A1 windows have been designed to reduce heat loss by the use of a thermally broken aluminium frame with a polyamide bridge. The polyamide material has a very high resistance to heat transfer from the inner face of a frame (i.e. inside a room) to the external face of a frame (i.e. outside). The thermally broken frames provide homeowners with windows and doors that have distinct advantages.

Strength & Durability are provided by the use of Aluminium sections which gives structurally sound windows and doors for your peace of mind.

Warmth & Comfort are benefits enjoyed by homeowners because A1 windows are thermally efficient and contribute to a reduction in the cost of heating bills.

Elegant Slim Sightlines are features of the A1 windows which are enhanced by an ovolo, chamfered or square profile edge appearance. Additionally, homeowners have a dual colour option which means having a choice of finishes and colours externally and internally.

The A1 range of windows offers all you would expect from a quality system – Greater comfort, better insulation, minimal maintenance, aesthetically pleasing appearance and enhanced security. In short, the A1 product range offers you peace of mind but even more it represents a sound investment in your property.

Whatever your taste or style of home, we can offer distinctive window designs to suit. Our unique style of windows are available in a choice of finishes and colours externally including luxurious mahogany and rich golden oak as well as a white finish internally.
