Patrick's Barn: Siding Is Just Around the Cornercomments (5) December 6th, 2011 in Blogs
With unseasonably great weather the end of last week, I used a pair of vacation days to work on the barn. It's amazing how much work you can get done in a four-day weekend. I started on Thursday by installing foam between the girts and covering the girts and foam with a layer of #30 felt paper. This work continued on Friday. By the end of the day Friday, with my wife's help, we had felt and two layers of foam on everything but the gable ends.
I put felt on one of the gables Saturday and on the other on Sunday. Even with the advantages of modern housewrap, including 9-ft.-wide rolls and great tear resistance, I'm a huge fan of felt. Unlike plastic housewrap, felt's vapor permeability increases as it gets wet, which boosts drying potential when you need it.
There was a big rush to get the insulation covered because as I learned from one of the reader comments in my last post, polyiso insulation should not get wet, as it takes forever to dry and starts deteriorating quickly with prolonged exposure to water. The reader who supplied this important information is Dyami Plotke, whose family business, Roof Services, is commercial roofing, so he knows what he's talking about. Coincidentally, Roof Services recently completed the garage roof on Fine Homebuilding's Project House.
I've been cutting the foam to width on the tablesaw. The stuff cuts like butter, but it leaves a lot of airborne fiberglass fibers from the facing. Nailing the panels to the building stirs up the fibers too, so for both tasks I've been wearing a HEPA respirator at all times.
Despite the progress, there's still a lot of work to do, but we're getting close to my original goal of having the building dried-in by winter. If I can get the back door installed and the openings in the shed-roof lean-to buttoned up, we'll be golden.
