s_enn Shading System

Product Description

Developed specifically for exterior installation, s_enn® features thin, lightweight, retractable stainless-steel panels that roll-up like a standard fabric roller shade. When the sun is at an angle of 20 degrees or higher, placement of the rods can block direct light while offering a nice view-through. Tested in wind tunnel speeds of up to 80 mph (126 kph) with no damage makes s_enn® perfect for the exterior of high-rise buildings.

ANSI/WCMA A100.1 Compliance

If clutch-operated roller shades are installed in an environment where it's possible that young children will be present, they should comply with ANSI/WCMA A100.1, the Standard for Safety of Window Coverings.

If the shades that you purchase need to comply with this standard, it is your responsibility to inform Draper and opt-in to receive compliant products at time of order.

Compliant window shades will include:

  • Pre-installed spring-loaded chain tension device with bead chain threaded through it
  • Approved permanent warning label attached
  • Approved mechanical fasteners for the tension device included

If the tension device is not installed properly, or becomes unattached from the mounting surface, the shade will be rendered partially inoperable. If installed properly, the tension device will prevent the creation of a hazardous loop and will maintain tension on the bead chain. The tension device and label require tools to be removed.


The testing required by the WCMA for products to comply with safety standard A100.1 includes:

  • UV stability testing - AATCC Test Method 16 for UV Stability
  • Impact testing - ASTM D5420
  • Bead chain durability testing
  • Operation cycle testing - 3,000 cycles per the standard

Draper's spring loaded tension device passed the requirements of these tests.
