WarmCore aluminium  folding doors  were created out of a desire to combine the desirability and durability of aluminium with unparallelled insulation.
 25% more thermally efficient than traditional aluminium bi-folding door systems 

External Styling

Four external aluminium designs deliver a range of classic aesthetic styles:

1. Pencil Round2. Chamfered3. Square4. Decorative

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.

Glazing Options


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:

  1. Square all round (horizontals and verticals)
  2. Chamfered (option for verticals)
  3. Triple glazing uses 44mm TG bead all round (horizontals and verticals)

We recommend the Celsius Glass. Celsius Clear is specially formulated for vertical glazing and offers an impressive thermal performance to complement WarmCore. Click below for more Information on Celsius glass.
