DUOL wooden halls are certified with international standards - DIN, EN, PEFC, OENORM, EUROCODE, ISO 9001 and others, which is guaranty for highest quality with most economical structural design. DUOL stands for safety and economy, as well as for complete one-stop client support including consulting, engineering, production, after-sale support.
DUOL DMS™ (Double membrane system) is the most advance double membrane system available with improved thermal insulation and mechanical resistance. Thanks to excellent insulation, achieved by DMS™ there is no condensation inside the air dome.
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.
Both membranes in DMS™ technology are highly translucent, therefore the use of lighting system is not required during the daytime, creating pleasant indoor environment.
DUOL membranes are self-cleaning and highly resistant to chemicals. High and consistent transparency & luminosity reduce cleaning costs and reduce lights usage.
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.
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.
Lightweight and durable, DUOL fabrics are also recyclable. The unique industrial technology guarantees 100% of fabric components to be recycled.
DUOL wooden structures are built from natural, regrowing, sustainable material - wood. Our structures require less fossil energy in manufacture than comparable projects using other materials. DUOL wooden structures covered with latest membrane technology are durable and energy efficient. This saves energy and minimizes emissions. Additionally, timber contributes to the reduction of CO2 and can be thermally recycled at the end of its utilization phase.
Air Supported Structures are an ideal solution for the seasonal or permanent coverage of one or more tennis courts. The particularly quick erection of the Tennis dome and its equally rapid dismantling that leaves no visible traces allowing for temporary or permanent coverage, thereby increasing investors’ profit levels. The excellent insulation characteristics of the double fabric membrane provides players with ideal playing conditions and protects them from the weather.
DUOL prefabricated halls are designed as lightweight mobile prefabricated halls - temporary or permanent buildings. Our prefabricated halls are delivered with DUOL innovative insulation system and they offer the best price and utility value ratio. These prefabricated halls are a progressíve alternative to conventional hall systems.
