QUALITY AND ENVIRONMENT-FRIENDLY BI-FOLD DOORS FROM LACUNA.
Our products are made to last 50 years or more. Lacuna uses exclusively long-lasting FSC-certified wood in our production and were the first Danish window-maker to be FSC-certified in Denmark. In the long run the lowest price is for the longest lasting product. We consider Danish design, German quality and minimal energy consumption as quite natural because Lacuna products made today will also be energy-friendly in 10 or 20 years compared to other window products. Wether you choose heat-treated painted beech or oiled mahogany – Lacuna only uses sustainable wood.
Our patented system is built insisting on a high degree of insulation achieved by double insulation seals in the frame and triple insulation seals in doorjambs. Lacuna bi-fold doors are built to function from -60°C to +50°C.
For this reason people enjoy our products from far north of the polar circle to far south in Africa. Good insulation works both ways!
In all our painted products we use heat-treated beech that does not expand in humidity. Heat-treated beech is just as resistant as teak. It has a higher insulation value than pine, fir and other nonmodified woods. Since heat-treated beech does not absorb humidity, the paint will not crack and normally a Lacuna bi-fold doors will not need repainting for 20-50 years depending on its exposure to the weather.
With Lacuna we offer taylor-made bi-fold doors, folding windows and French doors.
We are able to adjust our products as to colours, etc., so they match the style of existing windows and doors in your home.
A functional, elegant and energy-saving design makes Lacuna bi-fold doors generously admit natural light.
