A specific type of weatherstripping designed for garage doors, this seal features a rounded, bulb-shaped profile. This specialized design is intended to create a tight barrier between the bottom edge of the garage door and the floor. For example, when properly installed, this profile conforms to minor irregularities in the concrete, preventing ingress of water, debris, and pests.
The primary importance of this sealing solution lies in its ability to protect the garage interior from external elements. This protection translates to energy savings by reducing drafts and maintaining a more consistent temperature. Furthermore, it prevents damage to stored items from moisture and insects, contributing to the long-term preservation of the garages contents. Historically, simpler, less effective seals were used, leading to increased problems related to weather and pest intrusion, highlighting the value of the improved bulb design.
