Aluminium Windows

Aluminium windows are enjoying increased popularity thanks to modern manufacturing techniques and engineering design. They are usually the window of choice for architects and construction companies as they offer elegant design, durability and fantastic thermal efficiency.

SDB ALUMINIUM windows are British designed and manufactured to the highest standards and specifications. They are precision engineered to enhance the appearance and thermal efficiency of your home. Each installation will be individually surveyed, measured, quality inspected and then installed by our own specially trained and monitored teams.

Style Choices

One of the main reasons why people choose aluminium windows over uPVC, or even hardwood, is the comparatively slim profile of the frames. Naturally this offers a greater glass area to improve visibility and light ingress but with no loss of aesthetics, security or thermal efficiency.


Security is a most important consideration when replacing windows in your home. All of our windows meet or exceed Police and BSI Kite Mark recommendations. Each has multipoint shoot bolts which lock into the frames as well as key lockable handles. All are fitted as standard with espagnolette locking mechanisms which allow the window to be locked part open for ventilation with security. All upstairs windows will be fitted with Fire Egress hinges, to comply with current building regulations, and may also be supplied with restrictor hinges or easy-access hinges for ease of window cleaning from the inside. All are internally beaded to prevent the glass from being removed from the outside.

Weather Resistance

Our aluminium windows are designed and manufactured with the British climate in mind. The windows and frames have multi-layered, durable weatherproof seals and yet are virtually maintenance free.

Energy Performance

All of our aluminium bi-fold doors exceed current building regulation requirements. All are manufactured with thermal barriers between components, multiple weatherproof polyethylene seals and high performance glass sealed units which effectivelyretain the heat in your house.

Other glazing options include Pilkington self-cleaning Activ glass, solar reflective for South facing windows and even triple glazing for enhanced sound and heat insulation. Discuss these options with your friendly surveyor.

Frame Finish

Our windows are available in four standard finishes at no extra cost. GLOSS WHITE RAL 9016, MATT WHITE RAL 9010, MATT GREY 7015M and BLACK RAL 9005.

Alternatively you may choose a bespoke colour from over 200 in the RAL colour chart.
