Warmcore Bi Fold Doors

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

High 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 efficient 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.

Double or triple glazing

Warmcore doors can be glazed with 28mm double glazed units or 44mm triple glazed units. Glazing can be carried out with a choice of aluminium beads for a neat internal finish.

We recommend celsius glass, our exclusive range of high performance glass. Celsius clear is specially formulated for vertical glazing and offers an impressive thermal performance to complement warmcore.

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.
