Insulation question
 
Hi,

My house attic is extremely under insulated. Its only about an r-11 right now. It gets very humid on the first floor in summer. I am planning on adding another r-19 blown in cellulose. I would do more but I can't afford it right now. Do you think I will noticed a difference by adding this?

Yes if there's proper roof venting.
Really need to go back and add your location to your profile for any useful advice.
Go to quick links to edit.
You need soffit and a ridge vent. Also baffles to hold back the insulation so it does not block the air flow to the ridge vents.
