Over the past few weeks, we have been working on installing the vapor permeable air barrier. We were fortunate to be joined by Drew and Leo from Henry Company who demonstrated the proper installation methods. Drew stressed to make sure that the blueskin was placed the correct way so that the company name was legible. Leo just laughed and said he used to say that too when he was a new guy. We used Blueskin VP 160 which is both air tight and water tight but is highly permeable to water vapor.
The process begins by applying an Aquatac Primer, which is a polymer emulsion based primer for self-adhesive membranes, around the window and door openings, and around the crease between the rim joist and the start of the SIPs. Next a strip of Blueskin flashing is put along the areas that have been primed. Finally the house is ready for Blueskin VP, which covers the rest of the surface area of the house including the roof.
We were also fortunate to be joined by Darren Getty from Pella windows who showed us the proper window installation methods. The windows we used have a higher tint so that they reflect light more efficiently. Currently, all of the windows have been installed, but we are still working on wrapping the house and roof.
