"Insulated Garage vs. Bills? Tested Efficiency Savings!" We were skeptical but intrigued when we unboxed the 3009 Garage Door Insulation Kit. The silver panels looked sleek, and the easy assembly promised fewer headaches. True to word, the adhesive pads stuck effortlessly, and the lightweight design made installation a breeze. Each of the 8 bubble insulation panels covers a decent section, effectively blocking up to 95% of radiant heat. Our garage, once a cozy oven in summer, now feels significantly cooler. While it may seem like an upfront cost, we’ve already noticed a difference in our energy bills—ourselves and the wallet. If you’re looking to balance temperature control and savings, this kit delivers quietly and effectively.
