heroal RS 41

Tight Winding Slat with Wide Coverage Width

The heroal RS 41 has a large coverage width (1.61 inch) and narrow nominal thickness (0.33 inch), which means that it winds up very tightly and is best suited for use in small roller shutter boxes (Ø 7.25 inch barrel diameter with a curtain height of 8.25 ft). The extremely durable roller shutter slat with low weight (0.76 lb/ft²) fulfils wind load values of resistance class 3 with element widths up to 9.5 ft.

Design Options

  • Potential total U factor value improvement of up to 43 percent
  • Highly weather-resistant surface with 2-layer thick coating
