Our new proprietary technology has allowed W. R. MEADOWS to formulate a vapor barrier to significantly exceed the requirements of ASTM E 1745 (0.1 perms), as well as the recommendation of ACI 302.2R. ACI 302.2R states that a vapor barrier is to be installed with a perm of less than 0.01 in areas where the requirements of ASTM E1745 are not sufficient to protect the floor. PERMINATOR exceeds this ACI requirement by 37%, while at the same time providing the specifier peace of mind that its superior puncture resistance will protect this low perm rating by resisting punctures on the jobsite.
With our new PERMINATOR 15 product technology, W. R. MEADOWS is now able to provide the entire building team with the lowest vapor permeance, while at the same time providing a puncture resistance that is over 45% better than required by the ASTM E1745 standard.
