Internally tested for water penetration - Low Profile Saddle Sill.

Alternative 1

Inward or outward opening: No uncontrolled water entry at 3.75 psf (38 mph), subject to the following adaptations in the field:

1. Remove the gasket covering the inner channel (removal of the gasket may adversely affect the air infiltration rate).
2. Drill weep holes through the bottom of this channel (about one 1”x1/4” 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”x1/4” weep hole per panel).

Alternative 2:

Inward or outward opening: No uncontrolled water entry at 6.0 psf (48 mph), subject to the following adaptations in the field:

1. Cut part of the inside flange of the sill. Attach an additional U-channel 1 3/8” x ½” to the interior side of the sill.
2. Drill weep holes from the lower side of this U-channel to the lower chamber of the sill (about one 1”x1/4” 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”x1/4” 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 the above guidelines and in accordance with good waterproofing techniques. If drain connections are not made or are not possible, unit may leak with wind driven rain.
