Beneath Heat Dry Screed Mix Between Joists UFH System - Underfloor Heating System
Verified by manufacturer 3 months ago
Underfloor heating (UFH) system for use between timber joists, pipes stapled to batten-supported insulation and covered with 25 mm of dry screed mix, to be in contact with the floor deck.
Application
Underfloor heating (UFH) system for use between timber joists, in new builds and renovation.
Description
Underfloor heating (UFH) system for use between timber joists.
Battens are fixed to the side of the joists with a minimum of 50 mm insulation above leaving a gap of 25 mm.
The pipe is stapled to the insulation then covered with 25 mm of dry screed mix, eliminating any air gaps in between the dry screed mix and underneath the structural floor deck.
Features and benefits:
- Cost-effective solution.
- No increase in floor height: in between joists.
- Flexible with uneven joist centres.
- Benefitting from thermal mass, when the pipe heats up the heat spreads across the dry screed mix and retains the heat for longer, giving an even heat distribution.
- Available in 150 and 200 mm pipe centres.
- Compatible with 16 mm-diameter PERT and MLCP pipes.
- Heating performance*:
- 150 mm pipe centres: 63 W/m².
- 200 mm pipe centres: 62 W/m².
*Heat output at a flow water temperature of 45°, based on a tog rating of 1 with a room temperature of 21°. Consult manufacturer's literature for full details.
