ceiling insulation question


The company is very professional and is the only company in my area that is authorized by national grid to do work.

They did leave 3" space around the recessed lights ..they covered each light can with an aluminum box but they to leave top of the box, they created , open to attic. so the attic floor has 10 openings now. I dont think the can need to be exposed .

Although I was not present when they blew in the insulation, i dont beleive they went through the vent. I will ask them tomorrow to be sure. They spray foam in a lot of areas in the attic floor under the insulation creating an air seal. I asked them if we should block the luvers in the attic ...they said there was no need...

There were some surprises. some of the exterior walls had some insulation ...one wall had a brick wall inside the cedar exterior...so they couldnt blow in any insulation as there was not much space.

I think my heating bill will be atleast 50% less.

When they blew the insulation in, did they bring the hose through the house or down through a vent in the roof? I'm just wondering because so far we've talked to two different companies about doing the blown-in insulation in our attic. One said they come in through a window and the other said they come in through the roof.



I'm glad your house is warmer now. It will be interesting for you to compare your old utility bills to the new ones. Hopefully the $600-$900 heat bills will drop drastically.
