Sloped ceiling insulation
In climate zone 5 we have renovation of a cape home and a suggested sloped insulated roof design as following:
Soffit to ridge ventilation with baffles the entire way. Blown in fiberglass insulation in 2×8 rafters 16 oc. Underside of rafters covered with 1.5″ Thermax under the entire roof.
Question: Where is my dew point in this assembly and are their any concerns with this type of air barrier and insulation design?
