Supplier Reviews

1 / 6

“We have used this product extensively with the oldest install dating back to about 5 years ago and it looks just as good now as it did when we first installed it. We have found Millboard to be a truly superior product from both a design and install perspective. It’s easy to install, looks fantastic, and is a great substitute for real wood without any maintenance.”
