Clear comparison of OSB vs plywood for DIY projects: cost, moisture performance, strength, VOCs, and which panel suits each application.
The Ultimate Comparison: OSB vs Plywood for DIY Builders When choosing between OSB and plywood for your DIY project, the decision boils down to cost, performance, and durability. OSB is cheaper, making it a go-to for budget-conscious builders. However, plywood outperforms OSB in handling moisture, maintaining shape, and holding fasteners, making it better for areas prone to dampness. Both materials have their strengths, and the right choice depends on your project’s specific needs. Here’s a quick breakdown: - OSB: 15–30% cheaper, better for large-scale, dry projects. Struggles with water exposure but uses wood efficiently. - Plywood: Costs more but resists moisture better, holds fasteners securely, and emits fewer VOCs, making it ideal for damp or indoor spaces. Quick Comparison | Feature | OSB | Plywood | |---| --- |---| | Cost | 15–30% cheaper | More expensive | | Moisture Handling | Absorbs water, swells edges | Dries faster, minimal swelling | | Durability | Less rigid when wet | S...
