envirowindow® 70mm Casement Windows

Casement windows still remain the most popular window style with the British public and we have over 70 options available. Casement windows are the ideal choice for the direct replacement of existing windows as they can be hinged at the sides or top. Hinged window styles such as casements generally have a lower air leakage rate than other windows because the sash closes by pressing tightly against the frame. All Speed Frame Casement window styles project outwards, this provides significantly better ventilation than other windows of equal size. Click Here to order a brochure

envirowindow® 70mm Tilt & Turn Windows

The very distinctive style and flair of a continental window, offering a chic appearance & combining ventilation with excellent security. The actual operation of this window provides a tilt position for ventilation with the effective ventilation of a side hung window. Additionally, the full width inward opening sash gives a safe cleaning facility allowing both sides of the glass to be cleaned from inside your property and a clear opening when fire escape is required. Mishandling devices stop the window being incorrectly operated and all round locking points ensure weather beating performance in the closed position. Speed Frame's exceptional production techniques allow for a superior and more attractive finished window.
