XPS Laminate Flooring Underlay
Product Description
The Insupad floor underlay is an underlayment for laminate flooring made from extruded polystyrene (XPS). This product is capable of leveling uneven subfloors, has high resistance to heavy loads, and reduces the noice generated when walking. The sheet layout makes cutting and quick installation easy. Insupad is suitable for all types of floating floors. For additional moisture protection, the use of a moisture barrier layer is recommended.
