About this product

Aluminium Heat Spreader Plates are designed for use with wet underfloor heating systems.

Aluminium spreader plate dimension are 1000 x 390 mm to suit underfloor heating pipes sizes from 15mm -16mm in diameter, each aluminium underfloor heating spreader plate has twin / double preformed groves for pipes at 200 mm centres. Comes in a pack of 100

These underfloor heating spreader plates have an omega shape grove to clip and hold the pipe securely unlike a straight U channel spreader plates.

Each water underfloor shop aluminium double spreader plate will cover a heated floor area of 1/2 m² allowing sufficient spacing between each spreader plate, and also at the edge of the room where the pipe turns 180° back into the spreader plate.

The underfloor heating double spreader plates are suitable for suspended floor systems and are fitted on top of floor joists or battens at the standard 400 mm centres (should the joist spaces vary this can be usually overcome on site).
Underfloor heating spreader plates have preformed channels with pipe centres of 200 mm, spreader palte can be nailed, screwed or stapled onto the top of the floor joist or floor batten.

The aluminium underfloor heating spreader plates will give the underfloor heat output of 77 watts per m² at room temperature 20C with a floor temperature of 27C. Any variation on either of the these two temperatures this will vary the heat output ( or -) from the underfloor heating system.

We recommend that the spreader plate sits snugly beneath the floorboards giving direct contact to the floor board, which will then give the maximum heat transfer from your water underfloor heating system. Insulation should be fitted directly beneath the ufh spreader plate.
