We offer you a choice of four window models where you can combine the frame and sash to create 16 different exteriors, and three interiors. All to ensure that you find the right style for your property. All products are custom made to your specifications, down to the last millimeter. This allows the fitting to be both faster and also much more convenient. The most exposed parts of the window, the frame and outer sash, are made out of strong aluminium fitted with weep holes. This prevents the window from rotting, and provides you with a product with a superior life span. The interior is made from timber with a high quality decorative finish.
