Innconee Adhesive Fire/Smoke Gasketing — 2 Rolls (Black)
Innconee’s adhesive silicone smoke seal is designed for doors and windows in indoor, outdoor, and commercial settings. Each package provides two long rolls that can be cut to fit various gaps. The 0.5″ width and 0.25″ height allow a snug seal within a wide range of door seams, with effective gap sealing up to 1/16 inch. Made from high-temperature resistant silicone, it maintains flexibility between -58°F and 450°F, reducing closing force while resisting deformation under heat.
Innconee Intumescent Smoke Seal Strip Tape — 2 Rolls
These intumescent smoke seal strips are adhesive-backed and expandable under heat to block fire spread. Each 9.8-foot roll is slim enough to fit narrow door and window slots, with a compact 0.6″ width and 0.08″ thickness. The graphite rubber composite and mesh adhesive offer strong adhesion with clean removal, leaving no residue while delivering rapid expansion to seal gaps when exposed to high temperatures.
Pro Chutes Intumescent Tape — 9 ft
Pro Chutes offers a flexible intumescent strip that expands with heat, forming a tight seal to block smoke and flames. Its 3M-backed adhesive ensures strong initial bonding with minimal residue upon removal. The product emphasizes easy installation—cut, peel, and stick—delivering a reliable, professional fit for fire-rated windows and steel doors while maintaining a durable seal under extreme heat.
Innconee Adhesive Backed Smoke Seal (Black Perimeter)
This adhesive-backed perimeter seal from Innconee is designed for tight frames, offering 0.37″ W x 0.19″ H x 20′ L coverage. Its silicone composition provides high-temperature resilience and low closing force, with deformation resistance that remains stable under sun, ozone, and UV exposure. The product ships in two long rolls, making it practical for larger projects or sharing with others.
Smoker Chef XXL Grill Gasket — 2-Pack
The Smoker Chef smoker gasket is designed for high-temperature grilling applications, offering a 20 ft total length across three 10 ft rolls. It uses a high-temperature, fire-resistant material to minimize smoke leakage and help maintain stable cooking temperatures inside smokers and BBQ grills. The gasket is self-adhesive for easy application across a range of grill lids and frames.
Buying Guide
Key factors to consider when choosing fire and smoke seals include material type, temperature rating, application surface, and ease of installation. Below are perspectives to help you decide what to prioritize:
- Material and temperature tolerance: Silicone gasketing offers high heat resistance and flexibility, suitable for doors and windows exposed to sun and heat. Intumescent strips expand under heat to seal larger gaps and block fire spread.
- Adhesive backing and installation: Self-adhesive options save time and reduce installation mess. Verify adhesive strength and residue upon removal, especially for metal or painted surfaces.
- Gap size and profile: Measure door/frame gaps to select a strip with an appropriate width and thickness. Narrow frames may benefit from slimmer profiles, while wider gaps may require thicker gaskets or multiple layers.
- Durability and exposure: Consider UV, ozone, and weathering resistance if the seal will be exposed to outdoor elements. Self-extinguishing and flame-retardant properties are important for safety-critical applications.
- Maintenance and replacement: Replacing worn gaskets is generally straightforward. Look for products with long service life and easy removal without damaging the door or frame.
- Use case variations: For kitchens, workshops, and garages, prioritize high-heat or smoke-resistance. For residential exterior doors, ensure the seal maintains performance under seasonal temperature changes.
- Combined solutions: In some setups, combining an adhesive silicone gasket with intumescent strips can provide both immediate sealing and fire-growth protection along different door edges.
