Papillon Garage Door Bottom Seal Strip – 20ft Grey EPDM Weatherproof Threshold, DIY Friendly

Upgrade your garage with the Papillon Garage Door Bottom Seal Strip. This weatherproof EPDM barrier sits along the threshold to block wind-driven rain, snow, and leaves, helping keep the interior drier, quieter, and more energy-efficient. The grey strip is designed to fit standard doors and can be trimmed to your exact width for a tailored seal.

Durable, Weather-Ready Construction

Crafted from premium EPDM rubber, the seal stands up to temperatures from -40°F to 284°F and resists cracking, drying, or shifting. It helps reduce condensation-related damage and keep metal surfaces from rusting, even in harsh seasonal shifts.

• Blocks water, wind-driven rain, snow, and leaves
• Keeps the garage drier and quieter
• Maintains flexibility through temperature swings and daily vehicle traffic
• Reduces condensation risk and rust formation

Flexible, DIY-Friendly Fit

Length up to 20 feet (6 meters) with a 3-1/2 inch width. It can be cut to fit your door threshold for a precise seal. The installation is designed for quick DIY work—no professional tools or adhesives required. Each package arrives with slightly extra material to accommodate fit variations.

• Cut-to-fit for a custom seal
• No adhesive required; simple DIY install
• Slightly longer than advertised to ensure coverage

Real-World Benefits

Beyond the weather barrier, the seal helps create a cleaner environment: less wind noise, fewer drafts, and a lower risk of moisture intrusion. It supports long-term performance of your garage door and surrounding area by staying flexible through temperature swings and vehicle traffic.

Whether you use it for a single door or multiple bays, Papillon's bottom seal strips offer a straightforward upgrade to your home. Expect improved comfort without sacrificing door movement or reliability.
