A next-generation, self-supporting, room-in-a-roof system for pitched roofs has been launched by leading PIR manufacturer Recticel Insulation.
The innovative new product, L-Ments, comprises cable gap, breather membrane, counter battens and integral structural timber in one PIR insulation panel as a single lightweight cost-effective modular roofing element, making it exceptionally quick and easy to install.
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.
The future-proof system has been designed for ultimate thermal performance, 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.
Using L-Ments in conjunction with Recticel’s full-fill cavity wall insulation Eurowall + and high performance floor insulation Eurothane GP provides specifiers and contractors with a holistic building solution for the complete building envelope that showcases a fabric first approach to construction as well as Modern Methods of Construction via the use of fewer materials and speedier installation.
Available in four different thicknesses and five different lengths, the panels feature shiplap joints.
