Material :
Pure Aluminum Foil: High density 99.4% aluminum foil , lighter and shiner, can reflect 95-97%Heat Radiant , it is the best heat insulation material .
Polyester Film : Good Tensile ,water proof, anti-oxygen,insulation , oxidation resistance,High resistance .
PE Bubble film :water-proof , moister , no condensation,sound-proof,soft,easy to install .
3Working Principle:
Warm in Winter and cool in summer
High Density 99.4% pure aluminium foil can reflective 97% radiant heat from the sun
uncontinuous and never flow air stay in the air bubble cell can slow down the heat conduction and block heat convection
it will not be unaffected by humidity and ensure the best living condition both in extreme hot and cold climate .
