5/4x4 Red Balau Shiplap Soffit

This 5/4x4 Red Balau soffit board (Shiplap profile) combines the rich grain of Red Balau (Bangkirai) with 1,580 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.
