The Belvedere window is as beautiful on the outside as it is on the inside. From the Latin meaning 'beautiful view', the new Belvedere window system is as beautiful to look at as it is to use. But the real beauty of Belvedere is not confined to just one side - using the latest techniques in window system design and development. Belvedere can boast stunning curves to it's profile on both the inside and outside aspects of the frame. The Belvedere is further enhanced by low glazing sight lines to produce a clean crisp appearance. So no matter what your point of view, you can be assured of a pleasant one. All windows are supplied with Neutral Plus 1.1 Argon filled gas units - [see details here] Self locating hinge Locks The stainless steel friction hinge is tested to 20,000 cycles and incorporates a captive head providing additional security, smooth engagement and weather sealing. Roller cams Stainless steel mushroom head rollers operated by the New Belvedere gearbox, provide unrivalled security and reliability. Upon closing the window, these roller cams (A) slide easily and securely into the roller cam keeps (B) in either the fully closed or vented position allowing air to circulate. Shootbolts Heavy gauge, stainless steel shootbolts provide corrosion resistance and high security to New Belvedere windows. All have been tested and have successfully achieved the prestigious BS 7950 criteria for advanced window security. The shootbolts locate securely into their equally strong keeps at the top and bottom of the frame. Reverse wedges Added compression and weather rating is sometimes required. All opening casements over 1000mm will have reverse wedges fitted as standard half-way down the hinge ensuring complete weather sals every time the window is closed
