"I BELIEVE IN OPENING UP TO SOMETHING GREAT"

- Henrik BrunsøCEO

The dream of opening up your home and letting nature in is the basis for Lacuna’s manufacturing of folding doors in Langeskov on Funen today. The fact that the folding doors last for 30-50 years is the result of continuous product development, a careful selection of materials and the aim of being the best folding door manufacturer in the world.

STRICT RESEARCH& CERTIFYING


In addition to complying with industrial standard tests, Lacuna also performs its own extreme tests for moisture absorption, dimensional stability and insulation of the folding doors. Furthermore,our prodcts are tested by third parties in order to ensure full transparency of the product’s performance. We are therefore proud to call Lacuna’s folding doors the world’s tightest folding doors.

SUSTAINABILITY


We care about the environment. All materials used by Lacuna are carefully selected so that the cradle-to-cradle mindset is present in everything we do.

Insulation is also essential to ensure a green and sustainable future. You can build a low-energy house and save on both heating costs and CO2 with our folding doors.
The insulation is significantly better than average. The insulation value is measured in “Uw”, where a smaller number means better insulation. A normal double-glazed energy-saving window has a Uw value of 1.3 to 1.5. Our products, fitted with comparable glass, have a Uw value of 1.0-1-2, which means up to 30% less energy consumption.

EASY, LOW-COSTINSTALLATION


In addition to the energy concerns,the durability and the sophisticated finish, Lacuna’s products are fitted with a revolutionary and patented top frame system where the track is integrated into the top frame itself. The system is more accurate than other systems, saves money for mounting boards and gives a better finish.

A LACUNA FRAME AFTER4 MONTHS IN THE HARBOUR


A good folding door that can last for 50 years is very dependent on dimensional stability. In this video we show one of the many tests we perform at Lacuna, to ensure our products meet yours and our expectations. This door frame is made of TMT Composite®, which is manufactured of heat-treated beech. After 4 months in the harbour, the video shows that it has expanded by 0.4 mm and that the paint has not cracked.

DANISH DESIGNGERMAN QUALITY

All Lacuna products are designed and manufactured at our factory on Funen in Denmark. Here we think Design in Danish and Quality in German. The Lacuna folding doors are certified as the world’s tightest and most well-insulated.

The folding doors are built to operate at temperatures from -50 to +60 degrees Celcius, and we have tested the resistance to wind and water during hurricane-level winds at speeds up to 280 km / h. Lacuna’s products are designed to last 30-50 years – and possibly more.

The Danish Technological Institute (DTI) has tested our products for extreme weather, insulation and security, to give our customers peace of mind during extreme wind and weather conditions. Lacuna folding doors are designed with double or triple sealing and are certified in accordance with RC2N (EN 1627-30) requirements for burglary protection.
