Low Profile Saddle Sill, Standard Flush Sill
Type of Test Inward Opening Units Outward Opening Units

Water Penetration:
ASTM E-547-86

Internally Tested

Not applicable for
standard flush sill

No uncontrolled water entry @ 3.75 psf (38 mph) subject to the following adaptations in the field:

  1. Remove the gaskets covering the inner channel.
  2. Drill weep holes through the bottom of this channel (about one 1" x ¼" weep hole per panel.)
  3. Drill weep holes through the bottom of the sill or lower front face of the sill to drain water collected to a lower point (about one 1" x ¼" weep hole per panel.)

Please note that due to varying site requirements and conditions, these sills will not be prepared for drainage by NanaWall Systems, Inc. If this drainage system is desired, we recommend that a qualified professional construct this system on the project site strictly in accordance with instructions provided by NanaWall Systems, Inc. and in accordance with good waterproofing techniques. Note that in some applications drain connections may not be possible.
