s_enn® Shading System

Developed specifically for exterior installation, s_enn® features thin, lightweight stainless steel retractable panels that roll-up like a standard fabric roller shade. When the sun is at an angle of 20 degrees or higher, the placement of the rods offers a nice view-through, while blocking direct light. It has been tested in a wind tunnel at speeds of up to 80 mph (126 kph) with no damage making the s_enn® perfect for the exterior of high-rise buildings.
  • Type 70 system with side guide rods: minimum width of 25” (64 cm), maximum width of 8’ 10” (269 cm), maximum drop of 13’ 1” (399 cm), and maximum area of 107 sq ft (10 sq m).
  • Type 71 system with extruded side guides: minimum width of 25” (64 cm), maximum width of 8’ 10” (269 cm), maximum drop of 19’ 8” (600 cm), and maximum area of 150 sq ft (14 sq m).
  • Standard systems can achieve a drop up to 9’ 2” (280 cm). Custom systems can have a drop of up to 19’ 8” (600 cm). The maximum width is 8’10” (269 cm).
  • Two side guide options: stainless steel or extruded aluminum.
  • Standard systems available in round or rectangular extruded aluminum headbox style. Custom systems supplied with formed aluminum headbox.
  • Can be installed on vertical or inclined glazing, and can operate on slopes up to approximately 10° from vertical.
  • Withstands high wind speeds. Has been tested up to 78 mph (126 kph) and is warranted for wind speeds up to a maximum of 56 mph (90 kph.)
  • Blocks direct light for sun angles higher than 20° off horizon.
  • For coastal installations with potential exposure to higher salinity, ask about Draper’s s_enro® system that features aluminum instead of stainless steel construction.
  • System can be used on the interior or exterior of a building.

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.
