CertainTeed 902008 8'4" x 100' Smart Vapor Retarder Barrier, No Size, Clear

Review: producto que alcanzo mis espectativas - Excelente producto que use para forrar todo el techo de mi pared. Es dificl de romper y facil de instalar. un producto que les recomiendo sin dudar, pues me ayudo mucho a forrar el segundo piso(paredes & techo.
Review: Works great and easy install - Used in the northeast as a vapor barrier on the inside of the walls while allowing for moisture to move depending on season. I followed the install instructions on the Certainteed website where they have a 12 page pdf to print out and was very useful. Used with Tuck Tape sheathing tape to tape seams, and around outlet boxes. Used a silicone adhesive per the requirements in the instructions. And used a battery powered staple gun that was very useful in making install easy. It seems very crinkly at first, but after installed one day it feels very flexible/stretchable. I suggest stretching it over the outlets the next day. It covered a 12x20 building interior including the ceiling perfectly. I only had scraps left over. Update: I noticed moisture on the inside of the barrier on the south facing wall. I asked CertainTeed and they quickly replied. After I get the heating installed, this will no longer be an issue. Hot, humid air outside is condensing on the cooler inside barrier. So I will be waiting to install the wallboard until after I get the heat installed. The barrier is doing a great job keeping out drafts and the room warms up nicely with a space heater.
