double glazed Windows
Styles & Colours
Choosing your style of double glazed window can be influenced by several different things, a design to complement your home, ventilation requirements, fire escape requirements or an individual design with some decorative glass to add your own touch of flare.
Double glazed windows have evolved, in the early years of double glazing the main criteria was to replace rotten timber windows with PVCU double glazing which was "maintenance free". Home-owners today want more from double glazed windows, they still want to reduce maintenance on there homes but energy efficient and secure double glazed windows are often the priority. With the Pilkington Energy Care range of glazing we offer a range of double glazed windows that keeps the warmth in your home and save you money.

Deceuninck has long been regarding among the best for quality of finish and durability so you can feel confident that your double glazed windows and doors will stay beautiful for longer, with very little maintenance.
Bay/Bow Windows
Bay / Bow windows are an attractive feature to any property. They also make a big difference to the feel of a room, the room will feel much larger. They are constructed using normal fully reinforced window frames in either the decorative or chamfered system. The frames are connected using structural bay pole assembly kits or reinforced corner posts for square bay / bow windows. The external sill, which the frames sit on, is welded together to create one sill under all the frames.
Flat –to –Bow Windows:
It is possible to create a bay or bow window from an existing flat window. To create a bay window (with brickwork below) building regulations are required and it becomes quite an expensive process. Alternatively a bow window can be created more cost effectively without the need for building regulations. A flat to bow window has the same frame construction as a normal bay or bow window but with a new timber / scalloped lead roof.
Architectural Bow Canopies (GRP Roofs):
An alternative to a timber / lead roof is to use a GRP bow canopy with an intergraded ceiling. This has an attractive external dental moulding and a high gloss finish. These are manufactured in a set range of sizes, which may have some design constraints depending on the size of your existing window. They are available in white, brown and light brown.
Weight loading bay windows:
Under new building regulations load bearing bay and bow windows are now covered by FENSA. All bay and bow windows are constructed using structural bay pole assembly kits, however under new building regulations load bearing bay pole jacks must now be fitted through the external sill into the bay pole assembly kit. This creates a structural support from the brickwork under the bay or bow window to the head of the aperture.
Replacing Sash Windows
All windows must now be installed to meet with building regulations. Here are the following building regulations which replacement sash windows much conform to.
- Documents “F” (Ventilation)
- Documents “B” (Fire Escape)
- Documents “N” (Safety)
- Documents “F” (Ventilation)
To comply with document “F” all sash windows must be fitted with a lockable night vent facility which is standard on all our casement opening vents.
- Documents “N” (Safety)
Most sash windows will require toughened safety glass, as the glazing will be lower than 800mm from the finished floor leve.
- Documents “B” (Fire Escape)
- Revert to the original design
- Lower the height of the transom to below 1100mm and the top opening vent becomes a fire escape
- Install a fix over an opening vent with a trickle vent for high level background ventilation
- Re-design the window to have two top hung opening vents
