good quality xps foam underlayment heat insulation panel The Board is made of Extruded Polystyrene.This kind of board is widely used for building insulation. When the house is installed with the boards, it is just like a thermal barrier. The heat lose can be greatly reduced. When used under underfloor heating the board greatly increases the response rate and overall efficiency of all under floor heating systems Characteristic of good quality xps foam underlayment heat insulation panel Stable performance and anti-aging: The extruded polystyrene (XPS) insulation boards can be used 35-50 years. Resistance to compression: compared with other thermal insulation material(200Kpa for EPS), it has better compressive strength(around 300Kpa), which make it the ideal solution for heavy domestic or industrial loads Water resistance: Polyfoam is almost 100% closed cell and as such is unaffected by moisture Lightweight: volume optimization and easy to handle Resistance to deformation Resistance to impact Versatile: the closed cell structure and density of Polyfoam allow specific edge details and surface finishes to be cut into the boards to make them as fit for the job as possible. Moreover, Polyfoam can be cut into almost any shape. Recyclable: Polyfoam can be 100% recycled Application of good quality xps foam underlayment heat insulation panel The foam board is good to use on roof, wall and floor insulation.
