North Texas (Frisco) Attic
I know I’ll never make my money back on insulation, but I have a 4 ton unit upstairs and a 3 ton unit downstairs. With the 105°f days, the 3 ton unit is struggling and I just want to help it rather than upsizing the unit.
I have an asphalt shingle roof and the attic has no ventilation other than the perimeter soffits. I was thinking in order of effectiveness…
- ventilation fan of some sort
- closed cell foam on roof and any attic accessible wall
- more cellulose blow in
Am I on track here? Would it be better to remove the cellulose and foam the attic floor as well? Thanks in advance for any insight!
