Increase Your Energy Rating, With Our Deluxe Premium Plus Aluminium Windows

Our new, ultra-energy efficient, premium plus casement aluminium windows add timeless elegance to your home. Complementing our wide range of aluminium windows and doors, these windows have an extremely low U-value, making them the perfect choice.

Capable of being manufactured for both large span atrium, and apex windows, this system can also be utilised in the same way as the more conventional casements. The modern design features flush casements, and slim aluminium square profiles – stylish, yet strong and lightweight. They can be available in any RAL colour, in a range of metallic and textured finishes.

When tested for weather tightness, these casements remained watertight under air pressure 4x the industry standard.

For peace of mind, all of our windows can be PAS 24 security certified. They are also fully compliant with ‘Part L’ building regulations and can be specified to meet ‘Part Q.’
