Door Gasketing and Seals

For nearly a century, National Guard Products has been a trusted name in the commercial door product industry. Whether it’s sealing, securing, sliding, or visibility, NGP has consistently delivered top-tier solutions. Founded in 1935 with a staunch commitment to customer service, NGP has grown to become a leading manufacturer, known for its quality, innovation, and unparalleled service.

Gapguard Fire Door Solutions

National Guard Products developed the Gapguard series to address excessive clearance issues on fire-rated door assemblies. These components mount directly to the door bottom or jambs to seal gaps that exceed NFPA 80 standards. The system allows facility managers to bring existing doors back into compliance without the cost of total replacement. The line includes fire-rated sweeps, shoes, and intumescent seals that maintain ratings for up to 90 minutes.

Lite Kits and Louvers

NGP manufacturers a complete line of vision frames and ventilation louvers for commercial openings. The inventory includes low-profile, self-attaching lite kits compatible with various thicknesses of fire-rated glass. Louvers provide essential airflow between rooms while maintaining security and blocking light transmission. These components are available in multiple architectural finishes to match existing hardware and specific project requirements.

James Eck

Customer

As many know, doors can be one of the most difficult and frustrating trades to work on in a major project. There are many things that can go wrong with doors and their procurement. Builder’s Door is on top of it all. On a recent project, builder’s door used quick and flexible thinking to provide the products we needed of them in a manner that fit our schedule. Unlike most subcontractors, they did not passively present problems for us to solve, but explained the problem, proposed solutions, and told us the pros and cons to those solutions. They acted like a partner, not just a vendor.
