Millboard® Envello Cladding Aluminium Perforated Closure Trim 3m
This Millboard® Envello aluminium perforated closure trim is specifically designed for use with Millboard® Envello cladding boards. Installed behind the boards, it protects the ventilated cavity by preventing insects and small rodents from gaining access. It also maintains essential airflow, helping preserve the performance and appearance of your cladding system. It should be used wherever there is an open entry point to a ventilated cavity.
Why Do You Need To Use Millboard® Envello Cladding Aluminium Perforated Closure Trims?
This 3m-long Millboard® Envello aluminium perforated closure trim is designed to prevent insects and rodents from entering the ventilated cavity behind the cladding boards, while still allowing essential airflow.
It can be installed in multiple areas throughout your cladding project, including at the base alongside the starter trim, independently at the top, and in conjunction with corner profiles, for effective protection and ventilation across the system.
This perforated closure trim is suited to 25mm or 50mm batten sizes and is used alongside Millboard® Envello Shadow Line+ and Envello Board & Batten+ cladding ranges.

For optimal placement, the perforated closure should be positioned between the back of your battens and the wall. This should be considered when fixing the battens. Alternatively, the perforated closure can be fixed to the front of the battens using the 20mm stainless steel fixings.
When using perforated closure trims with external or internal corner profiles, you will need to attach them to the back of your corner profiles using 20mm stainless steel screws at 200mm intervals. These are then secured to the battens at the corners. When installing a square corner trim, a similar process is followed.
For full installation instructions and a list of required tools, see the Shadow Line+ cladding horizontal installation guide (or the vertical installation guide), or refer to the Board & Batten+ cladding horizontal installation guide (or the vertical installation guide), depending on the range you’re working with.

Customer Collection Notice
Please ensure you have pre-booked your collection slot before travelling to site.
When arriving to collect your order, please report to a member of our Warehouse Team who will register your arrival and locate your goods. Once ready, your items will be picked and brought to your vehicle loading area.
During busy periods, there may be a short wait while our yard team assist other customers or complete other loading tasks. We always do our best to work within your booked collection time.
We respectfully draw your attention to the following important points:
- Loading is ultimately the customer’s responsibility. While our team can assist with mechanical loading using forklifts, we cannot handball items into enclosed vehicles. Customers must ensure their vehicle is suitable and that goods are safely loaded and adequately secured before leaving the premises.
- Sharp sheeting, metal goods, and long/heavy items may pose additional handling risks. Please come prepared with high-quality protective gloves, and any appropriate protection materials to avoid damage to your vehicle or restraints (e.g. ropes or straps). The edges of roofing sheets and metal products can be extremely sharp, and care should be taken when handling.
- We strongly recommend that customers bring their own straps, ropes, or other securing materials, as we are unable to provide these at the point of collection.
- If you are unsure of your vehicle’s load capacity, we can advise the approximate weight of your order in advance. It is your responsibility to ensure your vehicle is suitable for transporting the goods safely and legally.
- Cladco will not be held liable for any damage to your vehicle or goods once they have been loaded and leave our premises. Loading assistance is provided entirely at the customer’s own risk.
Click & Collect – Pre-Booking Required
You are welcome to collect your order from either our Okehampton (Devon) or Andover (Hampshire) site. All collections must be pre-booked in advance so your items can be picked, packed and ready for you.
Please do not travel to site without a confirmed collection time, as we cannot guarantee your order will be available.
Once your items are ready, you will receive an email with a link to book your collection slot. Please note, same-day collections are not available and bookings must be made at least two hours in advance.
When you arrive, please bring your order confirmation and follow the signage to the collection area where a member of our team will assist you.
