About Millboard® Envello Shadow Line+ Cladding
Millboard® Envello Shadow Line+ cladding boards provide a luxurious, contemporary alternative to classic timber cladding, with every board moulded by hand using timber masters for an organic, woodgrain finish. Each Envello cladding board features secondary colours throughout the grain to replicate the variance you would get in natural timber products.
In addition to the unmatched aesthetic appeal, this Millboard® cladding board is tough, durable and lightweight. The surface of the board is resistant to scratching and provides resilience to fading and weathering due to UV rays and weather events. The solid core is composed of natural minerals bonded together in a polymer resin, reinforced by renewable biopolymers and fibres for increased strength and superior resistance from rotting and warping.
Suitable for most low-rise residential and commercial applications, subject to building regulations, it provides a striking, decorative façade when installed on an existing structure. The range is inspired by elegant natural tones, such as golden oak, salt blue, and sage green, making Millboard® Envello Shadow Line+ cladding a sophisticated choice for contemporary and traditional designs alike.
It also helps improve thermal performance year-round, offering added comfort in both summer and winter.
The Shadow Line+ cladding is fire-rated to Euroclass D (BS EN 13501-1) for additional assurance and quality.

For help on how to install your Millboard® Envello cladding boards, you can refer to the installation guide, which also includes advice on storage, tools, cutting and aftercare.
Millboard® Envello Shadow Line+ cladding boards come in the following colours: Limed oak, burnt cedar, antique oak, golden oak, smoked oak, salt blue, anthracite, coppered oak and sage green.
Due to the natural oak moulds and pressure used in the production, a minor variance in the board's dimension is unavoidable. For consistency within the tolerances, the boards are calibrated. Tolerances in manufacturing are as follows: Width of ± 2mm, length of ± 5mm, thickness of ± 2mm.
Millboard® Shadow Line+ external corner profiles and internal corner profiles are available, as well as Millboard® Envello reveal boards, in matching colours for a seamless exterior. Envello colour head screws can also be used to fix through your cladding face.
Millboard cladding is UK-manufactured and backed by a 15 Year Limited Structural Cladding Warranty. Find out more information here.
