Product Overview

  • Guards against moisture
  • For use as vapor retarder
  • 100 in. x 50 ft. Air Barrier with Smart Vapor Retarder
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.
  • Unlike traditional vapor retarders, MemBrain helps prevent mold by sensing and adapting 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
  • 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
  • Unique, patented product
  • Roll is 100 in. tall and 50 ft. long
  • The right insulation can save on energy and heating and cooling bills. Check out our Buying Guide for helpful tips.

Questions & Answers

What tape should be used on the seams where 2 pieces of membrain meet?

What tape should be used on the seams where 2 pieces of membrain meet?
Asked by: gp
Use SIGA or Pro Clima tapes. you need to tape ALL seams. Tape is too weak and not vapor open and will not last. This product can be used in high performance or Passive House construction but it must be taped well with the proper product.

I am installing unfaced insulation between the ceiling joists in my basement to help insulate and sound proof between the basement and first floor. Would this product be appropriate to install in this situation?
Asked by: BB
I would think this would work since it’s breathable. I did the same thing a few years ago in my basement with unfaced insulation before this product existed and I used Breathable House Wrap like tyvec.

how does it attach to metal studs?

how does it attach to metal studs?
Asked by: Chris
Normally the vapor retarder is stapled to wood studs but if you are using metal studs then I would spray the edge of the metal stub with 3M adhesive 77, let it tack up then stick the air barrier to it. The adhesive is in the paint department in a spray can at Home Depot stores.

Is this product plastic membrane or a foil ?

Is this product plastic membrane or a foil ?
Asked by: CuriousGeorge
This is a plastic material. It feels a bit like the "crinkly" type of cellophane, such as used in windowed envelopes.
