Pink blown in wall insulation

[Jeff Thies]

I have a friend that took my advise and blew in wall insulation. He didn't take my advice to use cellulose though. Or to have me help.

I haven't seen this yet, but he cut 3" holes and used "pink" insulation. I'm thinking that must be fiberglass. To do his house walls he used 4 bags out of the 20 he bought. That seems to be the definition of loose fill, very loose. It's hard for me to tell though:

That seems to indicate higher coverage than what cellulose would have done.

If he screwed up. How to fix? My thoughts are running to switching to cellulose. What would have been the proper way to blow in fiberglass? I can't seem to Google complete instructions for this.

The data sheet you linked to has seems to have all of the info you need to determine if it was properly applied.

Assume 3.5" walls then it says max coverage for 4 bags would be 267 square feet.

I wanted to top off an attic where ProPink was used and was unable to find anywhere it was sold. It's apparently considered a "pro only" product and has to be installed by a qualified installer.

I suspect your friend didn't use the right kind of blower and didn't get the required density.

[Jeff Thies]

I think, but don't know, that you need to feed a hose to the bottom of the bay and then lift that as it fills. That is a much different proposition than dense packing cellulose. The lack of instructions lead me to your conclusion also. Oddly, I can't even find the dense pack coverage charts for cellulose, Green Fiber seems to have removed that.

I'll head over later with my IR thermometer and take some measurements, but my friend and myself think very differently.

Yes, the proper way to drill and fill with any product is to call the man who does it for a living. Drill and fill is not a dyi project.

I had little trouble with the cellulose dense pack. It's not rocket science. YMMV.
