New Technology with a Proven Concept

Aggre-flex Commercial Drainage is a high performance Exterior Insulation and Finish System with a trowel-applied WeatherStop air and water barrier. The water barrier helps drain away any incidental water entering the system.

Master Wall WeatherStop Tapes are used around openings and penetrations.  This peel and stick type tape has a scrim coating that the base coats bond to.  Drainage channels are created when the adhesive is applied vertically.

This system is best suited for high-end commercial properties where long life and a high performance secondary water barrier are desired.
