Product overview
Weather-resistant ventilation with top-hung aluminium profiles
Aluminium awning windows are hinged at the top and open outward from the bottom, creating a natural weather shield that allows ventilation even during rain. The 70mm thermally broken profile system delivers slim sightlines and excellent thermal performance — ideal for bathrooms, utility rooms and commercial applications.
The polyamide thermal break reduces cold bridging and condensation risk. Argon-filled double or triple glazed units achieve U-values as low as 0.7 W/m²K. Available as standalone awning lights or combined with fixed lights and other opening types in multi-light frames.
All frames are finished in T5 powder coat in any RAL colour. Friction stays control the opening angle. CE marked to EN 14351-1. Supplied bespoke to your exact dimensions with an 8–10 week lead time across London, Essex and the South East.
