Warmcore Aluminium

Don’t want uPVC?

Then our hi tech Aluminium solution is the answer

Aluminium windows and doors are an impressive addition to any home that guarantees beauty as well as functionality. Historically however, using aluminium has meant a compromise in thermal efficiency but not any more!

We use the very latest in technology which sets us apart from our competitors.

  • Looks like Aluminium
  • The very latest technology
  • Warmer by Design
  • Architecturally appealing
  • A true British innovation

We use an exciting and innovative new aluminium system which incorporates a radically different product design approach to deliver a new high performance framing solution: “warm aluminium”.

Built around a belief that beauty doesn’t have to compromise performance, WarmCore aluminium folding sliding doors were created out of a desire to combine the desirability and durability of aluminium with unparalleled insulation. The orange thermal core – hidden away in the finished doors – is key to why WarmCore doors are 25% more thermally efficient than traditional aluminium systems.

Warmer by Design

WarmCore Aluminium has been designed from the ground up to offer market-leading thermal performance, and comfortably meets the requirements of Building Regulations across the whole of the UK. Traditional aluminium systems can force you to choose aluminium aesthetics and finish over thermal performance. WarmCore gives you both, with its innovative full width thermal core.

This unique composite construction creates the most thermally efficient aluminium product in its class. This design philosophy has produced a window system that has exceptional thermal performance, helping keep fuel bills lower and heat in your home, while retaining the sleek and architectural look of aluminium.
