Adding Loose Fill Insulation to an Attic

[DyslexicLunatic]

Gee, you think you might have shown the prep stage so people understand what they do before blowing in the insulation! Oooops!

Do you need to install rafter vents and be concerned with bringing the insulation right up to the roof decking if you do not have soffit vents? My house only has eve vents on either side and a ridge vent was just installed with my new roof this spring.

There doesn't appear to be any room to add soffit vents under the overhang and there have been no rot or mold issue with the current set up. My plan is to blow in insulation to bring it from the 6" depth to ~16" which should give me R50 or so

@gpaul721 Ideally you should have vents at the eaves. If it were my house I would keep what you have. If you live in a northern climate you will want to keep insulation away from the underside of the roof. The ENTIRE underside of the roof sheathing should be COLD, that prevents snow from melting (on the roof immediately above your exterior walls) and then freezing into ice at the eaves. Check out Fine Home building magazines at your Library for some great info about this.

Just a tip! Use radiant barrier on your loose fill insulation! it makes a bigg!! difference..

You have to install properly. Plus fiberglass will never burn.
