Recticel Insulation’s L-Ments system comprises cable gap, breather membrane, counter battens and integral structural timber in one polyisocyanurate (PIR) insulation panel as a single lightweight roofing element.
The underlay felt is pre-glued and vapour permeable with self-adhesive overlaps. The counter battens are already fixed to the panel, the multi-layered facings act as a vapour and air barrier on the inside, the PIR insulation core performs thermally to 0.023 W/mK, and the timber stiffeners incorporated within the PIR core provide sufficient strength for self-support, Recticel says
The system has been designed with U-values of between 0.13 and 0.19, as well as fast installation and reduced construction costs, with maximum savings on space and energy usage, the manufacturer claims.
The panels have shiplap joints and are available in four thicknesses and five lengths.
