Insulation questions on a gut rehab

Hi all,

I'd like to comment on the usefulness of the website while conducting my research during our gut-rehab;we have been reading a ton of information about best practices during construction and what we should and should not do.

Some facts about the house:

    Tri-level brick home in Chicago

      2x4 walls

        2x6 roof rafters

          roof pitch is 4:12

            Forced air HVAC

              Roof is 5 years old, one layer of asphalt shingles

                Home built in 1965

                Some facts about the project:

Low-slope "warm" roof build-up clarification

We are advancing on the planning stages of a new build project in climate 4C (near Vancouver, Canada). Thanks to the many articles and Q&As on this site I've got myself comfortable with most outstanding issues we are facing in developing our roof and wall build ups. This is a small building used as a holiday home, not fully occupied in Winter.
With that in mind any feedback from your good selves would be appreciated.
The roof is a mono pitch (shed style) front to back at just 1:12 with no "rafter" space to hold insulation
Build up:
- Exposed 3X8 Douglas fir beams

EPS foam density for use under concrete slabs and around stem wall

Hi everyone,

I'm right at the point where I need to purchase some EPS foam for our slab foundation / stem wall on a residential net zero project. I've read and posted on the project in the past and there seems to be a consensus that Type II EPS foam should be fine from a compressive strength perspective in both applications.

To vapor barrier or not to vapor barrier?

Hi all,

Pardon my ignorance or lack of proper nomenclature, but have a question regarding vapor barrier/retarder (I know they are not one and the same) and insulation.

Duct Insulation Sleeves - Black PP or Reflective Foil?

Right out of the gate, I am NOT talking about foil faced bubble wrap duct insulation. This question is specifically in regards to FIBERGALSS INSULATED DUCT SLEEVES. :-)

I see generally two types of fiberglass insulated duct sleeves available; those with some sort of plastic covering and those with a reflective foil type covering.

I would assume the foil covered types might be intended for use in an unconditioned attic with high summer temperatures? But my question applies to using these products within the conditioned space.

An example of both products can be seen here:

Critique this rough floorplan

We are in beginning stages of choosing an architect/project manager, but we have some wishes on how we want the floor plan to be.

Being amateurs, I'm sure there are mistakes. Please critique.

Our goals, wants and needs:

- make the house as small as possible, ut with enough room for everything we need/want
For example, we want a study, though that is not common practice here. We took that good practice from USA and like it a lot.

Building a new house, looking for opinion on insulation/exterior foam combinations

I am currently in the process of designing a new home. I built one four years ago that we have decided is too big and inefficient for what we need. This time around I am looking to build small, simple and efficient. The house will most likely be framed with 2x6 walls, however I would like to maximize R value of that wall.

How to vent an attic that has no eave?

In an older building. The problem is ice dams more so than energy cost reduction. The roof design is more complicated than I can explain easily here.

I am considering using these vents. however they look designed for new not retrofit construction. Any experience with this type of vent.


thanks in advance
