Compare Blandex (OSB) and plywood for wall and roof sheathing: cost, moisture resistance, durability, ease of use, and environmental impact.
Comparing Blandex and Plywood for Wall and Roof Sheathing Choosing between Blandex and plywood for wall and roof sheathing depends on your budget, climate, and durability needs. Here's a quick breakdown: - Blandex: Cheaper (15–30% less than plywood), made from engineered wood strands, and eco-friendlier due to its use of smaller, faster-growing trees. However, it’s more prone to swelling when exposed to moisture and requires careful weatherproofing during installation. - Plywood: Costs more upfront but resists moisture better and holds its shape even after getting wet. Its layered construction ensures long-term durability, making it a better option for humid or wet climates. It also emits fewer chemicals, improving indoor air quality. Key Takeaway: Blandex works well for dry climates or tight budgets, while plywood is better for humid regions or projects where long-term durability matters.
