Moisture management starts with the wrap. HardieWrap® weather barriers deliver the performance you've come to expect from James Hardie.

GreenGuard's business is to help you build the most protected and durable walls possible. Their residential line is filled with products that help block water and air infiltration and add insulating power.

Lamb & Ritchie flashings prevent the entry of water at areas on a roof where two components join together or intersect.

MFM Building Products provides an entire "envelope" of weather barrier products and flashing products.

As the leader in the through-wall flashing industry York has led the charge to create flashings that are compatible with the air barriers and insulations that populate the cavity wall.
