Great video, I've few questions if you don't mind answering about the roof detail and type of insulation, I'm doing a self build passive house in Ireland and am struggling with some of the roof details, it's a vaulted ceiling so the insulation goes in the rafters. 1. What insulation are you using between the rafters? 2. What are your rafter dimensions? 3. Are you using ply/osb above the rafters under the solitex? 4. On the inside, below the Intello, you are showing battens, I'm assuming that is plaster board attached to the battens, if it is plaster board, are you putting a skim plaster coat on the plaster board, does that create a sealed cavity between the intello and the back of the plasterboard? 5. On the under side of the exterior ply/osb, did you use some sort of foam thermal break where the play/osb is connected to the rafter. 6. Are you worried about the thermal bridge of the rafter itself? could you and used some insuleation abouve the rafter but below the ply/osb, something like 25mm PIR for example or would that mess with the dew point? Thanks in advance, I know I'm asking a lot of questions, these are difficult topics and passive houses are relatively new to this part of the world.
Good job on your videos. Question with this video. Why do you have dpc on the purlins. That's not normally required? Thanks. Also could the roof underlay be run on wire netting instead of ply.
Hi Todd. The DPC is a requirement to prevent a chemical reaction between the h3.2 treated pine purlin & iron. The roof underlay can be applied on top of the truss/rafter, extra care is needed to ensure a tight install.
Awesome content.

@@compound__ do you use h3.2 because the purlins sit above the vapor barrier?
