Garage Door Weather and Bottom Seals

Garage door seals are also known as weatherstripping and astragal. Seals are found around all four edges of the garage door. The purpose of a weather seal is to keep insects and critters out of the garage while also keeping moisture and cold air from seeping through the cracks around the garage door. By weatherproofing your garage door, you can save on your energy bill and stay warmer through the winter.

On the sides and top of the garage door, PVC Stop Molding is installed to the wood trim. When the garage door is closed, the sections of the door are intended to be flush against the frame of the garage. This is not, however, usually the case. When you install PVC Stop Molding, the flap of this type of seal will press against the outside of the garage door, closing the gap between the door and the garage frame. Another type of seal is a Reverse Angle Jamb Seal.
