Vapor Retarders and Vapor Barriers
What is the difference between a vapor barrier and a vapor retarder?
A vapor barrier stops more vapor transmission than a vapor retarder. A vapor barrier is usually defined as a layer with a permeance rating of 0.1 perm or less, while a vapor retarder is usually defined as a layer with permeance greater than 0.1 perm but less than or equal to 1 perm. Synergy’s North American partner, W.R Meadows, beats the lowest in the industry with 0.002 perms.
PREMOULDED MEMBRANE® VAPOR SEAL with PLASMATIC® CORE (PMPC)
Vapor proofing for slab on grade regulates the air inside buildings creating energy efficiencies. It prevents flooring problems associated with vapor build up such as delamination, debonding, bubbling etc. PMPC prevents moisture, vapor and radon gas from entering into the structure.
PMPC has been used on several international projects including Atlantis Hotel, Dubai and Mshereib project in Qatar. Not only does it meet with the highest standards in the industry, it is also easy to install and eliminates the use of protection screeds or blinding.
Key features:
- Most suited for slab on grade – horizontal applications
- Excellent tensile strength and puncture resistance
- 0.002 perms – lowest in the industry meeting most stringent ASTM E 1993-98
- Easy to install
- Blinding or protection screeds not required
- Better performance than conventional membranes
- Supports energy efficiency – contributes to LEED credits
