Warmboard-S is a structural panel. In new homes it’s laid over joists at 406.6 mm centres in place of the flooring sheet, and it can also go over a concrete slab or an existing floor. Warmboard-R is a thinner panel laid over an existing floor on 1.7 mm radiant reflective foil, which suits renovations.
For every project, Warmboard’s design team draws the panel layout, the pipe loop plan and the manifold locations. The pipe is laid at 300 mm spacing.
