High Density Foam Rollers for superior mechanical performance and durability. Application on floating floors that allows greater mechanical resistance and thermal and acoustic insulation. It can also be applied as a waterproofing and thermal and acoustic insulator placed on the building board and under the screed (or other type of floor), thicknesses from 5mm to 10mm are recommended. Increased durability and a wide range of applications. The Pactpol Force blanket is a sheet of extruded polyethylene foam with a density of 40kg / m3 and a gray color. Possibility of coating with aluminum foil that allows the reduction of electrostatic charges and increases electrical conductivity. Excellent reduction in impact noise of 19 to 24 dB.
