Exterior
Elevate your outdoor projects with our range of moisture-resistant exterior grade plywoods.
Exterior grade plywoods are ideal for outdoor situations that involve high levels of moisture. We stock Marine Fir, MDO, & T1-11, all in varying thicknesses. Marine Fir is commonly used in high moisture and nautical applications. MDO is often referred to as “Signboard” due to its frequent use as signage. T1-11 plywood is most commonly used as siding on homes and sheds. Other on center spacings can be special ordered.
