Duplex – Storch International, Inc.



Duplex is a core part of our Iconic Blackout offering. While our famous Opaque has the same color on both sides, the Duplex is the same great fabric with a White Back.

Its built-in UV characteristics help preserve its original color while its moisture resistance inhibits the growth of bacteria, mold, and mildew. This fabric requires minimal maintenance but if necessary it can be cleaned with a soft cloth and mild detergent.
