Our exterior-grade waterproof OSB board is specially developed for outdoor and humid building environments. Adopting high-molecular waterproof phenolic glue and integral waterproof treatment process on the board surface and edge, this OSB board effectively blocks moisture penetration, solves the problems of ordinary wood panels such as easy swelling, mildew and deformation in humid weather. With excellent weather resistance and dimensional stability, it can adapt to long-term outdoor wind, rain and temperature changes, and is the most reliable exterior building substrate material for architectural exterior wall and roof projects.
01
Professional Waterproof & Moisture-Proof Performance
Overall waterproof treatment of board body and edges, low water absorption, no swelling and delamination in humid environment, stable performance in rainy and snowy weather.
02
Strong Weather Resistance
Resists ultraviolet radiation, temperature difference change and natural aging, no fading, cracking and warping after long-term outdoor use.
03
High Dimensional Stability
Advanced directional pressing process ensures low expansion and contraction rate, maintaining flat board surface without deformation.
04
Mold & Corrosion Resistant
Effectively inhibits mold growth and avoids wood corrosion, extending outdoor service life greatly.
