Benefits of our Siding
Strong but Lightweight
Envello Siding is crafted from a blend of limestone and fiberglass, offering exceptional durability paired with lightweight insulation.
This relative lightness makes Envello easier to install than many other systems—often eliminating the need for structural reinforcement.
Like real oak, but better
Old-growth oak is too valuable to harvest, so we’ve created molds from antique boards to produce an unmatched replica.
By using a variety of boards in our mold-making process, your wall gains subtle grain variations without noticeable repetition—resulting in a look that’s strikingly close to the real thing.
Distinctive designs
Envello Siding complements a wide range of architectural styles—whether you're looking to make a bold statement or seamlessly match existing structures.
Both our Shadow Line and Board & Batten profiles can be installed vertically, horizontally, or even mixed for nearly endless design possibilities.
Made in Briatin, and warrantied
Envello boards are resistant to fading, warping, splintering, and impact from hail or wind-driven debris.
Because Millboard contains no wood, it won’t attract termites or succumb to rot—ensuring your siding remains a source of pride for years to come.
Fire performance
The Shadow Line+ siding boards have been tested to BS EN 13501-1 and carry a classification of D-s3, d0. The Board & Batten range is also manufactured with fire retardants in its composition; however, it is not fire-rated and does not carry a formal 'reaction to fire' certification.
Determining whether Envello Siding is suitable for a specific application or location is the responsibility of a certified building professional—such as a building inspector, fire officer, or insurance assessor. Millboard accepts no liability for incorrect specification, application, or installation in areas that do not comply with local or national regulations.
It is the installer’s responsibility to consult the most current fire safety guidance for the relevant country or region.
