Here at Hepworth Framework Ltd we use a range of the SPW300, SPW600 and AliVU windows from Senior Architectural Systems. The window options include casement, tilt and turn, overswing and pivot. The AliVu windows have slim profiles, light weight and are designed to best fit the residential market. The SPW300 and SPW600 ranges are more suited to the commercial market, however this does not mean they cannot be used for residential projects. If you are looking for something other than your typical aluminium windows we have the Hybrid range of windows. These are constructed with durable, low maintenance aluminium on the outside with the warmth of engineered timber on the inside, giving you the benefits of both materials.
