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 U_f 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 U_f value, or to optimise the U_f 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 insulbarLI and/or be offered in additional variants with different U_f 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 U_f values by around 0.1 W/m²K.
