Car Builders Water Proof Carpet Underlay is a single layer, closed cell foam, meaning it does not hold water. It also works great as a thermal and acoustic insulation barrier.

It is suitable for 4x4's, convertibles and industrial vehicles, which get constantly exposed to wet environments.

Car Builders Water Proof Carpet Underlay will not stay damp, smell, rot or attract mould like pre-dated cotton mill scrap, traditionally used under carpets.
