Detail at REMOTE Wall & Lower Roof Connection

I'm in the design state of building a REMOTE house in climate zone 6A. I'm looking for a detail showing a lower roof line connecting to a REMOTE wall. How is waterproofing on the roof best dealt with at the wall intersection?

I've seen photos showing installing the EPS before the lower roof truss to allow for continuous insulation but cannot find anything showing how the waterproofing on the lower roof is then tied into the REMOTE wall.

Cellulose vs. stabilized cellulose?

Most of the cellulose going into walls here is stabilized cellulose. We had a new insulation contractor tell us this week that he will only put in loose cellulose in walls. (by loose I mean no glue). He said he nets the stud cavities and blows it in at 3.5#/inch, so there will be no settling over time.

He also briefly mentioned that 'they' were starting to find serious issues with the stabilized cellulose product, but we didn't get into that.

Any issues with this method? How do I know the density really is 3.5#? Is there any way to check it?

Will it not settle over time?

How best to balance an HRV's intake and Exhaust?

I got my ecoEnergy Retrofit final energy evaluation back, it's a Canadian retrofit program. The house scored an 84 out of a 100. The evaluation report doesn't actualy provide an meaningful information, just the score which is used to calculate your rebate. Most of the marks were for the geoexchange system I put in!

I called up the evaluator and was able to get some useful information from him. The ACH50 was 1.85, the ACHnatural was 0.080 and the equivalent leakage was 72 in^2.

Tiling a painted floor

I have a basement that I would like to tile. The previous owner painted over the floors and said that there may be old lead paint underneath the upper layers. Because of this, I'd like to leave the paint undisturbed which, from what I gather, will present some problems for tiling. If I want to keep the paint in place, does this limit me to floating tiles? I have also heard of glue down cork for use in basements. Would either of these two options be good alternatives or might there be a better option? Thanks.

Tank or tankless water heater?

It appears my water heater is coming to the end of its useful life. I currently have a tank style gas hot water heater. I've been reading about tankless ones but get mixed reviews on whether it's actually worth the upfront costs.

I mainly like it for the fact of having hot water on demand, however, don't want to buy something that isn't worth the investment (I realize I probably won't fully break even on it). Is it worth getting the tankless?

Thanks in advance for the comments.

Insulated chimney

Hello Martin,

I'm considering wrapping this chimney in 2"- 3" of Roxul or Thermax or spray foam insulation before we cover it w/ sheetrock. Code is likely to require Roxul I think.

The picture shows I'm standing on the 2nd floor and shows the chimney as it comes up from the 1st floor and then goes through the 2nd floor ceiling, into the attic. This house will be getting an unvented attic, w/ 6-7" of CC spray foam on the roof decking / rafters, so the attic will be regarded as conditioned.
