Spiral Door ISO 50 insulated roll-up doors: technical specifications

Among the most significant features of Spiral Door ISO 50 insulated shutters is the high-density polyethylene patented circular spiral winding. The cover of the damper is in double-walled aluminium or steel panels with high thermal-acoustic insulation and the possibility of inserting polycarbonate windows.

Extreme response speed, minimum displacement noise, absolute safety, upper winding with reduced overall dimensions, thanks to the special processing of the curved insulated profile make this product at the cutting edge of the industrial doors sector. In addition, no ceiling anchors are required for fixing the damper door saddle, unlike traditional quick-wound doors.

Ground impression is completely absent when the shutter is open. The last characteristic of the ISO 50 industrial shutter, but not for importance, is its very attractive aesthetics, able to provide the customer with an excellent business card of its activity. These and other innovations make Thermicroll® the leading company in design, research and development.
