Why Use a Vent Starter Trim?
The trim provides a straight starting point at the base of the cladding installation. It also includes ventilation slots that allow air to move behind the cladding boards.
As a result, the profile helps create the ventilated cavity required as part of a correctly installed exterior cladding system. Freefoam states that a vent starter trim should be used on every cladding installation.
