Perlite for walls vs Dense pack Cellulose

Hello-
Has anyone used loose fill perlite for wall cavity insulation on wood framed exterior wall. I am interested in the least toxic insulation for the walls. But I am a little concerned about the moisture retention capabilities of perlite. Does the perlite dry out quickly in a normal framed wall?

Also, does dense pack cellulose have less capacity for moisture retention?

Lastly, has anyone used loose fill perlite for attic insulation.

Thank you to those involved with the elimination of all of those asian-alphabet, unreadable, virus-like comments that had taken over this site this past week. I enjoy checking out the question section of this site when time allows, and when I saw those "comments" I moved on to other things. THANK YOU !!!

Using below grade SIP for full basement

We are planning our single level lake home in northern Minnesota. 1200 sq. ft. walkout. 11000 HDD Zone 7.

I'm fully aware of the traditional basement options; block, poured, and ICF their plusses and minuses having worked in the masonry field when I was younger.

Question: Has anyone had any experience using SIP's for below grade?

Thanks!

Any vented attic air sealing tricks? And recommended R-values? Blown fiberglass?

I am building a home in climate zone C4 and am getting ready for insulation at last. I have wrapped the house with a layer of 1" xps already, but am getting ready for the rest. The local insulation contractor is pushing blown fiberglass over blown cellulose, what do you guys think about this, I have heard it settles less. Most of the house has cantilevered scissor trusses. Do you guys have any good practices for air sealing around all of the electrical lighting boxes (not cans) that I have installed in the ceiling?

Finishing a damp basement

I have a client that lives in an early 1900's home here in Minneapolis. Her current foundation is stone not block and is quite rough on both sides. She wants to finish the inside of the basement and add framed walls and drywall. She gets a minor amount of dampness on the wall and it is virtually impossible to waterproof this wall since it is such a rough stone. She does not get standing water but just dampness on the wall a times.

Insulating cathedral ceiling

I have a late 1970's contemporary home that has non-ventilated cathedral ceilings that do not connect to a ridge vent - they do have sofit vents but don't see how that helps. From the middle of the house there is a 2nd floor where I can get to the point where these roofs join and can see there is little to no insulation. I believe I can remove what is there with extension poles.
My question: What are my insulation options. I assume some type of insulation that can be sprayed (foam or wet ?)

Any suggestions appreciated.

Thanks,
Dan

Ducted or ductless?

Hey guys,

Still working on my house specs for my 2800 sqft house just outside of DFW. I really want to have my ducts inside the conditioned space but this seems really difficult unless you foam the underside of the roof. So, I've seen these ductless units and wondering if it's practical and maybe less costly. The big challenge, I think, would be the house is single story, spread-out and lots of rooms. Thoughts? I tried to attach the pdf floor plan but it failed. If you want to see the plan I can email, etc.

Thanks,
Shawn
