Heat and conditioned air loss around your doors is costing you more money than you might think. One of the quickest and easiest ways to reduce energy waste is to seal air leaks by using weatherstripping. Weatherstripping will stand temperatures between -40 and 50 degrees Celsius. They can be installed at the threshold, as well as around and at the bottom of garage doors. 4.9m (16ft) ultra-resistant neoprene, rubber and foam garage door bottom weatherstripping. Available in black.
