Lacuna folding doors: Danish design with German engineering
The Danish Lacuna bifolds blur the boundaries between inside and out. When your bifolds are open, it’s like sitting outside – but you’re sheltered from the sun and drizzles. In winter, protected by the glass panels, you still have the full pleasure of those garden vistas.
Lacuna supplies a durable, dimensionally stable door in Danish Design -and of course with unrivalled u-values and airtightness.
Let the light in and let Lacuna help you to even passivhaus performance on your project.
Here are a few notes on the specification and some references:
– 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.
-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 2800 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.
-Painted to match other timber and alu systems.
-Security tested to EN1627-30 and Pas 24.
-Delivered within 5-7 weeks and easy and quick to install.
