The DUAL-AIR is heavy-duty folding door designed for large and extra-large applications.
It is suitable for exposed industrial units, waste transfers, aggregate and agribulk facilities, aviation hangars, recycling plants, shipyards and more, ensuring optimum performance in demanding environments.
With superior wind load resistance, the door is ideal for exposed industrial facilities subject to challenging weather conditions.
The DUAL-AIR folding door also offers excellent thermal insulation and acoustic properties, significantly improving energy efficiency and reducing noise pollution.
High Wind Resistance
This large fold up door is engineered to withstand even the most challenging weather conditions, including heavy winds in exposed locations.
Key features:
Heavy-Duty Wind Bars – The DUAL-AIR is reinforced with robust metal wind bars. These are essentially stiffeners, preventing the curtain from being pushed inward and providing rigidity in windy settings.
Track System for Excellent Stability – The door’s two curtains are positioned within a track system on the side legs, preventing them from being displaced by high winds. This ensures increased stability, as the door’s curtains are tightly restrained within the tracks.
High Wind Class Rating – With the integrated wind bars and track design, the DUAL-AIR can protect against wind loads up to class 4.
Made for Large Openings
The DUAL-AIR® fold-up door is engineered to accommodate extra-large openings with dimensions up to 15 m wide x 8 m high. This makes it suitable for the following:
Aviation Hangars – The DUAL-AIR fold up door provides robust, efficient storage in exposed aviation environments while accommodating the movement of large aircraft.
Shipyards – Ideal for large vessels and equipment stored in coastal areas subject to high winds.
Waste and Recycling Facilities – The DUAL-AIR can accommodate large vehicles transferring waste while creating an effective barrier to odours and insects.
Aggregate & Agricultural – The doors can withstand the harsh, abrasive nature of aggregate environments while providing access for large vehicles. Its large dimensions also make it suitable for storing and distributing a high volume of agricultural and aggregate bulk goods.
Thermal and Acoustic Benefits
The door is composed of three layers: a PVC curtain – ventilated air chamber – and another PVC curtain. This ensures excellent thermal insulation while preventing noise from travelling.
Key benefits:
Improved Insulation – The air chamber helps to prevent cold entering the building, maintaining a stable temperature and improving conditions for staff during challenging winter months.
Effective Sound Barrier – Just as it insulates against cold, the door’s air chamber acts as an effective sound barrier. This makes the door ideal for separating noisy working environments from quieter spaces.
Energy Efficiency – As the DUAL-AIR prevents cold air leaking into the building, you can enjoy improved energy efficiency – and lower energy bills!
DUAL-AIR® FAQs
What’s the difference between the DUAL-AIR folding door and GS Doors’ FOLD-UP folding door?
The FOLD UP folding door is lighter, making it better for a higher volume of transit. The DUAL-AIR is not as fast but covers larger dimensions.
How much wind resistance does the DUAL-AIR have?
The DUAL-AIR is available up to wind class 4, depending on the size. Please speak to a member of our technical sales team to find out more.
Can the DUAL-AIR have windows?
Yes, the DUAL-AIR can have windows. The number of windows depends on the size of the door.
