I bought a 1904 house and renovated it. When doing the electrical I found someone did this in the walls at some point. I replaced all the windows and filled the Attic to R50. My utilities during Canadian winter are nearly half of my friends homes that were built in the 50s to 80s. My highest bill this winter was $251, 1300sq ft plus heating a 600sq ft garage. One friend for example, with a 1950s home (new windows, original insulation) was paying $400/mth, 900sq ft, no garage to heat.

Great question! By using a fill tube to inject cellulose into the stud bays, the good thing is that we actually find and locate the fire stops. We simply drill an additional hole above the fire stop and dense pack the rest of the stud bay above it. Andy
Correct, I am biased. I previously installed injection foam for two different companies and witnessed it fail (shrink badly) on several occasions (within hours of the install in one case). I'll enclose a link of how this stuff looks after installation below. Our goal is to insulate the walls once and not have to go back. That is why dense pack cellulose insulation is the most trusted way of insulating closed cavity spaces within the building science community. Go to Chapter Failed Foam Injection at 4:48 in the video. ua-cam.com/video/YsVCTGRR7fc/v-deo.html By the way, the customer paid the foam injection company about $7,000 to insulate the same areas that we are redoing in this video. So yeah, we're biased. Andy
Thank you! If you live in the Pittsburgh area give us a call! In terms of cellulose insulation being a fire hazard, the opposite is the case. Because it is treated with boric acid it cannot catch fire. If you do other searches on youtube you'll find where people hit this stuff with a blow torch and all that it will do is smolder. It will actually reduce fire risk in a home, because it will eliminate the ability for flames to use exterior wall stud bays to envelop a home. It will increase the safeness of the home fairly dramatically in that sense. Andy
@@insulwiseenergycomfortsolu3293 I been following awhile and watching most the videos in your channel. I would love to have you take a look at our home but I don't know if you could come to our home as we don't live close to there. What is your number?

Hi there, do you mean that the walls were done with injection foam or dense pack cellulose?
@@insulwiseenergycomfortsolu3293 Cellulose. Found the walls were packed when running all new wiring. And when doing the windows, found 2 layers of 3/4-1" shiplap and then new aluminum siding over that. This place is built like a tank.
How do you get through the firebreaks?

His bias is written on his coat sleeves, since he immediately went into the cons of foam and his voice changed when describing it.

I am interested to hire you and your company. My only question is this a fire hazard?
