Underlay is the foundation to all professional floor installations therefore it is essential that the correct product is specified to suit conditions and customer expectations of performance. We recommend using a good quality underlay for all hard subfloors, whether they are made of cement, wood substrate, ceramic or synthetic. Underlay plays a crucial role in ensuring the longevity and performance of flooring. Acting as a buffer between the subfloor and the flooring, it provides essential support and protection against moisture, temperature fluctuations, and sound transmission.
