Insulated Roller Doors Spiral 80 Special Application

Spiral 80 Special Application are roller shutters developed with the specific characteristic of maintaining high insulation. This insulated door guarantees good sound insulation.

The winding patented circular spiral is made of high density polyethylene and the curtain is composed of aluminum panels or double wall steel with high thermal-acoustic insulation. The winding space is very low. It does not require anchoring to the ceiling.

Spiral door ISO 80 Special Application is suitable for both internal and external applications.

Spiral 80 Special Application Cold Room are used in various sectors, from painting plants to the cold chain. Discover all the door solutions for industrial cold rooms.
