Description
The Millboard® Envello Aluminium Vertical Starter Trim (2.5m) is an essential component when installing Millboard® cladding vertically. Designed to create a straight, level starting point, this trim helps ensure your Shadow Line+ or Board & Batten+ boards align accurately from the very first board.
Used at the base of the installation, this genuine Millboard® accessory provides a secure and durable foundation, giving your cladding project a clean, professional finish from the ground up.
Why Use a Vertical Starter Trim?
When cladding vertically, the first board sets the line for everything that follows. This aluminium starter trim:
-
Creates a precise, level base for vertical installations
-
Improves alignment and overall visual finish
-
Adds strength and stability at the bottom of the cladding run
-
Helps maintain even spacing between boards
Suitable for use with:
-
Millboard® Envello Shadow Line+ cladding
-
Millboard® Envello Board & Batten+ cladding

Installation Guidance
Vertical starter trims are fixed:
-
At the bottom of the battens
-
Using perforated closure trims
-
With 20mm stainless steel screws
This creates a strong, straight reference line for the first cladding board and helps maintain alignment across the full installation.
Important:
The ends of the cladding boards will sit slightly lower than the starter trim – this is by design and should be considered during layout.
For full guidance, refer to the official Millboard® Shadow Line+ or Board & Batten+ vertical installation guides.
Compatible Fixings
For installation, use:
-
Millboard® 20mm stainless steel cladding screws
