Slim Sightlines

When it comes to sleek and slim sightlines, nothing beats the strength and slimness of modern aluminium frames. Unlike other older window materials, our aluminium windows and doors are capable of offering gorgeous views without sacrificing reliable security and safety. 

Whether it’s a bifold door, sliding door, or flush casement window, each system can provide crystal-clear views that flood homes with natural light. Not only can a sleeker profile allow for more space for bespoke double glazing, but it can also lead to a lower maintenance design. Homeowners can appreciate the beautiful, lightweight elegance of our aluminium doors and windows for years to come.

Robust Security

Aluminium is not only a durable metal that is incredibly resistant to rusting, but it is also lighter than steel, meaning homeowners can benefit from excellent security without affecting the overall performance of their windows or doors. 

Many of the AluK systems that we supply are PAS 24 certified, which means that they have been rigorously tested to pass modern security standards. AluK aluminium windows and doors don’t warp or bend, and their impressive weather resistance can withstand anything the UK weather can throw at them.

Thermally Efficient

All of our aluminium products can come in a range of glazing thicknesses, but every one of our windows and doors comes with double glazing as standard. Each aluminium profile contains hidden polyamide thermal breaks to ensure optimal thermal performance. 

Homeowners can stay warm, secure, and comfortable all year round thanks to our windows’ ability to retain heat and keep out cold draughts or leaks. Many of our aluminium windows can reach U-values as low as 1.7 W/m2K and have a Class 4 air tightness rating.

RAL Colours

Colours have come a long way for aluminium over the years, and we’re proud to offer a large catalogue of durable and vibrant RAL colours for our aluminium doors and windows. These colours are highly scratch-resistant and can last for years without any repainting, varnishing, or sanding. Homeowners and businesses alike can avoid constant maintenance and simply enjoy beautiful, colourful windows or doors.
