BF 73

Product Highlight – BF73 Aluminium Bi-folding Doors

High thermal performance and slim sight lines set the Alutech Bi-folding door aside from the competition. Engineering grade hardware allows for silky smooth opening and closing operation and contemporary sleek design.

Our BF 73 system can add huge value with its efficient thermal performance and slim profile sections to minimise visible framework and maximise the glass area. Our BF73 bifold doors are designed as a sleek modern system that is fabricator and installer friendly. Our robust running gear ensure smooth operation of the doors and minimal maintenance, with optional adjustable jamb which offers easier installs with 4mm tolerance each end.

120mm Super Slim sightline ensures maximum glass expanse to suit the most demanding residential or commercial project and location. Placing our BF 73 as slimmer than 68% of bifold systems on the market. Ensuring panoramic outside views all year round.

The BF73 system is available in powder-coated finish options of single or dual colours. Because powder coating does not have a liquid carrier, it can produce a thicker coverage than conventional liquid coatings without running or sagging. Allowing your bifolds to remain sleek and attractive for years to come.

Our thermally broken 20 mm low threshold option doesn’t only help prevent trip hazards it creates an uber flushed look, seamlessly transitioning an interior space to the outside. An optional low threshold rebate is also available. Our slimline hinges blend with 10 mm gasket gaps, making for a polished and contemporary door finish.
