A pre routed, cement coated XPS panel, for use with water based underfloor heating systems.

Board Specifications

• 1200mm x 600mm (0.72m²)
• 22mm/2.6kg
• 150mm Centres
• For 15mm & 16 mm Pipe
• Thermal Conductivity 0.033W/mK
• Euroclass E
• 300 KPA

The routed overlay panels are manufactured from high density XPS 300kPa which is thermally insulating, lightweight, waterproof and faced with a reinforced cement coating. The panels provide a quick and easy solution for the placement of pipework for domestic and commercial underfloor heating applications. The lightweight, reinforced cement facing, provides a robust surface that is ideal for direct bonding of tiles. Many other types of finishes such as engineered wood, carpet, vinyl etc. can also be used, subject to additional preparation of the panels.

The panels are ideal for fitting onto solid floors i.e. concrete, screed, asphalt floors, and also suspended timber floors that have been boarded with suitable floor boarding such as tongue & groove planking/chipboard planking etc.

Easy to cut and install – The panels should be laid with the panel joints staggered in a brick bond style. The routed channels are compatible with most flexible low-pressure underfloor heating pipes. The panels are designed for use over existing floors providing a low height build up, insulated floor.

Available for use with 15mm & 16mm pipes with centres at 150mm. At the end of each panel is a series of pre formed return loops and 3 x routed channels which allow flexibility and versatility for multiple heated zones to be fitted.

Duo Board is a free floating HDF sub-floor specifically designed for installation over floor heating to provide a smooth, stable and level base for laying off the roll carpet, vinyl and linoleum directly onto.

The DUO BOARD system comprises of two layers, a base board with adhesive surface and a top board both are laid in an overlap/brick bond fashion. (For Karndean and Amtico planks we would recommend a renovation screed as a sub floor and not Duo Boards). Expansion joints required in any 8 mtr direction.

Dimensions: 1200mm x 600mm x 3-4mm

Quantity: 1 = 4 pairs of Duo Boards, 0.72m2 each, 2.88m2 per pack

IMPORTANT: Before installation, the Duo Boards must be stored for a minimum of 48 hours at a temperature not lower than 18°C and a relative humidity of no more than 60% in the room where the Duo Boards are to be used.

PLEASE NOTE: You can not use tile adhesives or levelling compounds on these DUO BOARDS

• DUO BOARD is a quick, simple and dry solution to install with a very low thermal resistance allowing heat to transfer quickly and easily for a rapid response and maximum comfort. Made from HDF high-density fibreboard, which is engineered wood fibres that have been highly compressed. It is similar to MDF, medium-density fibreboard but is denser and much stronger.
• The base board is laid first with adhesive side facing up then the top board is then laid brick bond fashion onto the exposed adhesive surface producing a seamless surface, preventing ‘joint lines’ from showing through carpet, vinyl and linoleum floor finishes.
• When laying DUO BOARD allow an expansion joint every linear 8mtrs, the expansion joint should be between 5mm to 10mm and can be filled level with the board surface using a flexible sealant/filler.
• DUO BOARD is not suitable for use in bathrooms, wet rooms, en-suites or any other wet areas, the boards will expand upon contact with moisture.
• DUO BOARD is not a structural sub-floor for use as replacement of floor boards/decks.
