I am curious about other's experience as I get asked the following question all the time: Is it necessary to pull out a poorly installed batt of insulation or will a subsequent blow of cellulose or…Continue

Low Leakage home with cathedral ceiling

Started this discussion. Last reply by Rob Buchanan Dec 21, 2017. 5 Replies

I am curious/concerned about advising a tight house (addition) with a cathedral ceiling. I understand that normally, one should keep a 1-2" gap in the rafter bay above the insulation as an air gap.…Continue

"I agree, it is wasteful to remove and dump old insulation. I still does its job. Air sealing is important so after that's done blow cellulose and a good job will be had for a much lower price."

Matt Sharpe replied to Dav Camras's discussion Adding blown insulation to poorly installed batts?
"I have seen this done well too and may be the best cost effective approach considering the insulation is in good condition. It does have value if installed like it was meant to be. Air tightness is the indicator of success. If you are good with…"

Ed Minch replied to Dav Camras's discussion Adding blown insulation to poorly installed batts?
"After lifting specific batts for blower-door/IR/experience guided air sealing, (rarely with 2 part foam) my crews will use a narrow rake to push batts down against the ceiling and around wiring and framing anomalies.  Then we will blow on top.…"

tedkidd replied to Dav Camras's discussion Adding blown insulation to poorly installed batts?
"What Matt said. Remove everything. Air seal. Ideally with 2 part foam. Blower door test to find remaining leaks. Install fresh. The insulation has little value without air sealing. More of worthless is still worthless. We are removing…"

Dav Camras replied to Dav Camras's discussion Adding blown insulation to poorly installed batts?
"The "sad" part is the attic insulation is new and clean. The house was remodeled a few years ago and they want AC b/c it is so hot. Poor batt insulation quality with big skylight shafts have to be part of the problem. "

Matt Sharpe replied to Dav Camras's discussion Adding blown insulation to poorly installed batts?
"Best practice would be to remove the old poorly installed stuff to gain access for comprehensive air sealing, eave vent baffle installation, chimney air seal and insulation dams, etc. and then re-insulate with blown in. If best practice is not your…"

David Butler replied to Dav Camras's discussion Adding blown insulation to poorly installed batts?
"When topping off an existing ceiling with batts, there's a cost to pulling out the old. True, the blown-in may not fill in all the gaps, but you'd likely get more benefit by spending that money on additional blown-in on top. A more worthy…"

Adding blown insulation to poorly installed batts?

I am curious about other's experience as I get asked the following question all the time: Is it necessary to pull out a poorly installed batt of insulation or will a subsequent blow of cellulose or fiberglass fill in most of the missing gaps? What are people's experiences?Thanks. See More

"Not exactly for amature's or hobbyists. It may be more accurate because it's monitoring each circuit independently, but much more work and really should be installed by an electrician. This is probably a very good industrial solution."
