Glass wool insulation felt is non-combustible, nontoxic, and resistant to corrosion; it has low moisture rate and good hydrophobicity. It is to date a well-recognized heat preservation, thermal insulation and sound absorption material with excellent properties.
aluminum foil can be applied to the surface as decoration and means of preventing moisture and radiation protection.
