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.

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 efficienct 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.

High strength construction

From the unique 5 point lock, designed to run the full length of the door sash, to the high strength hinges and rollers; each element of the WarmCore door combines to ensure optimum security. WarmCore’s aluminium construction,custom-made roller assemblies - sitting deep within the top and bottom tracks - and extruded aluminium hinges make them inherently strong and secure. Added security features such as integral dog bolts bind the door sashes together when closed, protecting against forced entry. A custom designed door lock, available on no other door system, uses a 5 point locking system with 3 opposed hook locks and twin shoot bolts - that engage fully into the aluminium top and bottom tracks - helping keep you and your family safe and secure.

Every WarmCore door is independently certified to PAS24:2012 the benchmark in enhanced security performance requirements for doorsets and windows in the UK.

Flexible threshold options

Sill options include a WarmCore standard threshold with integral sill, or standard threshold with an additional 150mm thermally-broken aluminium sill.

The Part M compliant low threshold design is thermally-broken aluminium and optional ramps and cover trims can be used internally, externally or both, depending on requirements.

Part M compliant low threshold can also be installed without any ramps, so that flooring can be laid up to the edges of the threshold or the threshold can be neatly set into the floor to create a flush floor level through the doorway.
