BETWEEN JOIST
A proven heating system that sits perfectly within new or existing joists.
When retrofitting an underfloor heating system to a suspended timber floor it makes sense to install the heating panels between the joists to minimise the disruption to the existing floor levels. Using a between joist underfloor heating system by JUPITER, incorporating rigid aluminium heat diffusion plates (not a thin and ineffective foil), ensures that sufficient heat output is produced.
Our between joist installations for suspended timber floors also provide excellent sound-deadening properties making the installation of hard floor coverings over party floors a possibility. We achieve this through the use of high density materials and providing multiple different densities through the construction for impact sound transmission to refract across.
Using our panels with 125mm pipe centres it is normally feasible to install 3 pipes between typical 400mm centre joists. The panels are trimmed to the correct width on site by our installation staff.
BRIEF INSTALLATION GUIDE
For a between joist installation the floor joists should be prepared to accept the IDEAL panels. We recommend that 18mm ply is installed, on battens, between the joists. This is to enable the installer to safely install the heating panels and to ensure that the aluminium plates are in physical contact with the floor finish above.
Uneven joists can be levelled with firrings and the ply can then be set to the correct level below the levelled joist.
Floor joists have to be routed to allow underfloor heating pipe work to cross to next bay.
With the IDEAL system, 3 pipes per bay are possible providing a superior output to other joisted floor solutions.
