layers bubble film and two low emissivity aluminum foils. working principle: 1. when the radiant from the sun touch the things , the heat will be reflective back , or absorb or transmit into the house . high density 99.4% pure aluminium foil can reflective back 97% radiant from the sun , only 3% radiant be transmit . which ensure a perfect and comfort summer and winter living condition . 2. uncontinuous and never flow air stay in the air bubble cell can slow down the heat conduction and block heat convection . so it will not be unaffected by humidity and ensure the best living condition both in extreme hot and cold climate . technology data: technology data item data unit width of roll 1.2 m length of roll 20 m thickness 10 mm diameter 50 cm coverage 24 m2 weight 11.04 kg temperature: -50? to 80? emissivity 0.03 reflectivity 97% linear shrinkage none corrosion none fungi resistance no growth water vapor permeance:100% waterproof aplication: 1. can works well works well in both extreme cold and hot climate, 2. used in roof, wall, ceiling, floor , attics, ,pole barn, crawl space, wall system, basement, garage, freezer, air-condition pipe, 3. suit for new and old building structure , benefit: 1. r-value can reach 7.9 , different heat flow direction has different r-value 2. double sides of pure aluminum foil (99.4%) ,can reflective 97% radiant , allow only 3. uncontinuous air cell , can slow down the heat transfer and block the heat convection 4. the material can not burnself ,and not support burn , fire-resisting rate:class a 5. it will not absort any water ,be unaffected by the humidity and moister . 6. be cut easily(knife) ,be fixed conviently (paste, staple ) ,diy by yourself 7. lighter and thinner, will not be the burden of the construction, good for new and old building 8. do not become mildewed, incorruption (pure aluminum foil ) 9. non-toxic, recycled materials, rescyle, environmental 1. keep cool and dry in summer ,keep warm and dry in winter
