Duraflex Flush Casement Windows

Duraflex 70mm flush casement windows is a range of windows which can be tailored to your particular needs. These windows offer quality double glazing which looks superb, is designed to withstand all that our British climate can throw at it, and has the thermal properties to save you money as well.

Beauty in Simplicity

The elegant lines of the Duraflex 70mm flush casement windows have a quality which speaks for itself. The windows lie flush across the whole window frame, giving a uniform simplicity to the exterior of the house. Our Duraflex flush casement windows are available in a number of different styles and finishes as individual as your home. You can be sure to find a combination of colour and finish that suits your individual property whether it be a period house, bungalow or new build. These windows also have equal sightlines, which means that the frames, panes and glazing bars are all on one plane for a unified and symmetrical appearance.

A Modern or Heritage Look

The windows, being flush casements, are in keeping with the clean lines of the traditionally crafted windows of the past. They can be finished in flat colour or woodgrain foil, designed to match the appearance of timber, but with none of the maintenance problems of traditional timber windows.

The Duraflex range offers options for either a modern or heritage appearance. You might want the welded joints, flat colour and sleek look of a modern window; alternatively, you may prefer a window with an authentic heritage appearance. We are able to reproduce mechanical sash joints and Georgian or cottage bars, together with the appropriate window furniture. There is a choice of colours; standard white or brilliant white as well as a range of greys, cream, black or green. The woodgrain comes in two different types of oak, teak or rosewood. Both interior and exterior can be tailored to your preference, and there are even single and dual colour frame options.

Outstanding Weatherproofing Qualities

Duraflex’s weatherproof properties come from its weathertight seals and multi-chamber profiles. The thermal insulation provided also ensures that Duraflex windows are excellent at reducing extraneous noise pollution. In order to provide complete weather sealing the gasket supplied in these windows is a superior Q-Lon gasket. A gasket is the rubber seal between the glazing and the frame which can fail after a period of time and let wind and weather into the frame causing a loss of thermal qualities. One of the main reasons for seals not working is that, over time, the gasket has compressed and not sprung back. The Q-Lon gasket has an outstanding compression recovery of 99%. This means that the gasket will stay operative for longer and that even the corners remain at a constant height to repel the weather. The Q-Lon gasket comes with a manufacturers’ lifetime guarantee.

Security

Security benefits from the latest Part Q security as standard with multi-point shotbolts. To be Part Q compliant means that the window satisfies the latest standards of robustness and security performance. There is also an option for upgrade to Secured by Design level which is a police approved initiative designed to ensure a high level of security and tested to PAS 24.
