200 + year old home with no insulation in walls

I will be removing the exterior sheathing and addressing air sealing & insulation from the exterior. Interior walls (plaster &wood lathe) are in good shape and the windows are not being replaced. I live in the Seacoast of NH. I plan to install plywood sheathing, typar, rain slicker (rain screen), combination of vertical grain siding &shingles. The part i can not make my mind up on is the insulation. I would rather not install exterior insulation although i realize that is preferred. I am not looking for passivhaus standards just to make the best of the space i have.

Insulating a non vented vaulted ceiling.....?

i am hoping to get some feedback on the issue I have found in my house while redoing our dining room. The electrical issues that can be seen in the photo's are one of the reasons I pulled the drywall to begin with and are being corrected. My dilemma at the moment is how to properly insulate this area of the house.

Home Air quality test kits... any good?

I am looking to get some insight to what is floating around in our home. We are planning on having a baby soon and after some remodeling and asbestos removal, I want to make sure everything is ok.
To have a pro come out and test, can get very costly and so I have found a few companies that offer home test kits. These 2 companies that provide testing kits had the most information available.

Renovation, exterior Rigid while dealing with setback codes

Hello all,

I'm still working on my garage plan. We now plan to add a room above our garage.

I was looking at wall builds and like the exterior rigid build the best for durability and thermal bridge advantages. However, this is going to be a room over a garage "renovation", and under building codes, my renovation/addition cannot be any further into my sideyard setback (it already is grandfathered in).

However, I suspect that they would not tag a couple trim "details" encroaching.

Bonded Logic insulation products

Is anyone aware of any health issues that have been reported with the use of the Bonded Logic cotton insulation products? This is the insulation made from blue jeans (and thus, is blue in color). I had read something a long time ago and can't seem to reference it. We are looking for a formaldehyde free, low, or no, VOC exterior duct wrap for the attic HVAC systems. I am guessing that Johns Manville Formaldehyde-free duct wrap would be a good choice but wanted to look at non-fiberglass as well. Thanks.

Ideal wall for 3C climate zone and in seismic zone

I am a homeowner interested in your opinions on ideal wall insulation for San Francisco in the 3C climate zone.

We are planning a new addition with 2 x 6 walls which I would like to fill with dense, wet spray cellulose insulation.

I have asked everyone I can locally about using one 1 inch polysio on the exterior and I always get - "not done in this climate", "not seismic-safe" "will not pass inspections due to shear strength requirements".

Can 1 inch polysio be put over the top of plywood and the waterproofing?

House to be built is located in central OH ... zone 5 cold climate ... HDD of 5708 and CDD of 797. Aiming for the following R-values: basement sub-slab (R-10), basement walls (R-16), above grade walls (R-32) and attic (R-49). Planning 2" of XPS rigid foam under the basement slab, 2" of DOW Perimate XPS rigid foam outside the poured concrete foundation walls with a rigid foam lining the interior basement wall. Is EPS recommended over XPS or Poly-iso for the interior basement walls to aid in drying towards the interior?

Comparing Window performance

I am trying to compare apples to apples on various triple window brands. When folks here quote the U value of a window I assume they are talking about Uw (whole window). I was told by a vendor that that value varies with the size of the window. What window size are people assuming when they say the U is a certain value?
