Sound insulation felt
Aluminium thermal insulation felt
Reflecting insulators are products deriving from NASA technology for space programs.
They are thermoacoustic insulators, not so thick, that can be used for any application and that have their best performances when they reflect 97% of the heat transmitted by radiation.
Reflecting insulators are composed of polietylene film melted on aluminium sheets; in fact the thermoacoustic action is due to this type of polished surfaces. They are reflecting materials and consequently they absorb a low percentage of sun radiation and thermal radiation and also they give out a low percentage of them.
It means that a reflecting material, placed inside an air cavity, reflects without absorbing the great part of the radiating energy that hits it. Just in case of a cavity not exposed directly to sun rays, this is only infrared energy of thermal type.
Use: heat insulation and soundproofing for walls, roofs and floors.
