Master the elements with Durabuilt's 5 Seal Defense System. Exclusively featured in Durabuilt's redesigned Hybrid Collection, the Hybridex 920 and Tri-Bridex 960, are the industry's first and only window series to feature five seals over the standard three. This innovative design is proven to deliver the functionality of an operating casement, with the energy efficiency and performance of a fixed window. Like a shield of armour, the 5 Seal Defense System prevents air and water leakage in areas traditionally vulnerable to Mother Nature’s wrath.
