Enviroshake achieves an unconditional Class A fire rating

What it means to have an unconditional Class A fire rating - and why other products can’t match it

Ontario, Canada, 15 November 2019 – Composite roofing products are highly sought after for their authentic, natural appearance and unmatched performance. But as their compositions include plastic and/or rubber, they have long struggled to obtain fire ratings higher than Class C. As a result, composite roofing companies often disguise their Class C fire ratings by advertising Class A roofing systems” that depend on supplementary products, such as underlayments, which can be complicated and expensive to install. 

This is what sets Enviroshake apart. Enviroshake’s newly available unconditional Class A fire rating (ASTM E108) does not require the expensive supplementary products other materials rely on to achieve its best-in-class fire rating. Instead, its intensive scientific testing and state-of- the-art engineering processes have developed a product that boasts an unconditional Class A rating independent of such “systems.” This is especially exciting news for property owners in areas with an increased risk of wildfires, such as California – and it offers Enviroshake a distinctive competitive edge. Furthermore, this engineering breakthrough sets a new safety standard for composite roofing the world over.


What should consumers know?

  • Class A fire ratings are not as clear as they seem:
    • Unconditional Class A fire rating – The product itself is resistant to fire
    • Class A fire-rated roofing system – The roof is dependent on an underlayment
  • If a consumer purchased a synthetic tile with a Class A fire rating, they should reach out to the company to make sure it has an unconditional Class A fire rating. Installed without the appropriate underlayment, a tile that’s part of a Class A roofing system does not provide protection from fire.
  • Be cautious around companies claiming to have a Class A fire rating when the fire rating comes from a separate product

Here's a quick video showing some different brands of synthetic tiles burn, to see the difference a Class A fire rating truly makes when it matters most. The video has been sped up and minor visuals have been added, but it was otherwise left unedited.
