These windows were developed in the late 1960`s and have outward opening sashes which have an overlapping 'lip' onto the frame creating a picture frame effect. The idea is that this additional lip gives additional protection to the window frame, especially when a second weather seal is fitted into the lip in addition to the seal on the inside of the frame between the frame and the sash.

As with all outward-opening windows (and doors), the harder the wind blows the more the sash presses against the seals, compressing them to fill any gap between the sash and the frame.

Outstanding security performance is achieved through hidden hinges and multi-point locking. Floating mullions (or French mullions) allow adjacent sashes to open and give an unobstructed view.

This window is independently tested to exceed the British Standard for security BS7950 and carries the Secured-By-Design seal of approval from the Association of Chief Police Officers.

These windows are double glazed, as standard, with low-emissivity glass, it offers excellent thermal insulation and carries a Window Energy Rating (WER) A. They are also available with single and narrow, heritage style, double glazing for those locations where it may be required.
