insulbar® LI – the efficient insulating profile for the middle insulating segment

insulbar® LI is a new thermal insulating bar in the high-efficiency profile category which intelligently combines energy efficiency and cost-effectiveness. It is positioned between the established standard profile insulbar® REG and the lambda-optimised insulbar® LO. With insulbar® LI, it is possible to reduce Uf values cost-effectively even in the middle insulating segment and improve the insulation effect of the relevant window systems.

The insulating profile from thermally improved material

The reduced thermal conduction capacity of insulbar® LI is achieved by means of a special manufacturing process in which glass fibre-reinforced polyamide is foamed. Compared with standard profiles made from solid polyamide, the lambda value of insulbar® LI can – in optimum products – be reduced from 0.3 W/mK to 0.21 W/mK*. This value makes it possible to achieve smaller installation depths while maintaining the same Uf value, or to optimise the Uf while keeping the installation depth the same.

Optimise and vary window systems with ease

Existing window systems can easily be thermally improved through a switch to insulbar® LI and/or be offered in additional variants with different Uf values – without further system or process changes and without any difference in visual appearance or quality. Depending on the original system, a switch to insulbar® LI makes it possible to reduce the Uf values by around 0.1 W/m2K.
