Insulating options for open-web floor trusses
Would greatly appreciate the collective advice from the readers of GBA on the following:
I have 18″ open-web floor trusses installed in a unconditioned garage with a conditioned room planned for above. Have had many opinions from insulation reps on how to insulate. Foam, flash & batt, blown cellulose/fiberglass, sprayed rock wool, and fiberglass batts.
I am leaning towards blown cellulose, but have concerns about settling over time. The garage walls will be insulated with blown insulation but I am not planning to heat it. Not sure what is the most feasible solution that balances economic concerns with insulation needs. I am located in zone 5.
Thanks for your thoughts on this…
