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

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.

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.

Thanks

Great product! We thought it would be thinner and rip easily but it was thick and sturdy. It was fairly easy to install. Completely satisfied with our purchase. We installed this in our basement where we thought it would be very useful in terms of its advertised properties.

Product not as described buyer beware
