MDO

Tough, smooth, and weather-resistant, MDO (Medium Density Overlay) is a premium-grade plywood designed for exterior and high-moisture applications where durability and a clean finish matter. We offer top-quality MDO panels ideal for outdoor signage, soffits, fascia, cabinetry, concrete forms, and painted projects that require strength and stability. MDO is constructed with a core of industrial-grade plywood and a resin-impregnated paper overlay that provides a smooth, paint-ready surface. It resists warping, cracking, and delamination—making it perfect for Canadian weather conditions and long-lasting performance in tough environments. As a proudly Canadian company, Windsor Plywood specializes in hard-to-find building materials and offers expert, one-on-one service. Whether you're building durable exterior features or creating a smooth, professional finish for interior work, MDO delivers both rugged reliability and a superior surface.
