It is dense (850kg\/m³), so it cuts impact sound by up to 25dB and stops a laminate or engineered floor sounding hollow when you walk on it. That makes it a good pick for upstairs rooms and flats.\u003c\/p\u003e\n\u003cp\u003eThe rubber is a closed cell type with a silver foil layer bonded to it, which acts as a built-in vapour barrier. You don't need a separate damp proof membrane on top of a concrete subfloor, and the rubber helps even out small dips in the floor.\u003c\/p\u003e\n\u003ch3\u003eWhat it's for\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFloating \u003ca href=\"\/collections\/laminate\"\u003elaminate\u003c\/a\u003e and \u003ca href=\"\/collections\/engineered-wood\"\u003eengineered wood\u003c\/a\u003e floors, including click systems\u003c\/li\u003e\n\u003cli\u003eRooms where noise matters, such as bedrooms over living spaces, and flats\u003c\/li\u003e\n\u003cli\u003eConcrete or timber subfloors\u003c\/li\u003e\n\u003cli\u003eLow-temperature underfloor heating (flow temperatures below 45°C).
