In 1924 two Hungarian immigrants, starting out with nothing, established a new company and named it “Zero.” Over the decades that followed, ZERO INTERNATIONAL pioneered countless innovations for achieving maximum performance in door and window sealing systems. In the process, we earned a worldwide reputation for exacting standards in the design and quality of our products. Today, our end users and their designers ask for “ZERO, no substitutes” when they want the best value in products that perform reliably over years of hard use. And our OEM partners turn to ZERO for expertise and superior quality that give them a competitive market edge.

      Experience in this demanding industry proved from the beginning that “one size fits all” does not apply to gasketing. So we look at specialized functionality to design performance-based sealing systems that work right for specific applications to block air, light, water, fire, smoke and sound. Our purpose is always to build the best possible product for its use. Quality remains a constant for ZERO.

     As you scan the pages of our website, you will find that there’s more to ZERO than ever before. We’re a full-line company providing a single source for high-performance hinges, saddles and thresholds, in addition to our integrated, specialized door sealing systems. And we now offer as well a wide variety of door louvers and vision lites through our newest company, Advantage Lites & Louvers.

     We support all of our product lines using extensive in-house production capabilities combined with engineering strength and ingenuity to solve problems creatively. We make our own rubber extrusions through our IND-EX subsidiary in Middlefield, Ohio. Our INTUMET division produces our intumescent material for fire and smoke gasketing, as well as firestopping applications. We even make our own photoluminescent material and signage for compliance with requirements for exit path markings already in effect in New York City, and pending in other parts of the country.

     These unparalleled capabilities afford unique flexibility in responding to customers’ special requirements. We listen to our customers, and we deliver exactly what they need. And we make sure it lasts.
