Internorm has significantly improved thermal insulation in PVC frame profiles by inserting expanded polystyrene (EPS) beads that are HCFC-, HFC- and FC-free. The pearls are blown into the frame with a specially designed filling station that allows continuous and complete filling – also in the corner section of the window profile. The Uf (frame) value of uPVC windows decreases from 1.1 to 0,92 W/mÇK, an improvement of frame insulation of 20%. Material costs for insulation measures are significantly reduced, a further step towards affordable climate protection.
