 Drainage Made Simple
With Optimum WaterMaster, vertical ribbons of adhesive form channels for incidental moisture to escape. The moisture travels between the ribbons to the termination of the system where it escapes through weep holes in the drainage track.
At window heads, Parex DrainEdge simplifies the system by facilitating a traditional back-wrapping method and the use of conventional window flashing.
The vertical ribbons of adhesive bond the EPS board to the substrate and the rest of the EIF system is installed as usual.
BENEFITS OF OPTIMUM WATERMASTER:
Proven Drainage Performance
Exceeding the tough ICBO-ES AC24 drainage criteria, Optimum WaterMaster system performs flawlessly.
To pass this test a water-admitting cutout is made in a sample panel. It
then is subjected to conditions of ASTM E 331 simulating 8 inches of rain per
hour, and must provide free, uninterrupted drainage for the duration of the
test. Optimum WaterMaster passed with flying colors!
Testing
Optimum WaterMaster has been completely tested and meets or exceeds current industry standards. And, Optimum WaterMaster is easy to install compared to competing systems. Optimum WaterMaster: Yet another way that Parex provides practical solutions for designers and installers.
