H 3.6



Underlay with moisture barrier for Floating Floors.

PolyFoam is recommended for use with all Junckers Solid Hardwood - as well as engineered Floors, where a moisture barrier membrane is required.

PolyFoam is a resilient, step sound absorbing 2 in 1 underlay mat for floating floors. It consists of a polythene membrane laminated to an extruded foam mat in such a way as to allow a 100 mm overlap of polythene on one side with a built-in tape.

PolyFoam is non-absorbent and must be laid foam-side down to prevent perforation of the membrane by sand or gravel particles.
