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. 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 insulbar^®LI 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.
