New window installation/ wall assembly
I am planning to soon install a large living-room window on an exterior wall. Climate Zone 5 – Windsor, ON. The wall is 1950’s stone veneer but will be brought back to wood framing to re-shealth and insulate, etc.
My plan thus far:
1-1/2” EPS foam
Tyvek house wrap
Window opening flashed appropriately
My question is the detail regarding flange connection. Should a wood piece be fastening to the outside on top of Tyvek and then window attached to it then flashed and later sided with vinyl?
Other questions – rainscreen needed?
