Welcome to a world of Lacuna folding doors

Over 20 years of experience designing and manufacturing custom-made folding doors tailored to your needs.

What is Lacuna?

Lacuna is a Danish company that develops and manufactures folding doors at its own factory in Langeskov. The ambition is to create the world’s best folding door – as an alternative to traditional sliding doors – opening up your entire home and bringing nature inside during the summer, without compromising on insulation, airtightness, security, design, or quality.

What is a Lacuna folding door?

A folding door from Lacuna is designed to last more than 50 years and can open up to 90% of the width – whereas a traditional sliding door only opens up around 45% of your home to the outdoors.

Henrik Brunsø, CEO

The dream of opening up your home and bringing nature inside is the foundation for Lacuna today producing folding doors in Langeskov on the island of Funen. Their lifespan of 30–50 years is the result of continuous product development, carefully selected materials, and the ambition to be the world’s best folding door manufacturer.

Danish design and production

At our production facility on Fyn, Denmark, Danish design is combined with German quality. Our folding doors are certified as the world’s most airtight and best insulated. They are developed to withstand everything from extreme temperatures to hurricane-force winds of up to 280 km/h. With a lifespan of over 50 years and documented resistance to both weather and break-ins, they meet the highest standards.

Why choose Lacuna?

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.”

Lars Blomstrøm

“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.”

Louise Pedersen

“Lacuna has delivered the most beautiful folding doors for our new bedroom. Our expectations were sky-high and were truly exceeded – we received the best service from start to finish, and every single day we’re so happy that we can open up and bring nature inside. Thank you, Henrik and the entire Lacuna team!”

Lone

“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.”
