The Dual Overlay Heatpak is a free-floating system designed for use over the foil heating mats. It provides a smooth and seamless subfloor making it suitable for soft and resilient floor coverings such as carpet, vinyl and linoleum.
Installation is quick, clean and dry making it an easier option for installers as there is no need for self-levelling. The low heat resistance allows heat to pass through the floor finish without any reduction to the efficiency, evenly distributing the heat and alleviating any hot spots.
The Dual Overlay Heatpak consists of a base board and a top board. Both boards are provided with a contact adhesive, bonding them together to make one solid subfloor, to which a variety of floor coverings may be fixed.
Please Note: when the overlay system is used with carpet the combined TOG rating of both underlay and carpet cannot exceed 2.5 TOG.
The Dual Overlay is a floating sub-floor. It is not fixed to the floor below. Each layer is laid out with staggered joints and arranged so that the top boards overlap the joints in the baseboards. Baseboards are thinner and have a protective plastic film to keep the self-adhesive coating clean. This is laid facing upwards and the film is left in place until cutting and fitting is completed. The top boards are thicker and have no plastic film over the adhesive coating.
Now you have installed the Dual Overlay boards you can either glue your final floor finish to the boards as a final layer or simply lay it freely upon them. Before installing the final floor finish test the foil heater(s) and floor sensor to ensure that no damage has occurred during the installation.
This method of installation will provide a stable surface for the floor finish to rest on and avoid any joints showing through the final floor finish.
