Safe. Sustainable. Cost effective. We meet every aspect of our customers' needs

The air-supported structure is an autonomous object, meaning that in an emergency situation it sustains itself. The emergency unit provides stability to the dome in case of a blowing unit failure or in case of an electricity break-down. Each dome is equipped with a certain number of emergency exits according to the dimensions and purpose of the dome. The fabric is fire-retardant and all air dome elements meet local standards. The unique structural design of the air dome allows it to withstand heavy winds and snow and, unlike conventional buildings, the air dome is earthquake resistant. DUOL’s product is certified with ISO management system 9001 as well in compliance with standard EN 13782, which means that we keep in all calculations reserved as stated in this standard.
