Garage door weatherstripping is one of the most overlooked yet essential components of your garage door system. This comprehensive guide will help you understand why weatherstripping matters, the different types available, and how to maintain it for optimal performance.
Your garage door is the largest opening in your home, and without proper weatherstripping, it becomes a significant source of energy loss, pest entry, and weather damage. Quality weatherstripping creates a tight seal between your garage door and the frame, providing protection against the elements and improving your home's energy efficiency.
In Central Florida, where we experience everything from intense summer heat to occasional cold snaps and frequent rain, proper weatherstripping is especially important. It helps keep your garage cool in summer and warm in winter, potentially saving you hundreds of dollars annually on energy costs.
Bottom Seal (Astragal): This is the strip that runs along the bottom of your garage door. It's typically made of rubber or vinyl and prevents water, dirt, and pests from entering under the door. U-shaped and T-shaped seals are most common, with T-shaped being more durable.
Side Seals (Jamb Seals): These run vertically along both sides of your garage door frame. They're usually made of vinyl or rubber and help seal gaps between the door and the frame.
Top Seal (Header Seal): Located at the top of the door frame, this seal prevents water and debris from entering above the door. It's particularly important in areas with heavy rain.
Threshold Seal: Unlike the bottom seal which attaches to the door, a threshold seal attaches to the floor. It provides an additional layer of protection and is excellent for garages with uneven floors.
