Super Low Perm Ratings…Barrier Bac meets or exceeds all ASTM requirements for vaporbarrier and vapor retarder.Barrier <.1 perms Retarder <1.0 permsSome manufacturers make a big deal of super low perm ratings.Studies show that at .1 perms, a material has a moisture blockingratio of 99.96%.Think about it, that’s 4 one hundredths of one percent. We reallyneed to be looking at seams, tape, and overall installation.
Why Tape is ImportantASTM 1745-09 mandates a provider ofvapor barrier MUST: Detail seam, lap, penetration procedures Detail seam, lap, penetration materials PROVIDE seaming medium (by specification) that meets or exceeds the vapor barrier tech properties. Long story short – it’s only as strong as it’s weakest link

Where its made matters Barrier Bac is made in the USA. It is 100% domestic. From the resin to the finished product, it is born and raised in Lolita, TX. The Barrier Bac line is made by Inteplast, an ISO 9001:2008 manufacturer. This is the highest international quality standard available and Inteplast is the largest plastics extruder / resin producer in the world.
How its made matters Barrier Bac is a ribbed, cross laminated, extruded film. 7 cross laminations make for increased puncture resistance 7 cross laminations do not allow punctures to propagate Ribbed surface reduces personnel slippage Ribbed surface provide mechanical bond to concrete ( up to 4lbs / sqin peel adhesion ) Ribbed surface provides and overlap interlock for stress free seaming.
Barrier Bac VB 250 11 mil high performance under slab vapor barrier developed for the construction industry to retard moisture migration through concrete slab. It may also be used to control radon, methane, sulphates and many other soil contaminants. VB-250 exceeds Class A, B, C of ASTM E1745-09 specifications. Applications It is the most cost efficient solution to vapor moisture migration and most reliable replacement of visqueen sheet. Availability VB-250 is available in standard roll, green color, and size 12.75 ft × 200 ft. However, other colors and sizes are available upon request.
Barrier Bac VB 350 16 mil high performance under slab vapor barrier developed for the construction industry to retard moisture migration through concrete slab. It may also be used to control radon, methane, sulphates and many other soil contaminants. VB-350 exceeds Class A, B, C of ASTM E1745 specifications. Applications It is used in projects of high requirements in water vapor permeance, tensile strength and puncture resistance. Availability VB-350 is available in standard roll, green color, and size 12.75 ft × 150 ft. However, other colors and sizes are available upon request.
Barrier Bac VBC 350 31 mil Composite vapor barrier with non-woven geo-textile fabric lamination. With the extra lamination, VBC-350 provides a mechanical bond with concrete when placed with geo-textile facing concrete pour (Peel Adhesion to Concrete up to 8 lbs/in). This bond greatly improves slab protection from moisture migration by maintaining tight contact with the slab, especially under expansive soil conditions where foundations may swell and contract. Typical use includes projects with expansive soil conditions, void formed slab and high water table.
Barrier Bac Summary:What no other materials can provide Barrier Bac is manufactured at our ISO certified plant Barrier Bac manufactures its own resins Barrier Bac manufactures its own products Barrier Bac manufactures and ships from Texas Barrier Bac can / will provide a certificate of origin for LEED credits and for federal projects (Made in USA) Barrier Bac has peel adhesion to concrete Barrier Bas has a protective ribbed layer Barrier Bac ribs provide a mechanical seal at overlaps Barrier Bas has a non-slip working surface Barrier Bac manufactures a virgin polyolefin tape that will not degrade
