Matt Sharpe replied to David Butler's discussion Does IRC preclude use of spray foam to insulate rim bands in unfinished basement? (re: ignition barrier)
"I also believe that the exception Peter refers to in R316.5.11 is an exception to the thermal barrier requirement. So if you don't meet those criteria for an exception (thickness of foam, density, or flame spread) then you just install the…"

Matt Sharpe replied to David Butler's discussion Does IRC preclude use of spray foam to insulate rim bands in unfinished basement? (re: ignition barrier)
"use a spray foam that is approved as an ignition barrier … and while you are at it use a foam that has low Global Warming Potential, something like http://sesfoam.com/download/msds-sucraseal-0-5-lb-spf-2/?wpdmdl=1069 ; that's not an…"

Matt Sharpe replied to Dav Camras's discussion Adding blown insulation to poorly installed batts?
"I have seen this done well too and may be the best cost effective approach considering the insulation is in good condition. It does have value if installed like it was meant to be. Air tightness is the indicator of success. If you are good with…"

Matt Sharpe replied to Dav Camras's discussion Adding blown insulation to poorly installed batts?
"Best practice would be to remove the old poorly installed stuff to gain access for comprehensive air sealing, eave vent baffle installation, chimney air seal and insulation dams, etc. and then re-insulate with blown in. If best practice is not your…"

Matt Sharpe replied to Bob Reuther's discussion log home roof insulation
"Agree that its hard to help without more information. Pictures? IR images? Do IR images show air bypass or insulation voids? or both? If its T&G with exposed beam rafters it would suggest the T&G is the roof sheathing as well as the finish…"

Matt Sharpe replied to David Butler's discussion How would you insulate this roof?
"The residential stuff is thicker than normal foil but not as rugged as sheet metal. It could certainly be damaged if scraped or dented in transport. I've never seen the commercial grade stuff with 4 mil surface. "Embossed" might be…"

Matt Sharpe replied to David Butler's discussion How would you insulate this roof?
"Taped seams would be pretty obvious. I have seen vinyl 'T' strips used at seams which look decent. For a glimpse of what this product looks like on foundations check this out, https://youtu.be/5XFVdUC5upM"

Matt Sharpe replied to David Butler's discussion How would you insulate this roof?
"That would probably go into the category of "ask your local code official". I think the same rule applies to walls and ceiling, which is equivalent thermal barrier to 1/2" drywall. We see it used here on foundation walls and ceilings…"

Matt Sharpe replied to David Butler's discussion How would you insulate this roof?
"You could infill between purlins against metal roof with cheaper foil faced poly-iso in addition to the white finish Thermax insdie of that to get better R-value if needed. Could be a better air sealing effort of you did this as canned foam can be…"

Matt Sharpe replied to David Butler's discussion How would you insulate this roof?
"I'd work on the inside. 2.5" Thermax white finish polyiso can be left exposed and looks decent (better than bottom of metal roof), provides proper thermal/fire barrier (at least here it does), can be air sealed at seams and seams covered…"
