Expert Verdict Reviewed by the SuperArbor Pro Desk

A vented starter strip like the SV-3 is cheap insurance against rot at the lowest course of siding, where water collects behind cladding. Run it continuously along bottom edges and above openings, and pair it with flashing and a weather-resistive barrier for a complete drainage system. On fiber cement jobs, confirm the vent height fits the first-course reveal.

Cut plastic edges can be sharp; wear gloves and eye protection when cutting and fastening vent sections.
