Linitherm PAL HW - For tiled and metal roofingLinitherm PAL HW boards are produced by Linzmeier in Germany specifically for use under metal roofing and roofing tiles. PAL HW has 2 integrated vapour barriers comprising of 100% aluminium foil on both the cold and the warm side. The PUR/PIR rigid foam is factory bonded to a 22mm external grade particle board. The board and the PIR/PUR is factory routed with tongue and groove perimeters interlocking at the edges reducing potential for cold bridging. Available in five thicknesses to achieve recommended ‘U’ values. Additional non timber topped Linitherm boards can be placed beneath if required to achieve better values, but must be above any additional vapour barrier such as Alutrix 600 or equivalent laid directly over the deck. The deck can be 18mm plywood with fixings into rafters, or trapezoidal steel using appropriate fixings.

Linitherm PGV FLEX is specifically designed for standing seam curved and barrel vault roofing. The material is notched top and bottom allowing the rigid PIR/PUR to take curves without the need to cut and facet on site. This prevents gaps between facet board joints, reduces on site labour costs, saves on site waste and speeds up install. The build up from deck to metal would be minimum 18mm exterior grade plywood deck (can also be 3x6mm or 2x9mm depending on radius), alutrix 600 or equivalent vapour barrier, double layer Linitherm PGV FLEX,Tyvek Supro or equivalent breather membrane, system through fixed to deck with Thermoseam TS25, Krabban or equal thermally broken standing seam fixings, choice of standing seam material directly laid over.
