Western Windows offers a 60mm or 70mm system. This outward opening casement window is available in two styles - standard or bevelled rebates. Each can be either externally or internally glazed with additional patented security features for externally glazed options.

The gasket and sealing system is hidden from the glazing sightline eliminating the black edge, usually found in PVC systems. Clean, clear sightlines offer a modern and attractive look and feel.
