Product Description

aluminum foil +bubble +pe description: our single bubble single foil insulation material consists of one layer high reflective 97% aluminum foil and one layer low heat conductivity bubble film . working principle: 1. high density 99.4% pure aluminum foil can reflective 97% radiant from the sun 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 8.64 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
