Why Use a Vented Starter Trim?

A vented starter trim plays a crucial role in any external cladding system. Installed at the base of the wall, it supports the first cladding board while allowing air to circulate behind the cladding. Proper ventilation can help reduce moisture build-up and contributes to the overall effectiveness of the cladding system.

The Universal Fortex Vented Starter Trim is specifically designed to make installation straightforward. Once fixed in place, the first board hooks onto the trim, creating the correct starting position for subsequent cladding boards.

Applications

Ideal for:

• Residential exterior wall cladding

• Garden buildings and annexes
