FIRMFIT® Premium Planks is an innovative waterproof SPC floating floor. The dense and rigid core will not telegraph subfloor irregularities, is more temperature stable and more impact resistant than floating LVT and WPC. Firmfit Premium can be installed in large areas (up to 4000 sft) without transitions. The vinyl surface layer is coated with a high quality urethane finish. The visuals are high quality, realistic with natural embossing and a full wide bevel. Drop-lock installation system for easy installation. FirmFit Premium Plank has an attached cork underlayment providing added sound insulation and can be installed over most existing subfloors.
