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.
