PERSIST building method
I am reconsidering using OBS faced SIPs for wall/roof construction in climate zone 5A (Rochester, NY). The building design is 1500 sq. ft, frost-protected, slab-on-grade – monolithic pour. Shed roof, one floor plus loft.
I am interested in the PERSIST building envelope method but am having trouble locating construction method details.
1: What is the best choice for exterior insulation? How is it attached to exterior sheathing? How is it laid out (pattern) and sealed?
2: What is best choice for exterior sheathing? Material? Thickness?
3: Are there special considerations for plumbing vents and other penetrations (ductless mini-splits, direct-vent gas space heaters?)
4: What is the best choice for the SBS membrane? Can the same product be used on the roof and wall sheathings?
