The Heat-Pak® Dual Overlay System is designed to provide stability and versatility for both electric underwood foil mats and water Loflo Lite panels. It offers an optimal subfloor solution, creating a stable base for various floor coverings like carpet, linoleum, vinyl, and cork. The twin layers with an overlap joint configuration ensure a seamless surface, eliminating visible lines, especially under glossy finishes. Installation is quick and easy, being a dry process that requires no setting time, allowing for immediate flooring installation. It simplifies the installation of electric heating systems, keeping elements secure and flat, and offers efficient heat transfer with a low thermal resistance (Rm value of 0.047) for fast warm-up times. The system also allows for insulation beneath electric systems for maximum energy efficiency. Constructed from high-quality MDF (3mm baseboards, 4mm topboards) with a special interactive contact adhesive for a strong bond. It is not suitable for wet areas; use an underfloor heating mat with self-levelling compound for wet areas.
