Aluminium windows offer strength, durability and are highly resistant to rust and corrosion. They provide slim-lines, more glass area and less visible frames.

     Our standard aluminium systems encompass multiple and varied configurations: fixed, sashed, casement, bays and gables. Fully weather stripped to achieve the highest levels of weather performance. All profiles incorporate polyamide thermal barriers to meet the latest Building Regulation requirements in terms of U values and window energy ratings.
