This low-profile underfloor heating system is installed directly over an existing structural floor (solid or timber floor deck) for minimal disruption to your new build or renovation project.
The new patented Overlay® Plus boards have a dense insulation core and an aluminium lining which increases the product’s heat output by 15% compared to traditional Overlay®. Pipe is simply laid in grooves within the boards’ surface. The boards have a fleece finish so tiles can be applied directly without the need for an intermediate surface – further reducing build-up of the floor height. Laying underfloor heating panels formed of extruded polystyrene giving them their lightweight feature while also providing additional properties such as.
• Thermal insulation
• Easy decoupling
• Waterproofing
The panel features two thin layers of fibre-reinforced polymer concrete with a polyester fleece coated layer on top of a reflective aluminium foil. The aluminium layer is designed to evenly diffuse the heat from the pipes over the surface of the board. A version to reduce the transmission of impact noise is available with a layer of synthetic rubber on the bottom side. As well as increased system performance, the boards offer a host of installation benefits too. They are large but lightweight so can cover large floor spaces very quickly.
Features & benefits of using the Overlay ® Plus system
• Best practice over the floor system
• Thermal insulation properties with improved heat output and reduced downward heat loss
• Low profile system – only 18mm high
• Larger lightweight pre-grooved aluminium foiled panel
• Easy to cut and shape so fits any size and shape room
• Suitable for multiple floor coverings and larger projects
• Can be tiled directly on to
• Sound reducing characteristics (Overlay® Plus Acoustic Panel)
• Use with 12mm UFH Barrier Pipes (Made in Doncaster).
The Overlay® Lite 15 underfloor heating boards are installed directly over an existing structural floor (solid or timber floor deck) for minimal disruption to your build or renovation project. The profile of these boards is slightly higher than our other Overlay® systems, sitting at 22mm rather than 18mm. Laying underfloor heating 15mm diameter pipe rather than 12mm. The larger pipe diameter means larger spaces can be covered quickly and with fewer circuits, making this system particularly well suited to larger projects. The advantage of having fewer circuits is that a single manifold can service a much larger space. As with our other Overlay® systems, the pre-grooved boards hold the pipe in place. No additional insulation is required, and this system is suitable for most finished floor coverings.
The panels are quick and simple to install (lightweight, easy to cut to size and lay), and also offer the best system performance in terms of heat output. The unique castellations act as a guide for laying underfloor heating pipe at the required intervals and facilitate the best practice spiral configuration. The panels also raise the pipe up and off the insulation panels, enabling the underfloor heating pipes to be fully enveloped by the screed. This 360-degree contact with the pipe means the floor slab absorbs and retains the heat better, giving the room optimum heat output (approximately 15% less screed required).
The Staple System is a cost-effective way of installing underfloor heating in new solid/screeded floors. This system uses plastic staples to fix the pipe directly to the insulation, after which a screed or concrete floor is poured on top. It relies upon freehand pipe placement or use of a staple gun for laying underfloor heating by the installer. Liquid floor screed is a good long term investment, especially if you have an underfloor heating system. It encases the pipes entirely, eliminating air bubbles and maximising thermal conductivity, i.e. the speed at which the floor warms up after turning on the heating. Traditional sand/cement screeds work fine over UFH but the heat transfer will be slower as the product is less dense.
The Low-Profile Screed underfloor heating system allows for a lower finished floor height to be achieved as it can be utilised with screed depths from as little as 35mm Self-adhesive backed interlocking pipe retention panels enable rapid installation, each 600mm x 600mm x 20mm panel features multiple pipe retention clips which hold the pipe securely in place, together with purpose made locking features which fasten the panels together. Helping with laying underfloor heating.
With suspended timber and composite joists the pipe is supported by spreader plates that distribute heat evenly across the timber floor covering. underfloor heating spreader plates come as single or double panels, allowing the double spreader plates to be secured to the joists from above, prior to laying underfloor heating pipe then the floor. Single spreader plates can be stapled from below if the floor is already fixed down but this process is slower and more difficult than laying the pipe prior to fitting the floor.
