Frequently Asked Questions
What is WR Meadows PERMINATOR EVOH TAPE used for?
It seals overlaps, joints and penetrations in PERMINATOR EVOH underslab gas vapor barrier. WR Meadows says it should be used in all PERMINATOR EVOH installations so critical seams do not let harmful gases escape.
How much PERMINATOR EVOH TAPE do I need?
One roll of tape adheres approximately one roll of PERMINATOR EVOH, so one carton of 12 rolls covers about 12 rolls of membrane. Extra detailing at penetrations will add to that.
How is the tape installed on PERMINATOR EVOH seams?
Overlap all side and end seams of the membrane 12 inches. Place PERMINATOR BUTYL TAPE underneath the overlap to hold it in place, then tape the seam with 4 inch PERMINATOR EVOH TAPE. The adhesion area must be free of dust, dirt and moisture.
Is PERMINATOR EVOH TAPE the same as PERMINATOR BUTYL TAPE?
No. PERMINATOR BUTYL TAPE is a separate product that goes underneath the overlap to hold the laps in place. PERMINATOR EVOH TAPE is the single-sided gas barrier tape that goes on over the seam.
Does PERMINATOR EVOH TAPE block gases?
Its backing contains a layer of highly impermeable EVOH intended to block radon, methane and VOC migration. The data sheet lists a permeance of 0.014 g/(24h·100 in²) per ASTM E96 Procedure B.
Does PERMINATOR EVOH TAPE help with LEED?
The data sheet says it may help contribute to LEED credits EAp2 Minimum Energy Performance, EAc2 Optimize Energy Performance and MRc9 Construction and Demolition Waste Management.
