Fire-Rated Composite Cladding
The Envello Shadow Line+ from Millboard provides fire protection with a real-wood look.
There are many factors to consider when it comes to choosing cladding for exterior and interior finishes. You want something long-lasting, good looking, and able to stand up to the climate and the elements. And for many, the risk of fire is a real concern.
The Envello Shadow Line+ cladding from British manufacturer Millboard is an upgrade from their standard Shadow Line that is formulated and tested to receive a Euroclass D fire rating, which indicates initial resistance to fire as well as delayed heat release from the flames. This wood-free shiplap-style cladding is created in molds that are formed using real oak for a true wood look. The composite core is made of a mix of limestone with bits of fiberglass added for structure all bonded in a polymer resin for a nonporous result. Board sizes are 7.9 in. wide by 141.6 in. long and come in five finishes ranging from light-colored Limed Oak to the darker Antique Oak (pictured below) and Burnt Cedar (above).
Currently, Outlive is the only authorized dealer in the United States, although Millboard is working on expanding throughout the country. You can purchase their cladding directly through Outlive and expect to pay around $16 per sq. ft.
