Owen’s is a well-known brand in the insulation world and the name alone carries some weight, as well as the positive experiences with customer services that reviewers have had. Our second option for garage door insulation is Owen’s corning kit, which comes complete with clips to hold it in place.
Made with fiberglass, this kit comes with an R-8 rating, which is one of the highest available. It is, however, more difficult to set up and is held in place with clips, which means more precision is required when installing your kit. Some customers note that more than a little bit of Gorilla tape is required to get the optimal hold, over using the clips alone- a great tip for those looking to invest!
