Hewn believes that the quest for safer, ignition-resistant siding should not result in sub-par products that mimic the look of wood siding. Wood siding has a long history of use in North America, and we aim to continue these generations-old traditions by developing real-wood exterior siding that is designed to meet the ever-increasing need for fire safety in our changing natural landscape.
Our Class A Exterior Pressure Treated Ignition Retardant Lumber maintains the visual look and feel of our traditional exterior cedar siding, while implementing an industry-leading fire treatment process that modifies the wood to its core. These products resist the spread of fire, helping your project meet any major fire codes present in your area, and protecting your property in ways that were previously out of reach on a commercial scale.Â
In addition to their ignition resistant properties, our treatment process has the added benefit of slowing the aging process of the wood itself, protecting against ultraviolet degradation and extending the lifetime of the material.Â
Our ignition resistant products are subjected to industry-standard accelerated weathering tests (ASTM D-2898), Flame Spread (ASTM D-84), and are verified by International Code Counsel ESR-1159 and ESL-1021.

Class A Exterior Cedar Siding contains elements that could react with metals on the building. It is recommended to use either a pre-painted baked enamel or stainless steel product for any metal on, or in contact with the building facade.
When using copper, anodized, or any other non-coated metal, please coat the surface with a quality protective enamel finish. When possible, use 2 coats of quality protective enamel finish, which will help protect the metal from reacting to the Class A product.
* These metals will only be affected if they are sitting below your Class A Exterior Cedar Siding, as the elements would come into contact with the metal via rain and moisture running downward over the face of the building.
All Cedar Siding must be installed using only Stainless Steel fasteners.
For any questions or concerns about using decorative metals with our Class A Siding, email us at info@hewn.com.
