DUAL-AIR® FAQs
How wide can a DUAL-AIR® door be?
A DUAL folding door can reach a maximum size of 15 meters wide and 10 meters high.
How much wind resistance does a DUAL-AIR® folding door have?
The DUAL folding door mantle is characterised internally by metal lattices that do not deform under the action of the wind. The lattice has a resistance 10 times higher than the single tubular profile.
The wind resistance class is 2 (approximately 100 km/h).
How well does a DUAL-AIR® insulate from the cold?
A DUAL-AIR® folding door has a door leaf composed of three layers of different materials: PVC – ventilated air chamber – PVC.
Air is a good thermal insulator and the thickness of the air chamber allows the DUAL ® membrane to have a thermal transmittance of approximately 2 W/m2K, 4 times lower than a PVC layer alone.
Does the DUAL-AIR® folding door also serve as an acoustic barrier?
The DUAL-AIR® folding door leaf, being made of 3 different materials, provides good noise reduction thanks to the air cushion inside the two leaves .
Can I have a 10m folding door with remote control opening?
For safety reasons, a 10 m wide DUAL® folding door cannot be automatic and controlled by radio controls.
Can I use the DUAL-AIR® door as a replacement for the folding door?
DUAL-AIR® folding doors are the evolution of folding doors because:
- They do not have significant lateral encumbrances
- They allow you to have a single closure that works both as a closure and for transit
The double tear-proof and cut-proof sheet acts as a deterrent against a possible intrusive action.
The thermal transmittance of a double sheet is still a good insulation if you want to adopt a single automatic closing solution.
High Wind Resistance
DUAL-AIR® enhances door security and fortify it against strong winds.
Its integral wind bars provide superior weather resistance against wind loads up to Class 4. Steel wheels at each end prevent curtain displacement.


Ideal for Large Spaces
The DUAL-AIR® fold-up door is engineered to accommodate large openings up to 15m x 10m, providing expansive solutions for various spaces.
External and Internal ‘dual’ curtain design ensures maximum safety.
Lifting belts positioned between the dual curtains eliminate the risk of injury during operation.
Pre-wired safety light curtains integrated within the frame detect obstacles or individuals, automatically reversing the direction of the DUAL-AIR® for enhanced safety.
Low Thermal Transmittance
The DUAL-AIR® curtain design creates an air chamber, offering optimal thermal and acoustic insulation.
