F10 - BETWEEN JOIST INSULATION PANELS This system utilises a combination of our 50mm, 200 kPa insulation with main panels laminated with thick 200 microns of aluminium for rapid response, and plain end return panels. This panel is suitable for New Build, Renovations or Extensions and eliminates the need to purchase extra insulation and spreader plates. Simple to fit using panel support brackets (purchased separately) and easy to cut using a fine toothed saw. END RETURNS ARE AVAILABLE SEPARATELY. ONLY COMPATIBLE WITH PIPE SPACING SET AT 200mm. Main panels are laminated with thick 200 microns of aluminium and pipes set at 200mm spacing, End returns are left bare and purchased as a separate panel which incorporates the end return and transitional runs. They are lightweight, easy to lay and can be installed quickly.

In order to install between joist panels between existing joists, original floorboards will need to be removed, after fitting between joist panels, boards can be reused or replaced. Once joists have been exposed and inspected, use our panel support brackets to install panels flush with joist top. Alternatively wooden battens are fixed to both sides of each joist in order to take an 18mm ply board. The 18mm ply should be set 51mm from the top of the joists. This board serves two purposes; to hold the 50mm profile heating panel in place and to act as a supporting floor for the installer. The ply and battens can be set lower on ground floor installations to accommodate further insulation. The high density 200 kPa polystyrene panels are easily trimmed where required and then placed within the 400mm spaced joists so that the aluminium spreader plates are level with the top of the joists. Floor heating pipe is then inserted into the omega shaped channels in the aluminium spreader plate. If permissible notching the end of each joist will allow the floor heating pipe to pass between joists. If notching is not allowed then an 18mm batten can be attached to the top of the joist which is run short at one end to allow pipe to pass between joists. Joist panel supporting battens will need to be raised accordingly.
