[QUOTE="quad, post: 16423714, member: 17952"] Yes I agree. Insulating the cathedral ceiling is also not an issue. It does not have to be vented because the entire space is conditioned. You can achieve a high R rating with a cathedral ceiling. The fascia board in this example looks to be at least 8" thick or more so perhaps they were able to squeeze in 6" of rigid insulation between the sheathing which would yield around R30. Up to R60 is recommended for some places near Canada. The fascia board would be thicker as the R values go up. Long screws are required to anchor the insulation to the sheathing and builders place solid blocking at the eaves to prevent the assembly from sliding down. The lowest layer of sheathing is anchored to the roof structure. As I mentioned another option is to get it all preassembled as SIP panels. SIP panels can also bring problems. The sheathing can decay / rot if moisture enters the assembly. Same goes for the manual installation of the insulation panels that I mentioned above. The entire assembly needs to be air tight and stay airtight. One advantage of older homes is they leak air and while this is bad from an energy / insulation point of view it does allow for the inner cavities to vent and moisture to evaporate because air just flows from the interior to the exteriors and vice versa lol! Once older homes are made air tight and insulated it becomes crucial for unconditioned attics and knee attics to be ventilated properly or else moisture could build up and take over in those areas.
