  • During sound attenuation testing of the S773 adhesive perimeter seal in conjunction with Pemko automatic door bottom (411_PKL) and Pemko acoustic corner pad (ACP112), the door assembly achieved a 98 percent efficiency rating.
  • Available in 17, 18, 20, 21 and 25 ft. coils.
  • Category H - Gasketing - Smoke and draft control for positive pressure openings. Recommended products are PK33, PK55, S44, S88 and S773.
  • Category H gaskets for use with listed steel frames and/or classified steel covered composite, hollow metal doors rated up to and including 3 hours; wood and plastic covered composite doors rated up to and including 1-1/2 hours; and wood core doors rated for 20 minutes without hose stream. When applied to the door and frame assembly in accordance with the manufacturers installation instruction, the assembly will comply with UBC 7-2 (1997) part II.
  • Category J - Doors - gasketing that has been tested on a positive pressure fire door and frame but is not required for the door to obtain its fire door rating. Category J gasketing does not negatively affect the rating on a positive pressure door.
  • Category J gaskets for use with listed steel frames and/or classified steel covered composite, hollow metal doors rated up to and including 3 hours; wood and plastic covered composite doors rated up to and including 1-1/2 hours; and wood core doors rated for 20 minutes.
  • Category G - Edge-Sealing Systems - systems that are surface applied to frames or doors and required for Category B doors. S773 meets Category G requirements for 3’ x 8’ listed wood core fire doors installed in steel door frames, rated 20 minutes.
  • Storage and shelf life: All adhesive gaskets have a limited shelf life. This product must be used within 6 months of purchase and must be stored between 50 degrees (F) and 100 degrees (F). For further notes/details, please see Adhesive Gasketing section.

To comply with NFPA 80 standards, several key clearance requirements must be observed:

1. Door Clearances: Ensure that the clearance between the bottom of the fire door and the floor or threshold meets specific measurements. Generally, this gap should not exceed 3/4 inch to maintain effective fire resistance.
2. Frame and Hardware Clearances: The space between the door and its frame or the hardware (such as hinges) should be kept minimal. Typically, this means maintaining a clearance of no more than 1/8 inch at the top and vertical edges of the door.
3. Expansion Clearance: Allow for expansion of door materials during a fire, which can affect clearances. This means accounting for potential changes in the dimensions of the door and frame due to heat.
4. Smoke and Fire Gaskets: Use appropriate smoke and fire gaskets to seal gaps around the door and enhance its ability to block smoke and flames.

By adhering to these guidelines, you ensure that fire doors function optimally in an emergency, helping to contain fire and smoke while providing safe egress. Always refer to the latest NFPA 80 standards for any updates or specific requirements for your installations.

• Triple-fin gasketing design effectively blocks light and sound from infiltrating a room. This innovative design utilizes three layers of fins, each acting as a barrier to disrupt and absorb light and sound waves. By creating multiple points of contact, the gasket ensures that both light and sound are significantly diminished before they reach the interior.

The strategic arrangement of fins works much like a series of interlocking shields, with each layer enhancing the overall effectiveness. This makes it ideal for environments needing privacy and tranquility, such as recording studios, conference rooms, or home theaters.

Furthermore, the materials used in the triple-fin design are engineered for durability and performance, providing a long-lasting solution that is resistant to wear and environmental changes. Compared to single or double-fin designs, the triple-fin configuration offers superior performance, prioritizing both functionality and comfort in one seamless package.

When looking for a range of adhesive-backed gasketing and edge sealing systems, you'll find several innovative options available in the market. Here are some popular types:

1. Silicone Gasketing: Perfect for those seeking flexibility and durability, silicone gasketing offers excellent resistance to extreme temperatures, making it an ideal choice for both smoke and fire sealing applications.
2. Rubber Gasketing: This type features elastomeric properties, providing a tight seal that's great for soundproofing and weatherproofing, in addition to smoke protection.
3. Intumescent Edge Sealing: Specifically designed for fire-rated doors, these seals expand when exposed to heat, effectively blocking the passage of smoke and fire through door gaps.
4. Triple-Fin Gasketing: Known for its superior sealing capabilities, this option incorporates three fins that enhance protection against smoke, drafts, and sound.
5. Vinyl Magnetic Seals: These innovative seals incorporate magnetic properties, ensuring a snug fit for metallic surfaces which is crucial for maintaining a seal over time.

These adhesive solutions cater to various needs, from fire safety to environmental control, and are crafted from materials like silicone and rubber, offering something for every requirement.

Effortless Installation of Adhesive-Backed Material on Door Frames

Installing adhesive-backed material on door frames is a straightforward process, making it accessible for both DIY enthusiasts and professionals. Here's how easy it can be:

• Preparation is Key: Before application, ensure the door frame is clean and dry. Remove any dust, grease, or old adhesive residues to maximize the material's effectiveness.
• Peel and Stick Convenience: With a pressure-sensitive adhesive, simply peel away the backing and firmly press the material onto the door frame. This eliminates the need for extra tools like nails or screws, streamlining the installation.
• Versatility in Application: Whether you're using a product from 3M, Gorilla, or another reputable brand, these adhesive materials are designed to conform to various door frame surfaces for a snug fit.
• Time-Saving Process: Depending on the size of the door frame, the entire installation can be completed in minutes, significantly reducing labor time compared to other methods.

By following these steps, you can ensure a smooth and durable installation of adhesive-backed materials on door frames without hassle.
