Below is the super damper and the insulation and 14 inch duct that it will feed into.
Here Sam and Pete are installing the super-damper. It fits and looks good.
Here is the ceiling in the addition and bedrooms. Air sealing is a major challenge and of critical importance. Both Peter and I have seen poly film degraded and brittle after 30 years, so we have adopted a double system. First is the layer of plywood on the ceiling that will help support the weight of almost 3 feet of blown in cellulose. The plywood also has a very low vapor permeability. So we sealed the seams with mastic and then put poly film over it, to boot.
After the ceiling, we had to seal the perimeter to the air barrier on the wall. As a backer for the foam, we put in some fiberglass bits. Here Mike looks like he's butchering some wild cotton candy.
Sam.
Feeding the insulation blower is actually not such a bad job. Here we see Peter doing a not bad job on this not such a bad job.
And Mike had to keep busy making use of the cellulose that kept blowing out the hose.
And we had to prep the air exchanger tube ends. Sam nicely built a foam box around each end to provide enough insulation behind them and to keep any moisture off the wall. We decided to wrap the perforated exhaust tube in poly film in order to further isolate the moisture from the wall framing and insulation.
And we also built a foam insulation box around the dryer vent. This serves to isolate the moist air from the insulation and, also, to provide some opportunity to replace the vent tube.
Not pictured: Plumbing and wiring. I accomplished some wiring in the bathroom and also redid most of the copper plumbing with PEX. The lines are much more streamlined, color coded, and fully insulated, even through studs and floors. It's something I'm proud of in a plumbing geek kind of way, but it is not terribly photogenic. Maybe some pictures next week.
Got the West side done!
And we got more roofing installed!
