How It's Made
The engineered strength of OSB technology ensures a reliable longer length product:
- Rectangular wood strands blended with thermal-set, waterproof adhesives are arranged in cross-directional layers
- The layers are consolidated under extreme pressure
- A stiff, strong and durable OSB panel is created
