Dense vs Loose Pack in Cathedral Unvented Ceiling
Plus on the exterior, Intello Plus on the interior, and spray foam at the box ends — I’m contemplating whether loose-filling the ceiling might be a feasible alternative to dense-packing. My reasoning is that loose-filling could potentially offer better R-value, while the existing membranes should maintain the necessary airtightness. This would also reduce the labour and skill required to apply the cellulose.
Perhaps it’s worth noting that the north slope of the roof is 16″ TJIs placed 24″ OC and the south slope is 16″ TJIs placed 16″ OC.
