DUOL experiences in membrane technology joined with Europe’s most modern CNC wood-processing production. 

With more than 25 years experiences in sport halls, with more than 1500 covered facilities all over the world and full service support DUOL is partner you can trust. DUOL innovative membrane technology offers perfect insulation, great energy savings, long durability and perfect aesthetic performance. 


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.


Technology is on our side

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.

DUOL has built Indoor Football Stadium for Football Federation of Kazakhstan. One of the biggest wodden hall


Why DUOL wooden structures: 

• Europe most modern CNC wooden production
• Complete one-stop solution, quality control in all phases 
• The high-level of factory wooden pre-fabrication reduces assembly time and costs in the site
• 25 years experiences 
• Worldwide references
• Innovative DMS double membrane system 
• Certified solutions


Innovative thermal insulation

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.






Advanced membrane coating

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.


  • 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. 


Wooden hall: Quick, safe, ecological

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.

DUOL Wooden structures: 
• Long-standing experience in GLT structures
• Ultra-modern and high-tech manufacturing facility 
• Internal and external quality assurance (Certified ISO 9001:2015)
• Expertise of an experienced team of structural engineers, civil engineers and skilled workers 
• Turn-key services



Wooden hall Engineering / construction

CAD-competence and project-optimizing with internationally known engineers economic, ecological and esthetic solutions, individual design.



Wooden hall customization

High precision and room for architectural creativity are guaranteed as the production process is CNC controlled from beginning to end.

Wooden structure - Complete turn key project

As company involved in sport area for more than 25 years, we have the knowledge to offer completely equipped sport arena. We are closely linked to trusted suppliers of sports equipment and sport floorings, offering highest quality products, designed using the latest technology and certified by international sports associations.


Environmental Commitment

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.
