WeatherSmart® Drainable takes protection against water intrusion to the next level with a patented drainable pattern that quickly directs water downward and out of the wall cavity. Featuring a spunbond polypropylene fabric, WeatherSmart Drainable is suitable for use in any climate and behind all exterior claddings, including fiber cement, vinyl and wood siding. It's an integral component of the wall assembly behind brick, stone and stucco.
When used as part of the Henry® 1-2-3 Moisture Control System™, WeatherSmart Drainable is backed by an industry-leading 15-year warranty. Repairs are covered for both materials and labor with a single point of contact.
