Features of polyethylene foam insulation board

 

The polyethylene foamed thermal insulation board has a closed-cell structure. It is based on the heat insulation of the gas in the closed cells instead of the polyethylene material. It has excellent resistance to water vapor penetration. The built-in vapor barrier is both a thermal insulation layer and a vapor barrier, without the need for a separate vapor barrier. The value of the moisture resistance factor is much larger than other insulation materials, which can effectively prevent the occurrence of condensation.

Polyethylene foam insulation has good fireproof performance. There are two types of high-grade insulation materials, which are ordinary type, flame retardant type (oxygen index ≥27), and flame-resistant type (oxygen index ≥32), which can meet different fire protection requirements. And this product has the smallest smoke toxicity among the existing foam insulation materials and similar domestic products.
