Timber hall visualization

Spans of up to 150 meters with unlimited lenght and proven membrane technology have made DUOL well-known far beyond its borders. DUOL wooden halls are lighter and more competitive than comparable constructions with alternative building materials. Combination of high quality wood, covered with innovative membrane technology offer great value, high durabillity and comfort.

Woden halls - Quality is timeless
Thanks to DMS™ advanced technology, the replacement of the membrane is not required and the life expectancy is extended to 40+ years, based on tests, experiences and existing projects.

Indor light experience
Both membranes in DMS™ technology are highly translucent, therefore the use of lighting system is not required during the daytime, creating pleasant indoor environment.

Perfect whiteness
DUOL membranes are self-cleaning and highly resistant to chemicals. High and consistent transparency & luminosity reduce cleaning costs and reduce lights usage.

Fire resistance
All membranes are fire retardant, certificated by following certificates: M2/ NFP 92-507, TEST 2/NFPA 701, CSFM T19, B1/DIN 4102-1, BS 7837, B1/0N0RM B 3800-1, M2/UNE 23.727, VKF 5.3/SN 198898 and others.

Wooden structures - All weather comfort
DMS™ membrane system is designed for extreme climate conditions, for temperature range from -50 to +70 degrees. Facts are confirmed in a practice too, as DUOL’s references are installed all over the world, from Arctic Circle to hot areas of Middle East.

DUOL DMS™ (Double membrane system) is innovative double membrane system, which offers improved thermal insulation and superior mechanical resistance. Thanks to DMS™ excellent insulation there is no condensation inside the hall.

DMS™ membrane is coated with special lacquering finish like Polyvinylidene fluoride (PVDF-II) or Titanium dioxide (TiO2) which increase material quality, lifespan and are self-cleaning.

Glued Laminated Timber (GLT) is a material which does not only convince in economical and aesthetical terms but also drives the world of construction in many ways. High quality GLT is characterized by high load capacity, dimensional stability, and the manipulation of timber parts into any shape.

DUOL GLT elements are subjected to severe testing before they are considered for further application. In our work we comply with DIN, EN, OENORM, EUROCODE standard and we have an ISO 9001 certification. Numerous quality labels guarantee the workmanship of our products.
