Product Overview

For extra protection against moisture, the MemBrain Continuous Air Barrier and Smart Vapor Retarder is your weapon of choice. It lets wall cavities dry out, to help prevent mold. In summer, when humidity is high, it increases permeability so that moisture can escape, as air tightness is maintained. In winter, when humidity is low, it continues to block moisture. Use MemBrain with un-faced insulation in place of kraft faced insulation or polyethylene. Not all climate zones require vapor retarders.
  • 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
  • Allows any moisture buildup to escape the wall cavity in the summer
  • Installs like poly with an extra level of moisture protection
  • Continuous air barrier and smart vapor retarder

can an 18ga pneumatic narrow crown stapler and staples be used for installation? if so, is there a specific type?

Asked by AbeV December 15, 2018

Answers

A regular T50 type stapler works well. We used an inexpensive pneumatic stapler with 1/2" T50 staples - it speeds up installation and avoids hand & wrist fatigue.

What is the mil. of the product? Why is this better that using an ordinary plastic type wrap?

Asked by Steve May 26, 2017
1
Answer

Dear Steve: Thank you for your question! MemBrain Continuous Air Barrier & Smart Vapor Retarder is a Class A Fire Rated 2-mil thick film of polyamide (nylon). One of the main reasons why the Membrain Continuous Air Barrier & Smart Vapor Retarder is superior to other products is because of the advanced technology that allows the product to sense and adapt premeance to varying humidity in order to keep the cavity dry. Homes using traditional polyethylene vapor retarders may actually trap moisture in the cavity during the summer months- raising the risk of costly moisture and mold issues, structural damage, health consequences and liability. This patented, revolutionary solution can provide a continuous air barrier along with advanced moisture management in a single product, helping achieve Complete Comfort. If you would like more information on CertainTeed’s MemBrain product, please refer to the following page of CertainTeed’s website: https://www.certainteed.com/building-insulation/products/membrain/ If you have any further inquiries please call one of the members of CertainTeed’s Sales Support Group at 800-233-8990.

Where to install this product?

Asked by Yeni December 14, 2019
1
Answer

This is a vapor shield typically used in basements to cover the insulation instead of drywall. We used it in a county that required it specifically as the only alternative to drywall (which was a significantly more expensive finish).

Is this product recommended to cover existing fiber glass insulation located in the rim joists? ...

Asked by Carlos November 8, 2019
1
Answer

Yes this product is a good vapor retarder and will help keep drafts out. According to the manufacture if it gets damp the material has special pores that adapt to the moisture and can open up more to dry out. This helps to keep mold from forming. Unless you have a basement that stays wet. Then you would need to address that issue first. Just be sure you do not have any mold on or behind the existing insulation. Hope this helps, ED~

Asked by Ry October 16, 2019

Answer

Yes, Membrain would be a good choice here. It's much better than poly in that it helps prevent moisture from building up inside the wall. This is important because fiberglass loses R value when it gets damp.

This is a great product. We installed it easily. It’s folded to make it possible to install by yourself, but I suggest 2 people. It is a bit more fragile than plastic, but plastic is old fashioned, the membrane is what you pay for.

While it looks like ordinary sheet plastic at first, it is clear that there is more to it. The stud line markings at the top were very helpful and the fire rating says for sure it is not ordinary.

unfolds easily if you read the directions. easy to install, but you really need two people. staples well, but will rip easily if you're not careful. use a sharp razor knife to cut.
