What Are Millboard® Envello Cladding Aluminium Horizontal Starter Trims Used For?
Millboard® Envello cladding aluminium horizontal starter trims provide a precise and secure starting point for horizontal cladding installations, including the Envello Shadow Line+ and Board & Batten+ ranges.
Manufactured from durable aluminium, these trims offer a strong, long-lasting base, ensuring accuracy and stability from the very first board

Millboard® Envello horizontal starter trims are installed at the bottom of the battens on your wall to create unity between cladding boards, guaranteeing a level and straight finish.
It's crucial that the starter trims are fitted level to ensure your cladding project is in line and accurate. Using this method will enhance the aesthetics of your cladding project and increase the structural integrity of your installation.
Please note that the end of the cladding board will be lower than the starter trim, so take this into consideration when setting the height of the trim.
The Shadow Line+ cladding installation guide or the Board & Batten+ cladding installation guide contains more detailed information on how to install your starter trims along with your cladding boards. You will also find a handy list of tools and PPE, storage and aftercare advice.
