Review on Frost King 1 Black by Ruby Thomas

This black insulation strip worked great for sealing gaps around my air conditioner improving energy efficiency and keeping my home cooler during those hot summer days .As a result of my tests, I determined that it reduced air leakage and improved overall performance. The adhesive backing was strong and easy to apply around the edges of MY AC unit. The only downside was that it was a bit difficult to cut to size. Overall, I am pleased with this purchase and would recommend it to anyone looking to cool down their home and save on energy costs. Home and Kitchen enthusiasts should definitely give it a try!
