HiDeck Overlay18 is ideal for acoustic application incorporating underfloor heating. Constructed using tongue-and-groove high-density gypsum, it helps to protect the floor heating system and provides a stable surface for the final floor finish. HiDeck Overlay 18 is recommended for use with several of Warmup’s hydronic systems including the VLo Ultra-12 Low Build System, the VLo Econna-12 Joisted Floor System and the Contura Floating Floor System. It can also be used with the electric Foil Heater. At only 18mm deep, it will have a negligible impact on floor heights. The HiDeck Overlay 18 boards can be used in place of traditional liquid screed or levelling compounds for a faster install. Its high thermal conductivity provides rapid system reaction times, enhancing the energy-efficiency of floor heating and in turn, helping to reduce running costs. HiDeck Overlay 18 is suitable for installation with all subfloor types and directly accepts a wide variety of floor coverings, including tiles, allowing a smooth install.
