1x4 Cumaru Shiplap Soffit

This 1x4 Cumaru soffit board (Shiplap profile) combines the rich grain of Cumaru (Brazilian Teak) with 3,330 Janka hardness, making it ideal for exposed eave linings and covered ceilings that endure for decades. The overlapping shiplap profile sheds water naturally and creates a classic, weather-resistant look for eave linings, ceilings, and covered areas.
