I have 1 1956 ranch home. In the attic the insulation looks to have been rolled fiberglass. However due to age the paper has changed to almost a black cover and when I put my hand down ontop of it it goes right through and there appears to be little left of the original insulation.,if only some dust.
Should I remove this garbage first or just blow insulation over the top of it?
Thanks

Hi radiumglow,

The installation of any new insulation over top of 'bad/damaged' insulation is a bad idea. 1) you lose the R-value. 2) You won't be able to install the PROPER R-value. 3) The installation will be uneven.

Go w/your gut feeling which is to remove the old insulation. If you don't have a Pro do this, make sure you wear the proper clothing and masking to do the job safely.

My best to ya and hope this helps.

PS: It's hard to say if blown insulation is what you should do. Consider cost as well as longevity. If the attic gets wet, blown insulation could lose its R-value rather quickly. Just make sure you consider as much as you can before you make your decision.

PPS: God Bless America!
