Water management building wrap

The invention describes a building wrap used between a house's frame and its exterior siding. It consists of a breathable membrane combined with an extruded plastic netting on one side. This netting forms stable vertical channels, allowing any water that penetrates the exterior covering to drain harmlessly down and away from the building structure.

Why it matters: Since 2006, advancements in polymer chemistry and extrusion manufacturing processes may allow for more durable, cost-effective, or environmentally friendly materials for the drainage structure. This could make the specific design of the netting more economically viable to produce and integrate today.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateCustom extruded netting, membrane lamination
