Need opinions on whether it is worthwhile to fur down a new vaulted ceiling
As I continue to overthink my new garage, there is one place I still need your input. In case you haven’t followed my recent questions, I have a 16′ x 44′ tandem garage just framed in, that I’m insulating in order to heat the building with a 5000w electric resistance heater. Half the structure features a storage truss where I’ve decided to lower the ceiling to get full cellulose depth.
The other half is a scissor (cathedral) truss where I’m considering doing the same by adding 2×4 ‘gussets’ and doing a multi-angle vaulted ceiling (see sketch). Since the roof deck must be ventilated here, I have to give up 1-2″ of the rather bay to a chute.
Is this crazy to put all this extra effort into the ceiling, or will this make a significant difference in the roof insulation assembly? Assume I’m paying someone to do the work, though I would DYI if I have time. One possible side benefit of this might be that I could dense pack the walls from the attic cavity, right?
