Intumescent Smoke Seal Strip Tape – Flexible Expanding Fire Door Strips
Pro Chutes offers an Intumescent Smoke Seal Strip Tape designed to expand under heat and seal gaps instantly, blocking fire and smoke. The product uses a 3M adhesive grid that provides strong adhesion, helping the strip stay in place for long-term protection around fire-rated doors and windows.
Installation is described as tool-free: cut, peel, and stick. The graphite and rubber composite material is built for high-temperature environments, maintaining a firm seal under challenging conditions. The tape is intended for fire-rated doors and windows, delivering a professional-grade seal when applied correctly.
Key considerations: ensure clean mounting surfaces for best adhesion, verify door clearances to prevent binding, and plan for edge-to-edge coverage around frame gaps. This option is particularly suitable for retrofit projects where existing gaps need rapid, reliable sealing during fire events.
JELOSTONE 2 Pack – Fire/Smoke Perimeter Gasketing
This JELOSTONE set includes two 20-foot rolls of self-adhesive silicone weather stripping, designed to seal door tops and sides against fire, smoke, air, and sound. The silicone gasketing offers high-temperature resistance, with UL V-0 grade fire resistance for residential and commercial applications.
Each roll provides substantial length for multiple doors, making it a cost-effective retrofit solution. The gasket is rated to operate effectively from -58°F to 450°F, maintaining performance in varied outdoor and indoor environments. It self-extinguishes after flame exposure and reduces the risk of flaming drips.
Considerations include roll length versus door perimeter, color options to match door aesthetics, and surface compatibility with existing door finishes to ensure clean, long-lasting adhesion.
Innconee 2 Rolls Intumescent Smoke Seal Strip Tape
Innconee provides two rolls of intumescent smoke seal strip tape that expand to block fire spread when exposed to high temperatures. The adhesive-backed composite uses graphite rubber material designed to resist heat while delivering reliable adhesion with minimal residue upon removal.
Each roll measures 0.6 inches by 0.08 inches by 9.8 feet, offering flexibility for multiple doors or windows. The product emphasizes long-lasting performance across a wide temperature range, making it suitable for both interior and exterior frames where fire and smoke protection is a priority.
Practical use includes sealing door gaps, window perimeters, and other vulnerable joints where smoke can travel. Ensure proper surface prep and align with door movement to maintain an effective seal over time.
JELOSTONE Commercial Door Bottom Sweep JS-NV307
This heavy-duty door bottom sweep features an aluminum carrier with a vinyl insert for a robust weather seal. It carries a UL 10B/10C fire-resistance rating, adding a protective layer to the bottom of outswing doors and other exterior openings.
Designed for compatibility with various door sizes, it includes slotted holes for easy adjustment and stainless steel fasteners. The product is intended to seal gaps up to one inch, reducing drafts while offering fire-rated protection for high-traffic entrances.
Key considerations include door thickness, floor clearance, and the need for occasional maintenance to ensure the vinyl insert remains effective in sealing against air and smoke intrusion.
JELOSTONE U-Shaped Aluminum Door Bottom Shoes JS-217DV
JELOSTONE JS-217DV U-shaped aluminum door bottom shoes provide durable weather-stripping with a fire-rated design. The assembly includes a vinyl insert that seals gaps at the bottom of exterior doors, combining structural robustness with effective air and smoke sealing.
With UL 10B/10C fire resistance and adjustable features via slotted holes, these bottom shoes are commonly used on outswing doors. They offer compatibility with various door configurations and provide reliable gap sealing up to about half an inch.
Installation notes focus on selecting the correct door width and ensuring the bottom shoe aligns with the door sweep for a consistent seal when the door closes.
Buying Guide: Key Purchase Considerations And Comparisons
- Fire resistance rating: Look for UL or equivalent fire ratings (e.g., UL 10B/10C) on door bottom components and intumescent tapes to confirm they meet building code expectations for your application.
- Material and expansion: Intumescent tapes rely on heat-induced expansion. Graphite/rubber composites and silicone gasketing provide durability and high-temperature performance but differ in flexibility and adhesion. Match material to door material and climate.
- Adhesive strength and residue: Strong 3M-backed adhesives help ensure long-term adhesion. Some products claim residue-free removal; verify surface compatibility to avoid damage on painted or stained doors.
- Door type compatibility: Exterior doors, interior doors, and windows have different sealing needs. Bottom sweeps and U-shaped shoes suit door perimeters, while perimeter gasketing better fits door frames and window openings.
- Installation practicality: Tool-free or minimal-setup products are ideal for quick retrofits. Verify surface prep requirements (clean, dry, and smooth) before installation.
- Gasket thickness and gap coverage: Measure the gap width and target sealing range (e.g., up to 1/2 inch or 1 inch) to choose components that provide sufficient contact without impeding door operation.
- Durability under weather conditions: For exterior applications, select materials resistant to UV, ozone, extreme temperatures, and moisture to minimize deterioration over time.
- Maintenance and replacement: Consider replacement cycles, ease of reapplication, and availability of compatible accessories for future upgrades or repairs.
In summary, selecting the right combination of intumescent seal tape, perimeter gasketing, and door bottom components can substantially improve fire resistance and reduce smoke intrusion. Prioritize products with proven fire ratings, strong adhesion, and compatibility with your door type and climate to achieve reliable protection over the long term.
