Reserve® Wood Extra®

Enjoy the natural beauty and craftsmanship of an Extira wood door that delivers enduring style and performance. Extira is an eco-friendly wood composite that resists moisture, rot and termites. Engineered exclusively for outdoor use, it outperforms MDF and many wood species. Extira carves, routs and fastens like wood, giving you the freedom to create a one-of-a-kind door. Choose from modern, carriage house, or classic panel designs.



Paint grade Extira is a patented composite with outstanding strength and dimensional stability. Made from sustainable materials including unused commercial timber and resins, the density and durability of the substrate makes it easy to incorporate custom details like deep V-groove patterns as well as arches and curves. The result is a design that often isn’t possible with other molded materials or steel.

Extira doors are built in three sections, instead of four, allowing for proportionally larger window sizes.
