I installed these in my business. The only downside is you have to be patient with the adhesive you use. These are made of plant fiber and not synthetic materials so they absorb most adhesives. Foam and caulk adhesives take a some time to dry in place. I preferred the contact cement, but it still takes about 20 to 30 minutes to become tacky and settle into place. Overall they are great. Watch you tube videos for installation. They are very helpful.
