incredible product Great for all kinds of projects
Would RecommendGreat product very versatile. not UV stable. don't use in direct sunlight. DONT use the Reflectix tape. it falls off. (yes. it was cleaned and applied per instructions) find a different tape for the seams. (3M tape works well) the barrier itself is a phenomenal product a lot of uses!!!
