Warmcore Aluminium Bi Fold Doors

WarmCore, an innovative aluminium folding sliding door system which incorporates a radically different product design approach to deliver a new high-performance fenestration framing solution: “warm aluminium”. Designed from scratch starting with a clean sheet of paper, every ingle component has been concept sketched, detail designed, prototyped, tooled, trial installed and rigorously tested by Synseal’s unrivalled R&D team. True innovation - WARM ALUMINIUMWarmCore is a high-quality aluminium folding sliding door solution with peerless thermal performance that ensures comfort, all year round.

Superior Thermal Performance

At the heart of WarmCore products is a thermal core which significantly out-performs the polyamide thermal breaks commonly used to reduce the threat of cold bridging on aluminium windows and doors.

The result is an innovative “warm aluminium” frame construction, carefully dimensioned to provide an optimised 70mm front-to-back overall sash frame depth while ensuring market-leading thermal performance thanks to the multi-chambered insulating core.

Fully concealed multi-chambered cores substantially improve thermal performance when compared to thermally-broken aluminium doors:

  • U-value of 1.4 W/m2K with 28mm double glazing
  • U-value of 1.0 W/m2K with 44mm Triple glazing

WarmCore has been designed from the ground up to offer market leading thermal performance, protecting against future tightening of Building Regulations.

Using standard double glazing the WarmCore folding sliding door achieves a U-value of 1.5, with U-values as low as 1.0 achievable using 44mm triple glazing. The advantage against traditional aluminium doors is clear, with many struggling to meet current legislation.

Hi-Tech Elegance

Precision-manufactured with a high-quality surface finish and affording slim sightlines when installed, aluminium has become the material of choice for premium folding sliding door applications.

WarmCore doors utilise a composite of materials to ensure an end product that is energy efficiency and recyclable combined with the premium quality, structural integrity and architectural design elegance of aluminium to create a product perfect for both residential and commercial building applications.

WarmCore Design

From the rollers to the handles to the corner assemblies, WarmCore displays an elegance of design that translates into a high performance installed product that looks outstanding.

An attention to detail that goes as far as creating bespoke union mouldings for gaskets ensures WarmCore outperforms the competition.
