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. ## Features - Model 902008 is for 8 foot tall walls and is 100 feet long - Unlike traditional vapor retarder, membrain senses and adapts permeance to varying humidity throughout the year to keep the wall cavity dry - For use with un-faced insulation as a vapor retarder in climate zones where one is required - Prevents moisture vapor from entering the wall cavity in the winter and allows any moisture buildup to escape the wall cavity in the summer - Installs like poly with an extra level of moisture protection ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01MS4O729 | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #76,003 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #9 in Scaffolding Equipment | | Color | Clear | | Customer Reviews | 4.4 4.4 out of 5 stars (43) | | Date First Available | January 6, 2017 | | Included Components | One roll of MemBrain - 8' x 100' | | Item Package Quantity | 1 | | Item Weight | 11 pounds | | Item model number | 902008 | | Manufacturer | CertainTeed | | Material | Plastic | | Part Number | 902008 | | Product Dimensions | 5 x 5 x 12.5 inches | | Size | No Size | | Usage | Inside | | Warranty Description | Warranty | ## Images ![CertainTeed 902008 8'4" x 100' Smart Vapor Retarder Barrier, No Size, Clear - Image 1](https://m.media-amazon.com/images/I/61S8XeKD1sL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***A on August 27, 2025* Excelente producto que use para forrar todo el techo de mi pared.
