Penoroll FEATURES

Ventilation

Special structure consisting of EPS granules and special foils generates ventilation so that the moisture can evaporate. 

100% synthetic materials
Synthetic materials are more stable and less likely to deteriorate than natural fibres. These stabilized materials require no chemical additives. The fewer chemicals introduced to your home environment the better.

Sound features
Penoroll underlay meets the latest requirements for impact sound isolation. it also prvides a deep and rich solid sound in the room.

Ideal with floor heating

Penoroll has a low thermal resistance which makes it ideal to use with a floor heating system. 
Thermal conductivity 0,082 W/m•K

Compressibility
Penoroll holds in its shape well under the load corresponding 700kg/m2. During the seven day test period Penoroll lost only 4% of its thickness. Commonly used foams lost 56% of their thickness in the same test.

Levels the sub-floor
Only Penoroll underlay has a consistency that forms itself to the sub-floor. It eliminates slight variations and provides even and firm support to the flooring. Variations in a sub-floor surface can cause movement where the boards of floating flooring are joined together. Movement weakens the joints which may led to squeaking floors and possible separation of the board.
