Protect a new floor from moisture penetration and ensure it is comfortable underfoot by fitting appropriate underlay and damp proofing beneath it. Place these items underneath the floor to give it the support and strength it needs to provide households with a quality, long-term investment. In most cases, underlay and damp proofing is a thin layer of cushioning made from materials such as foam, polystyrene and polyethylene to provide a softer feel when walking on it and insulation against noise, heat and moisture. It also reduces natural wear and tear over time, prolonging the life of a design. There is also a liquid version available that can be simply applied by a roller, brush or squeegee and is solvent free. As well as keeping a floor nice and dry, underlay and damp proofing helps retain heat to save money on household energy bills.
