More Product Information

Hottrok is composed of a unique mixture of Expanded Polypropylene (EPP) foam and special additives that is custom molded into our patent pending design. This material is a superior product for many reasons: it has excellent chemical resistance to alkalines and acids and is highly resistant to humidity and water exposure. It's characteristics make it a great material for this application. It has great thermal and accoustic insulating qualities and helps eliminate heat loss between the tile and the subfloor.
