"Air leaking into and out of the wall, ceiling, and floor systems can carry water vapor that will condense within the framing cavities. Air movement carries significantly more moisture than vapor diffusion. This condensed water can then cause mold growth and rot within the cavities, shortening the life span of the structure."
- U.S Dep't Of Energy (DOE)

Installation Instructions

1) Remove lid from frame

2) Install 3/8 OSB/Plywood into frame to form insulation dam

3) Fasten aluminum frame to bottom of truss and fasten insulation dam to truss side

4) Drop in insulated lid

5) Tape and drywall into metal edge of frame

6) Prime and stipple lid along with ceiling finish

Test Specifications

ASTME283 AIR LEAKAGE Single Panel (CSA A440 Test Rating) - A1
Double Panel (CSA A440 Test Rating) - A2

The test measures the air flow rate through an attic access subjected to a positive static pressure differential of 75Pa. This pressure difference corresponds to the pressure exerted by a 40Km/hour wind acting from the interior side of the attic hatch.

"A 1/4" gap around the perimeter of an attic hatch can potentially leak the same amount of air supplied by a typical bedroom heat duct (-100CFM)."
- U.S. Dep't Of Energy (DOE) Technology fact sheet

The first and only attic hatch that meets and exceeds Canadian National Building
Code requirements.
