InternationalCONFUSED ABOUT VAPOR BARRIERS?
One of the most difficult decisions you can be faced with is trying to compare products as “true” alternatives to each other. Thankfully, testing procedures allow you the ability to compare physical properties side by side.
W. R. MEADOWS, the originator of under-slab vapor barrier protection, is concerned that confusing information is being provided to you, the specifier. If you design it, you own it, so you need to trust the companies you’re dealing with.
FACT:
There are two vapor retarder specifications with very different performance requirements.
They are ASTM 1745 Class A, B, and C for plastic film vapor retarders and the more stringent (lower perm rating) ASTM 1993 specification for critical area use.
Be wary of download specifications that pit an ASTM 1745 material against a material that meets the more stringent ASTM 1993 specification.
The ASTM 1993 material is 150 times more effective at stopping water vapor. Confusing? You decide – it’s your building … forever.
