Expert Verdict — Reviewed by the SuperArbor Pro Desk
On conditioned buildings, a thermally broken hatch pays for itself by cutting the heat loss and condensation problems typical of standard aluminum hatches. Verify the required clear opening for the equipment you are moving before choosing between the 36 x 36 E and 36 x 54 NB sizes. During install, use the Bil-Clip system to terminate the single-ply membrane into the curb and confirm the positive latch engages for security and wind uplift.
Roof hatches are floor openings during installation; guard the opening, install the hatch ladder or safety rail system, and follow fall protection requirements on the roof.
