Winding industrial door Air Flow

Winding industrial door with air permeability Air Flow meets the needs of separation and security, enabling easy exchange of air between inside and
outside also when the door is closed, thanks to micro perforated panels.

Thermicroll® Air Flow is constructed by a structure without fixings to the ceiling, thus providing the possibility of application also in areas where the ceiling of the building is not load bearing. The winding patented circular spiral is made of high density polyethylene and the curtain is composed of steel panels micro perforated and anti burglary. The winding space is very small and is absent the footprint on the ground when the door is open.

Features and advantages of microperforated speed doors

The main characteristics of the microperforated industrial doors are high response speed, minimum displacement noise, absolute safety and the upper winding with reduced overall dimensions. All this is possible thanks to a special machining of the curved insulated profile.

The special design of the microperforated Air Flow speed door gives it an unparalleled durability, eliminating the need for extraordinary maintenance. Ordinary maintenance operations are also very limited in time, creating important economic and temporal savings.

These and other innovations make Thermicroll® the leading company in design, research and development, and the Air Flow model a good example of an easy, fast and space-saving industrial door.

The industrial door, which uses mechanical and electrical components of the highest quality, is entirely designed and built in Italy, in one of the company’s various locations.

All our roll-up doors comply with the 12453-12445/EC and UNI EN 13241-1/EC standards and are certified as exclusive and original products, unique in strength, practicality, functionality and quality.

If microperforated industrial shutters are not the right solution for you, you can see the other models of insulated roller shutters available: Spiral 50 insulated rapid doorsSpiral 80 Special Application insulated shutters, Spiral 80 Cold Room insulated speed doors.
