Lacuna Bifolds

Just a few notes on the specification:

• Superb durability and insulation -Our certified German TMT composite has a durability equal to teak, and system u-values which can be used in passiv haus projects.
• 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.
• 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.
• Large openings -Up to 2750 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.
• Top hung system, which allows for a beautiful threshold that doesn’t need careful cleaning for the system to work.
• 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.
• Painted to match other timber and alu systems.
• Security tested to EN1627-30 and Pas 24.
• 10 year guarantee.
• Delivered within 5-7 weeks and easy and quick to install.
