The vertical rain screen (to allow proper ventilation behind the siding), consists of 2" rips of Zipwall, applied every 24"; in conjunction with horizontally applied Cor-a-vent (to reduce pest intrusion), at the top and bottom of the walls. All systems work in concert to provide an air tight home that keeps the inside comfortable and everything else outside where it belongs!
Close up of the Zipwall rain screen and Cor-a-vent below.
Both north and south sillcocks are sealed with Ziptape and secured in a standard sized j-block, to match the siding.
