multifunctional underlay with ventilation feature for floating floors

The recent „vertical movement” test confirmed the high compression strength of ProVent. The test was completed with a foot-size 100kg dynamic load which created approximately 3.6t/m2 pressure on the sample flooring.  It was established that the vertical movement range of both laminate and parquet (when installed over ProVent) was less than 0.5mm. This movement causes absolutely no harm to the flooring. On the other hand it is enough to make the air move in the air channels of ProVent, removing in this way the humidity from the underfloor.
