Euro Inward Opening System

The Euro Inward System is a solid metal casement inspired by the continental preference for inward opening windows, allowing for the use of exterior shutters and improved access for cleaning and maintenance. The frame incorporates double weather seals and integral drainage and is designed to take 24mm Argon filled double glazed units. In most cases windows can be installed and glazed from inside the property. A range of decorative ironmongery compliments the handcrafted, bespoke nature of the product.
