A ventilated rain-screen is a way to clad an exterior wall to make it less likely to suffer moisture problems that lead to rot and peeling paint. First, the weather resistive barrier (WRB) consisting of tarpaper or housewrap combined with window and door flashings is installed. Vertical furring is applied over the WRB, and the siding is nailed to the furring. The channels created by the furring strips make an air space that allows the back of the siding to dry out, whether the source of moisture is wind-driven rain, capillary action, or interior moisture that escapes through the housewrap. Screening at the bottom and top of the channels excludes insects.

I like this video. This soundtruck is good as well. Good job man!
I'm still a little uncertain about which wrap is most compatible with the moisture level changes in the structure and surfactants, molds and spores in the sheeting. It would be nice to see a comprehensive review of the difference between rainscreens and barrier envelopes. How are the seals, drains and vents different with the two methods? How can prolonged moisture saturation caused by glass or other surface drainage be managed to prevent moisture rot damage?
Than you for this quick guide. In my case it wasn't so simple, but finally I managed.
great vid. Window install not so good.
thanks
