Profi-joist uses galvanized pipe clips attached to joist edges. With a fast response time and no need for equal joist spacing's, Profi-joist is ideal for any joisted floor.

The Profi-joist system combines 450mm long galvanised pipe holding clips, which are attached to joist edges. Random joist spacing's are easily accommodated with this system, making it ideal for adding underfloor heating into older buildings.

Once installed, either a chipboard floor deck, or solid timer flooring is installed directly to the joists.


Installation:

Insulation is fitted between joists, leaving a 16mm space down from the joist top. Pipe clips are fitted along the joist, which hold the 16mm Pex-Al-pex pipe.

After pipe installation, the remaining 16mm deep gap between pipes is filled with Rockwool or similar. The floor is then covered with 0.5mm aluminium sheets, prior to either a structural timber finish floor, or chipboard.
