Lacuna bifold door specialist

Lacuna

Lacuna specialises in bespoke timber bifold doors made in Denmark. Inward- and outward-opening configurations can open up to 90% of an aperture while retaining the airtightness, insulation and security needed from a high-quality external door.

There was no doubt. Lacuna was by far the most beautiful and the best quality.

Why we work with Lacuna

Within the Eco Home Windows range, Lacuna is reserved for bifold-door projects. We specify it where the architectural priority is a genuinely wide opening combined with timber character and strong year-round performance, and where the supporting structure, threshold and installation can be resolved correctly.
