insulation goes in
6 August 2010
This past Wednesday, Thursday and Friday I had a visit from WarmTech Solutions, of Yarmouth. They had some ideas about combining different types of cellulose insulation in order to help improve our home’s thermal envelope. By rough linear footage of wall, and square footage of ceiling, I reckon that the second floor’s insulation improvement will be about 55% and 67% of the envelope. These numbers may be a bit of an underestimate though, considering I found the knee walls of the attic studio nearly 2-foot deep in R-3.5 blown cellulose, and the crew said they were able to send a whole LOT of cellulose down some of the stud bays – likely into the neighbor’s walls as well. Nice job!
Types of insulation being used here:
1) A wet-application dense pack cellulose. Cameron from WarmTech explained it was derived from old newspapers, which would make it a better version of what was in the walls before (photo below). Also see post #4 from 14 June.
2) A dry application, pressurized dense pack cellulose. Sent into netted spaces between the attic floor joists all the way out to under eaves.
3) An expanding foam insulation for air sealing. This was applied around the eave openings, in the basement at the perimeter joists, and anywhere connecting the different floors of the building (fire-break).
So just a heads-up as far as insulating goes- cellulose is a bit dusty and might take a little pressure or water to get going, but other than that, totally likeable.
