Advanced Protection Where It Matters
WinSure® Wood Treatment is a factory-applied preservative process that protects wood components from moisture, fungal decay, termites, and wood-destroying insects. It helps preserve the structural integrity and natural beauty of your Windsor windows and doors for years to come.
Factory-Applied Precision
Applied under controlled manufacturing conditions, WinSure provides consistent protection throughout the wood components—including areas that are difficult to treat on-site. The result is reliable performance without affecting the wood's appearance.
Built for Ontario's Climate
From humid summers to freezing winters, Ontario's climate demands durable building materials. WinSure helps protect wood windows and doors from the effects of moisture and seasonal weather, providing long-term confidence for homeowners and builders.
