insulbar® RE – The sustainable insulating bar made of recycled polyamide

Group of people holding out green thumbs to the observer
Ecological "green" construction is all the rage, and building certification in line with green building labels such as LEED or DGNB are gaining in significance all the time. With insulbar® RE, Ensinger is providing a thermal insulating profile belonging to the high sustainability profile category which helps architects and planners in their bid to comply with required environmental standards – without compromising on their accustomed standard of proven Ensinger quality.

Insulating bars for minimal environmental impact and optimum sustainability

insulbar® RE is made of 100 % recycled polyamide, and so saves precious energy and precious resources right from the manufacturing stage. Compared to conventional polyamide bars, the consumption of fossil fuels is reduced by 92 %, carbon emissions are cut by 91 % and water consumption by 78 % – as conformed by the EPD (Environmental Product Declaration). When assembled, the profile provides impressive thermal separation, enables excellent Uf values and so reduces energy consumption and heating costs.

The guarantee of reliable function in the long term and satisfied customers

insulbar® RE provides outstanding mechanical properties and is also identical in terms of its durability and functional reliable to conventional insulbar® insulating profiles. Because instead of polymer blends or mixed recyclates we use only unmixed polyamide recyclate. This is upcycled in such a way that its properties are comparable to those of new material. In this way, continuous quality surveillance and suitability testing of the plastic in compliance with DIN EN 14024 guarantee optimum quality. The profile is available in standard designs or produced to individual customer order.
