Many companies today use steel sheets cut to the length that’s required for the door; and they use steel end caps to close the ends. This causes something called thermal bridging, which is not what you want in a garage door. The thermal bridging means that the metal is going to transfer the heat into or out of the garage.
Using wood end blocks is a much better option. The benefit of using the wood blocks is simple. Wood does not transfer heat. Instead, it causes a thermal break, which makes sure there is no heat lost; in the winter, and that the heat doesn’t get into the garage in the summer. If the weatherstripping on the door is not doing their job; it is going to harden and become inflexible when the temperatures start to drop. This will not provide you with the protection you need.
