Question IS BLOWN IN INSULATION AS GOOD AS THE ROLLED OUT STUFF?
DOES THE BLOWN IN STUFF HAVE A HIGH R-VALUE?
I HAVE A VENT IN THE TOP OF MY ROOF THAT RUNS ALONG THE WHOLE ROOF. IT IS ABOUT A 4" GAP THAT ONLY HAS SHINGLES OVER IT, IS THIS ENOUGH VENTILATION TO AVOID ROT OR DO I NEED MORE WITH MORE INSULATION? I DON'T SEE ANY SOFFETS ANYWHERE, ARE THEY NEEDED WITH THAT VENTILATION? IS THIS VENTILATION POOR{CHEAP}?
Answer Hi Erik:
Generally, blown-in insulation, when properly installed, is better than rolled because it does a better job of filling in all the gaps. There are lots of different types of materials and application methods, so you will need to understand the specifics of the type you are considering.
If you are insulating the floor of your attic, and the attic has a ridge vent, that should be sufficient as long as you have good air flow across the ridge vent. If you are insulating the underside of the roof, then you need to take extra precautions in order to ensure that the air flow up the backside of the roof, is adequate and clear to the ridge vent, including new soffit vents at the bottom end, in order to ensure it carries away any moisture that may develop on the cold side of the insulation.
I hope this helps; good luck with your project. You are doing the right thing to add insulation .... very smart; good choice.
Thanks,
PB
