Spray foam wall and 2x6 framing: How to seal stud-to-stud cracks?

I spray foamed my entire house. Roof trusses, wall cavity and even the floor.

We're just getting ready to do electrical and mechanical rough in and the spray foam guys are going to come back and scrape any exposed foam off the face of the studs, and also seal the windows and stud-to-stud area.

What they are planning on doing is using acousti seal where 2 studs sit side-by-side and then put tuck tape over the acousti seal.

How can I seal this space w/ moisture in mind?

Hi All,

I am working on renovating our second floor which includes putting in a master bathroom and gutting and redoing an existing 2nd floor bath. It is a 1952 cape with brick siding on concrete block. The masonry walls are completely uninsulated in most cases. I have taken advice from the GBA site while researching various issues associated with this project and figured this would be a good place to ask about this.

Small spots on inside of Weathershield double pane windows with argon gas

I purchased and installed vinyl clad Weathershield windows. They are showing spots on the inside of the window panes. Has this window failed or is this the result of the argon gas failing. I notice them at the bottom few inches. I am attempting to sell my home and buyers are concerned at what might be going on. They will rely on your opinion.

thank you, Gene.

Installed R-60 insulation in attic... now using AC more than before

I had R60 blown into my 1000sqft attic where there was previously only about R11. Baffles were installed in almost every roof rafter. Air sealing of attic floor was performed. This is a low pitch asphalt shingled hip roof over the whole house.

Insulating between chords and webs of a truss joist

I am using 16 inch truss joists in a cathedral ceiling and wondering what is the best way to insulate the spaces between the web and chords.

Was going to create a template then cut the pieces out of 1.5 inch EPS.
I was thinking that there would be not be more than an eighth difference in variance in the trusses.
I would use batt insulation for between trusses.

What about splitting Roxul to 2 inches and then cutting?
It might be easier to work with.

The spaces are quit small.
About 8 inches tapering to nothing over 4 feet.

Any suggestions?

Blower door question

I'm going to have a blower door test done eventually. Do they have a cheap, repeatable way to block flapper dampers, used to provide makeup air for bathroom fans and a whole house fan during an blower door tests? My house is a bit experimental in using several large ones for the a whole house fan. They will have custom insulated plugs that block them off in winter, so this is more of a general question and not for my house specifically.

Using SIPs for my upcoming roof project

I have a 4'x 12"pitch 50 square ranch roof. Open interior rafters and existing T&G decking above rafters. I will be installing a metal roof over and am interested in a R50 SIP as insulation above the T&G board decking. I need to know the best way to seal the exterior (top) of the T&G boards, and then how to seal both the underside and top of the SIP Panels. I also need your suggestions on venting continuous soffit to ridge plenum. Perhaps a "Cold Roof" above the SIP panels and below the metal roofing?
