Technology leader with innovative, environment friendly solutions
DUOL ECO Membrane, the unique membrane system from DUOL, that ensures the structural stability, excellent thermal insulation, the ultimate strength, and with an amazing flexibility at the same time.
Thanks to its outstanding insulation there is no condensation inside the air dome. DUOL ECO membrane is coated with a special lacquering finish like Polyvinylidene fluoride (PVDF-II) or Titanium dioxide (TiO2) which increases the material’s quality, lifespan, and the dirt resistance. ECO membrane is certified by independent European third-party laboratories.

ECO Basic is DUOL classic membrane system which offers DUOL high quality within your budget.
ECO Advance is the new generation of membrane system which completely eliminates thermal losses through thermal bridges. This innovative design offers higher thermal insulation and many other advantages over ECO Basic.
ECO Ultra is the latest DUOL innovation with the most advanced membrane technology. A state-of-the-art insulation system between the membranes ensures the lowest possible U-value.
DUOL Transparent membrane has an impressive 64% light transmittance and offers a pleasant indoor ambiance.
Opaque membrane ensures that AC works with maximum efficiency. It is a type of membrane that is mainly designed for extremely hot regions where sun protection is vital. The membrane withstands heat up to 70 degrees Celsius. The membrane comes in all colours, especially the beige which is the best colour against dust.
DUOL Ventilation/Heating System is pre-engineered for stability. Furthermore, it provides the desired climate conditions inside the dome. The system is completely automatically-controlled.

DUOL have accomplished many projects in the Middle East, Gulf region and other regions with very hot climates. We have installed domes in Saudi Arabia, United Arab Emirates, Egypt and other countries in Asia and South America with extreme climatic conditions. Our dome’s membrane is uniquely designed to withstand temperatures up to 70 degrees Celsius. Our domes are designed AC system ready together with high thermal membrane insulation which reduces the heat entering the dome and maintains the climate inside the dome. A ventilation system ensures the fresh air circulation inside the dome to keep a healthy, fresh and cool environment for the visitors inside the dome. The air conditioning system withstands heat up to 70 degrees Celsius.
DUOL has great experience in constructing airdomes for extreme weather conditions. We have enhanced all elements (membrane, air generators, anchoring system…) to withstand extremely low or high temperatures with strong winds and heavy snow.
LaserLed luminaries are using LED source for light emission. They are suitable for operation under most difficult sports applications. Specially designed technology for precise and high-intensity light source. System efficiency up to 210 lm/W Construction with the optical part is designed for high-intensity light source with a low glare as well as a “no-shadow” effect. The construction is made of steel and aluminum to ensure best possible heat dissipation and a long lifetime. One of the great advantages of LaserLed is its simplicity of construction where all parts can be substituted as well as the power supply being a standard one. LaserLed has the possibility of remote control for dimming purposes if needed.

DUOL SmartDome is an innovative solution for the supervision and automation of airdomes. Programmable logic controller (PLC) interacts with different airdome systems and is used for supervision, automation and control solution. Technical data and alarms are transmitted (via GPRS or LAN) and can be managed remotely. Users have easy access via a web cloud-based application where data is stored and accessed by smartphones as well. Alarms are sent to email or SMS.
Supervision, alarming and automation
Remote data acquisition
Data logging and history
Wide range of air dome monitoring/controlling/alarming systems
Why install SmartDome?
Automatisation of daily/repeating tasks
24/7 monitoring & remote control, through smartphone, tablet or computer
User-friendly and customisable interface
Every structure needs a solid foundation to keep it anchored and secure. With the DUOL advanced anchorage system, air loss around the base perimeter is significantly reduced, providing savings on inflation.
Suitable for extreme weather conditions
For permanent or seasonal use of the dome
Durable hot galvanized steel. Maintenance free
Anchoring without concrete foundation
With a ground-anchoring system, there is no need for a concrete foundation around the air dome. By using ground anchors, the air dome is anchored directly into the ground with minimal ground disruption.
Custom design possibilities
DUOL air domes can be custom-designed according to client’s specifications. Different colors, designs and
logos are possible.
Air structures can be fixed to other buildings in a variety of ways. If the need arises for a larger facility, expanding or modifying an air structure is a simple procedure and can be accomplished with a minimal disruption. Air dome can be shortened, prolonged or relocated at any time, even doors, tunnels and connections to buildings can be added additionally.
Air dome on the top of building
Air dome has a flexible design that can be installed even on top of existing buildings.
De-stratification system is mounted on the top of the dome and improves temperature distribution inside the dome – pushing the warmer air down from top to bottom. The result is lower energy consumption and a pleasant indoor environment.
As a company involved in the sports industry for more than 25 years, we have been closely linked to trusted suppliers of air dome interiors and we can deliver for you completely equipped turn-key sports object, including stands, offices, locker rooms, toilets, sports flooring, sports equipment, dividing nets etc.
