Floor Constructions: Timber Joist Floor

Plate System

The Evenheat 'double plate' system fits traditional 400mm (16") joist centres. Two pipes are installed between each joist, boosting response times. The 0.5mm pressed aluminium heat diffuser plates hold two pipe channels shaped to ensure good conductivity to the plate.

Please note that when installing at 200mm centres, the pipe must bend on a 300mm radius (creating a 'light bulb' shape).

The Plate system can be installed by stapling the plates directly to the joists. However, care must be taken to ensure that any notching of the joists is carried out in compliance with building regulations. The alternative Cross Battened method avoids the need to notch the joists, and also avoids fitting problems on non-standard spacings.

Cross-Battening

Minimum batten thickness to suit the plates is 20mm. However, the thickness of batten must satisfy the structural spanning of the floor decking or covering. As with all floor heating systems, insulation is required to prevent downward transmission of heat.
