 January 12th, 2015 The production supervisor from Great Northern Insulation came by, using a Froth-Pak which has a smaller spraying gun and longer spraying distance, he tried to address all the ares that were problematic to access by the truck crews. The Froth-Pak foam is a 1.5 lb / ft3. While the purple WALLTITE ECO is 2 lb / ft3. Forth-Pack foam has an R value of 5.5 while WALLTITE ECO has an R value of 7. However, because these areas have access problem, Froth-Pak will just have to do.
Here it is the Froth-pack applied to the opening left behind by the WALLTITE ECO.

December 10th, 2014 Spray foam insulation day 2 by Great Northern Insulation. I am already informed that they are expected to get to first floor but definitely not going to finish at the end of the day. The next 3 week, they are booked solid. So I will likely need to finish the foam insulation in the new year.
Here’s the 2nd floor bedroom. You can see the steel beam pocket / rim joist all fully sprayed. The 2×2 strapping is filled and the 2×2 wood is slightly covered too to give that air barrier. If you keep up to date with building science, you will know that air movement actually degrades the thermal performance of a wall much more than you would think. So a good air barrier is a must if you want a good performance for your walls.

December 9th, 2014 I’ve booked Great Northern Insulation for my spray foam installation. The north wall of the house has to be fire rated and the city inspector does not allow me to put any kind of spray foam in that wall unless I have engineer stamped drawing. For the east, west and south side wall of the house, I’m spraying 1.5″ of foam to seal the wall. Then I will fill the rest of the wall cavity with Roxul mineral wool insulation. Since steel is not combustible, all the steel beams including the ones on the north wall will have the beam pocket sprayed to minimize thermal bridging. On the 3rd floor the east, west and south side wall will be filled with spray foam since the wall there is thinner than the rest of the house. And the entire roof including the one on the 3rd floor will be spray foamed. All the rim joists will be sprayed foamed and the basement wall will be spray foamed.
The produce they are using is BASF WALLTITE ECO or the purple foam insulation that you see in all those home improvement shows you see on HDTV.
With half day of work, they have finished spraying the 3rd floor. Here’s all wall cavity on the 3rd floor. As you can see the entire 2×6 wall cavity filled. with foam insulation.

December 4th, 2014 Finally after months of waiting, the natural gas connection and the meter is finally installed during the last two days.
December 2nd, 2014 The building inspector has indicated that Type-X drywall must be installed behind all metal duct works. So today we removed some of the existing duct works and installed 5/8″ Type-X drywall behind the ducts.
This is the first floor, from the left, you see Type-X drywall behind one furnace supply duct, three return air ducts, and two HRV supply/return duct. We’ve sealed any opening with fire block foam.

November 30th, 2014 More low voltage conduits work today. This is how the conduit on the 3rd floor goes down into the basement. The conduit is flexible, making the installation a bit easier.
