About ZERO

Industry Leadership Since 1924

In 1924 two Hungarian immigrants, starting out with nothing, established a company and named it "Zero." Over the decades ZERO INTERNATIONAL has pioneered countless innovations for maximizing performance in door and window sealing systems. Today we are known worldwide for design, quality and creative problem-solving that set the standard for our industry. End users and their designers ask for "ZERO, no substitutes" when they want 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 edge.

As you browse our website, you will find that there's more to ZERO than ever. We're a full-line company providing a single source for high-performance hinges, saddles, thresholds and specialty products, in addition to our integrated, specialized door sealing systems. And we offer a wide variety of door louvers and vision lites through Advantage Lites & Louvers, a ZERO company located in Wallace, North Carolina.

Innovation

Our experience in engineering solutions for demanding door and hardware applications has proved that "one size fits all" does not apply to gasketing. So we look at specialized functionality to design performance-based 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, keeping in mind at all times our life-safety responsibilities.

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

These unequaled capabilities afford unique flexibility in responding to customers' special requirements. They have also produced a distinguished history of "firsts", including:

  • the first integrated door sealing systems
  • the first door gasketing suitable for soundproofing
  • first in our field to manufacture intumescent products
  • the first intumescent material designed specifically for doors
  • the first fire and smoke control systems for positive-pressure ratings
  • first in our field to manufacture photoluminescent products

Quality

Quality remains a constant for ZERO. Ongoing commitment to the highest standards for performance and durability has made our name synonymous with QUALITY in our industry. That's why gasketing specifications for projects where quality matters stipulate "ZERO, no substitutes." We are also recognized for providing expert technical support for both the specification and application of our products.
