Installation notes
Sealant: apply behind both side and top flanges only — no sealant behind the sill flange. Sash tracks: the left side track is deeper to accommodate the sash retention springs; nylon tracks are not permanently attached to the aluminum frames. Aluminum framing: notify Porch Windows Direct if installing into aluminum framing — color-matched self-tapping hex-head screws will be provided. Note: windows under 60" in height use 3-vent panels utilizing the 3 outer tracks.
