Sheerframe 8000 Top Reversible windows from Synseal fully reverse for ease of cleaning in total safety from inside the building.

This specialist Top Reversible window design features a purpose-designed Sheerturn hinge and is ideal for domestic applications including escape windows as well as medium and high rise dwellings and office or hotel accommodation.

A range of transoms and mullions provide additional multi-light and stick construction curtain walling configurations to complement this user-friendly window design and deliver effective fenestration solutions for commercial buildings.

Sheerframe 8000 Top Reversible windows are part of an enhanced thermal performance range which offers specifiers, fabricators and professional installers the widest range of fixed and opening light combinations. The 70mm window profiles are extruded from calcium organic lead-free Sheerblend impact modified PVC-U complying with BS EN 12608 and feature thermally-efficient Thermlock frame reinforcements, five separate insulating chambers and twin co-extruded weather seals to maximize weather performance.

Top Reversible windows can achieve U values as low 1.2W/m2K using standard 28mm double glass with Argon gas fill. To exceed Part L of the Building Regulations, triple glazed low energy Zero Carbon windows with U values down to 0.8W/m2K are also available, using either 36mm triple glass with Krypton gas fill or 44mm triple glass with Argon gas fill.

The Sheerframe 8000 Top Reversible is fitted with the reversing Sheerturn hinge allowing the window to open out traditionally, retaining the advantages of a casement but reversing for safer cleaning from inside the property. The window is balanced at all angles and has a locking restrictor on both the initial opening position and also on the fully reversed position. Windows are manufactured to customer specification and the maximum recommended size for individual opening lights is 1250mm wide by 1500mm high.

Popular colours including Rosewood, Light Oak, Anthracite Grey, Black, Cream and White are held in stock at Sheerframe Ltd, with other colours available on a ‘made to order’ basis.

As an optional specification, this window can also be configured as a Side Reversible. The hardware for a Side Reversible is similar in operation but allows the windows to be opened on a horizontal axis. This gives in excess of 90% open area and therefore can be used to achieve compliance with fire safety regulations.
