Insulating truss joists 16″ on center — Best way?
Batt insulation for 24″ o.c. The 2x lumber is 23″ wide. The truss joists I’m looking at are 2×4 lumber 24″ o.c. The space between the trusses is 21.5″. Does anyone know if R-19 batts are available in 21.5 or 22″? Seems like squeezing a 23″ wide batt will not work well.
Also the tiger wires used on 2x lumber will not work well on a truss. Is there another method of holding the batts up to the floor?
