Innconee 2 Pcs Adhesive Fire/Smoke Gasketing

The Innconee gasket is a flexible silicone rubber seal designed for door and window use. Each package includes two rolls, allowing you to cut pieces to fit specific gaps. The gasket measures 0.5 inches wide by 0.25 inches high and comes in a 20-foot length, offering ample material for multiple doors or seasonal projects. The drop-shaped profile helps seal a range of door seams, with effective closures up to a 1/16 inch gap. It is rated for high-temperature environments, maintaining flexibility from -58 to 450 degrees Fahrenheit and reducing closing force while resisting deformation over time.

Key considerations

• Adhesive-backed installation simplifies mounting on metal or wood frames.
• Long rolls reduce the need for frequent replacements.
• High-temperature tolerance supports durability in busy doors near kitchens or furnaces.

Pemko – S88D18 SiliconSeal Adhesive-Backed Gasketing

Pemko’s SiliconSeal is a high-temperature, adhesive-backed gasket designed for fire and smoke sealing. Exposed to temperatures from -58°F to 450°F, it compresses to seal up to a 1/16 inch gap after initiating compression at about 1/4 inch. The material is self-extinguishing and non-toxic, with resilience to sunlight and ozone exposure. This gasket provides a reliable, uniform seal along door frames and thresholds, reducing air leakage and smoke passage in both residential and commercial settings.

Performance notes

• Adhesive backing allows fast, clean installation along door frames.
• High temperature range supports demanding environments.
• Non-toxic and UV-resistant properties enhance safety and longevity.

Innconee 4 Pcs Adhesive Fire/Smoke Gasketing

This option extends the two-pack concept into a four-pack, offering quadruple coverage for multiple doors or extra material for future needs. The same 0.5″ by 0.25″ by 20′ profile ensures compatibility with a broad range of door seams, enabling sealing up to a 1/16 inch gap. The gasket is constructed from high-temperature resistant silicone, prioritizing flexibility and stable performance even after extended exposure to heat and repeated door cycles. Adhesive backing aids straightforward installation on various substrates.

Practical deployment

• High roll count supports larger projects or multi-door installations.
• Drop-shaped gasket design helps achieve snug fits in diverse door configurations.
• Reliable compression and deformation resistance across temps.

Pemko S88W20 Adhesive Fire/Smoke Siliconseal Gasketing

Pemko’s S88W20 offers an adhesive-backed silicone gasket in a white finish, designed for fire and smoke door gasketing. This 20-foot roll provides ample material for sealing gaps along door frames and thresholds. The silicone formulation supports resilient performance under heat, while the adhesive backing facilitates clean application on various door materials. The product is positioned for spaces where a light, unobtrusive seal is preferred, yet still capable of contributing to smoke containment and energy efficiency.

Key takeaways

• White finish blends with light-colored door frames while remaining functional.
• 20 linear feet per roll supports sizable sealing tasks.
• Adhesive-backed silicone offers straightforward installation.

Buying Guide: How to choose the right smoke gasket for doors

Selecting the best gasket requires balancing material quality, fit, and installation needs. Consider these factors to align a product with your doors and space:

• Material and temperature tolerance: Silicone gaskets provide heat resistance and long-term flexibility, often performing from -58°F to 450°F or higher. For kitchens, garages, or exterior doors, this matters more.
• Adhesive vs. mechanical mounting: Adhesive-backed gaskets simplify installation but may require surface prep for best adhesion. Non-adhesive or clip-on options offer reusability and easier removal.
• Profile and fit: A 0.5″ x 0.25″ cross-section with a drop-shaped profile tends to seal varied door gaps effectively. Check the maximum seal gap (often up to 1/16″) to ensure compatibility with your door clearance.
• Roll length and quantity: Long rolls reduce the need for multiple purchases and allow for multiple doors or future replacements. Assess the total feet per package relative to your project scope.
• Finish and aesthetics: White or black finishes suit different door styles. While appearance doesn’t affect performance, it may influence your preference in visible installations.
• Durability and weather exposure: Outdoor or garage doors benefit from materials with UV resistance and ozone durability to maintain sealing performance over time.
• Fire/smoke ratings: For safety-critical installations, verify if the gasket is designed for fire/smoke containment and complies with relevant building codes or standards.

To compare options, map product features to your door type (interior, exterior, metal, wood, or composite) and your climate. A higher temperature tolerance, robust adhesive bonding, and an adequate seal gap are indicators of a gasket that will perform reliably under everyday use and harsh conditions alike.
