🪵 **Description**
OSB (Oriented Strand Board) is stronger and tougher than most softwood plywood thanks to thousands of real wood strands in each board. It’s the go-to choice for builders seeking quality and affordability in one structural panel.
🏗️ **Key Features**
- Structural use: **Yes**
- Interior & Exterior use: **Yes** (seal all edges and faces externally)
- Moisture resistant: **Yes**
- Fire retardant: **No**
- Applications:
Timber frame housing, flat/pitched roofing, sheathing for walls/roofs/floors, caravans, sheds, stables, panelling
🌍 **Eco-Friendly**
Made from fast-growing renewable wood species — a great alternative to traditional plywood with a reduced environmental footprint.
🔍 Important distinction: Moisture-resistant doesn’t mean waterproof. OSB can handle rain and humidity to a degree, but prolonged exposure or standing water can still cause swelling or degradation over time.
