New insulating bar from foamed recycled polyamide: Ensinger combines superior insulating effect with an outstanding environmental footprint
Nufringen (Germany), 21 January 2021 – With insulbar RE-LI, Ensinger is presenting its greenest insulating bar for thermal breaks in aluminium systems for windows, doors and façades. Thanks to the use of unmixed, recycled polyamide, 92 percent fewer fossil fuels are used during manufacture compared with a conventional bar, the CO2 emissions drop by 91 percent, and water consumption drops by 78 percent*.
“In addition, foaming of the recycled polyamide improves the insulating effect of the glass fibre reinforced material. The lambda value is a mere 0.21 W/(m⋅K)**”, says Matthias Rink, Sales Director for insulbar at Ensinger. “So thanks to the low thermal conduction capacity, insulbar RE-LI also reduces energy consumption and CO2 emissions during its entire service life.”
Greener made easy
Manufacturers can thereby enhance the ecological and climate-friendly properties of their aluminium systems by switching to insulbar RE-LI. The recycled polyamide, which is foamed uniformly during its extrusion, has high stability thanks to glass fibre reinforcement. The unbroken, smooth outer shell permits perfect anodizing and powder coating. Processing is similar to that for insulating profiles made from solid polyamide 66.
For several decades now, the material polyamide has proven itself in sustainable thermal breaks in the metal frames of windows, doors and façades. insulbar RE-LI combines double the climate benefits with high cost-effectiveness. The Environmental Product Declaration (EPD) and the Cradle-to-Cradle Material Health Certificate facilitate building certification e.g. in accordance with BREEAM, LEED or DGNB.
