Product Description

Aluminum foil +bubble +aluminum foil description: our single bubble double foils insulation material are made of one layer low heat conductivity bubble film sandwiched between two low emissivity aluminum foil 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 40 m thickness 3.2 mm diameter 40 cm coverage 48 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
