Open up to views, light, fresh air, and nature. A Lacuna folding door meets the highest energy standards and ensures a comfortable indoor climate.

Why choose Lacuna?

Tests & Certifications

Lacuna doesn’t settle for standard testing. Our folding doors are tested at the Danish Technological Institute, in our own extreme tests, and by independent third parties abroad for moisture absorption, dimensional stability, and insulation. This ensures full documentation and helps make Lacuna folding doors the world’s most airtight.

Sustainability at the forefront

At Lacuna, care for the environment is an integral part of everything we do. Our raw materials are carefully selected, and our folding doors are developed with a focus on high insulation, reduced heat consumption, and a lower CO₂ footprint. With a Uw value of 1.0–1.2, they can help reduce energy consumption by up to 30%.

Easy installation, cost-effective fitting

Lacuna’s products combine energy efficiency, durability, and a refined finish with a revolutionary patented top-frame system. Here, the running track is integrated directly into the top frame, allowing for more precise installation, fewer materials, and an even better-looking result.

When quality needs to be felt

Read why customers choose Lacuna for their homes and building projects.
“Lacuna doors are top quality. Quite simply, Lacuna was recommended by Paw, our architectural advisor from We Make Space, and after looking at various folding doors, there was no doubt. Lacuna was by far the most beautiful and the best quality. We bought and had a three-panel door installed by Hardy from Dansk Vinduesservice ApS. Professional and excellent advice, and the installation was spot on. We felt in safe hands all the way through. We’re looking forward to a summer with our folding door wide open.”

“We have just had a Lacuna folding door with four sections and a double door delivered. The guidance we received before ordering was excellent. Once the doors were ready, we were able to have them delivered on the day that suited us, and since we were not quite ready for installation, they stored the doors for us until we needed them. The doors arrived as planned, and the carpenter was very impressed by how clear the assembly instructions were, as well as by the quality of the materials. They are very beautiful and sturdy doors. They glide extremely well, and the service has been absolutely top-notch. I can only recommend spending a little extra money to get doors of the very best quality — doors that we know will last.”

“From the very first phone call until now, we have received the very best service. We were given really great advice on which door to choose in order to get the most out of the room it was going to be installed in. We also chose to use the company Lacuna works with for measuring, and we are so pleased that we did. They have also been a great help with everything we needed. We can therefore only recommend buying from them again. Thank you so much for all your help. We look forward to replacing the other doors in the house as well, and we know that you will be there ready to help.”
