Any experience with BASF HP+ Wall system?
We are building a 2 story 1300s.f. Laneway suite on a small midtown lot in Toronto, Ontario climate zone 6. It will be an all electric, high performance build. l am considering the BASF HP+ XR wall system. The spec is attached. It is 2″ of GPS foam on 2″ horizontal wood girts supported on 2×4 on 16 inch centres with 2×6 top and bottom plates. 3″ of WALLTITE closed cell spray foam encapsulates the girts and partially fills the 5 1/2″ cavity as an air barrier. WRB is either taped / sealant of rigid foam joints or tyvek then furring and rainscreen. It appears to meet my performance requirements and leaves a 2 1/2” service cavity under the drywall, all within a 2×6 wall. Does anyone have any experience or opinions on this wall system?
