ProBuilder Product Report: Insulation & Housewrap

Installed into building exterior wall assemblies, often at the same location in which building felt or paper would be, is Carlisle Coatings's Barritech VP. It provides a continuous air and water barrier that allows passage of moisture vapor while eliminating the penetration of liquid moisture. This chemistry allows Barritech VP to keep rainwater out of the building envelope, while allowing indoor moisture to escape.

Installing just like typical OSB wall sheathing is Georgia-Pacific's Nautilus. The wall sheathing panels feature a pre-applied weather-resistive barrier and tape using the similarly-named Nautilus 3-inch wide seam tape. The installation process is faster, according to Georgia-Pacific, thanks to the visible nailing guidelines and the elimination of a two-step sheathing/building wrap installation.
