What type of insulation do I need?
I have a 60-yr old brick house with some loose-fill insulation in the attic (a few inches at most). I need to add some more insulation to bring it up to standard.
1. Would it be feasible for me to do this myself or should I get a pro?
2. Is it OK if I put unfaced rolls on top of the existing loose fill? Or should I put more loose fill on? Or do something else?
3. If I do unfaced rolls, does anyone have any recommendations on types, brands, or where to buy for the best price? If I have to do loose fill, do I have to lug the spraying machine into the attic or can is the hose long enough to spray all over?
4. Do I need to buy those plastic things that prevent the soffit vents from being covered up or is that unnecessary?
