At Lacuna we focus exclusively on bifold doors and aim to make them perfect. Our Danish Design doors should be part of the furniture: narrow frames painted completely smooth in any colour, complemented with marine-grade handles and hinges. We supply a lasting, totally stable and airtight door with unrivalled u-values.

A few notes on the specification:

  • Superb durability and insulation -Our FSC certified German TMT composite has a durability equal to teak, and system u-values which can be used in passiv haus projects.
  • Air and watertight – The double/triple sealed doors have passed the highest test available for wind: Air permeability EN 12207 – Class 4 at +/-600 Pa and water tightness: EN 12208 – Class E1200
  • No repainting for 25-50 years in normal conditions. The paint on thermally modified timber composite lasts longer without maintenance than on timber-alu products, as the TMT composite adopts the characteristics of a composite or fibre-glass and do not extend nor retract when exposed to moisture or temperature.
  • Slimmest profile available of any timber folding door -Only 56 mm per door frame giving a frame to frame width of 117 mm.
  • Large openings -Up to 2700 mm height and 6000 mm width.
  • Highest quality ironmongery -All hardware is in Danish designed marine grade materials, so they will not rust even on a sea front location.
  • Lacuna only manufactures folding doors, and uses skilled carpenters and CNC machines to give the precision, which is required for folding doors to work properly.
  • Security tested to EN1627-30 and Pas 24
  • Delivered within 5-7 weeks and easy and quick to install.
