Soundlay Foam is a cross-linked, closed cell polyolefin foam which is ideal as a low cost, resilient under-screed layer designed to reduce the transmission of impact sound through concrete floors.

The foam contains EVA rubber cells to give improved acoustic performanceand increased resistance to compression and creeping.

Soundlay Foam is available in a range of thicknesses giving a choice of impact sound insulation values.
