The vapor retarder prevents the moist air from reaching the part of the wall that is cold enough to allow condensation.lavarderahttps://www.blogger.com/profile/07241073948874188058noreply@blogger.comtag:blogger.com,1999:blog-38363189.post-55525390379964823922012-01-10T15:17:25.895-05:002012-01-10T15:17:25.895-05:00thanks, that article is very useful for me right n...thanks, that article is very useful for me right now. also in your exterior wall design referred as best, where does the condensation occur? i am interested in this as i might use it. from what i remember from school the best way to avoid condensation in wall was to place layer with highest R-value closest to exterior. i remember placing rigid on exterior side of cavity alone would push condensation outside and than when adding batts it was really counter productive as it would pull condensation plane inside the wall cavity. not exactly sure if i remember this correct. but seeing another high R-value layer on interior side just got me interested how it works.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-38363189.post-89838220448703159262012-01-10T08:57:21.494-05:002012-01-10T08:57:21.494-05:00TJI's are the worst to seal around, because th...TJI's are the worst to seal around, because they have twice as many corners as an ordinary joist. I don't have any great advice for you here. Lots of tape, lots of patience. Spend some time looking at the Swedish Platform Framing article linked at the top of the right sidebar. The best strategy is keeping the joist ends in-board of the vapor retarder.lavarderahttps://www.blogger.com/profile/07241073948874188058noreply@blogger.comtag:blogger.com,1999:blog-38363189.post-67673400388540329532012-01-10T01:01:07.650-05:002012-01-10T01:01:07.650-05:00so right now here in US what is the best way to se...so right now here in US what is the best way to seal vapor barrier around tjis on two story structure? i am thinking polyisocyanurate boards cut to fit between joists and than just foam primeter of each board, and bring wall poly and seal against them. sounds quite time consuming though. i assume my 1st floor ceiling doesnt need vapor barrier since both floors are heated.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-38363189.post-63379329700612287812011-09-23T11:31:34.147-04:002011-09-23T11:31:34.147-04:00good god that sounds BRILLIANT!

VERY interesting product and approach.Robhttps://www.blogger.com/profile/02755641385168532842noreply@blogger.comtag:blogger.com,1999:blog-38363189.post-36728323516404513162011-09-23T11:25:21.631-04:002011-09-23T11:25:21.631-04:00Rob, I think they buy these folded pieces pre-fold...Rob, I think they buy these folded pieces pre-folded for this purpose, however I think its a third party company that does the folding part using the vapor barrier sheet from Isover. Isover makes the sheet material, but not the pre-folded product, so somebody else makes the folded "accessory" as an added value product, and again something made "at home". Isover is sort of like a Certainteed entity in Europe, a big insulation maker. <br /><br />So the wall panels come from the factory with the vapor barrier already installed, and a flap extending past the top that you can tape to. When the joists are set these folded pieces can go around the joists and everything taped tight before the deck goes down. I think in practice the deck is already in place in the center of the room, and a margin is left around the perimeter to complete this work, run wiring, and radiant heating tubes before the last of the deck goes down.lavarderahttps://www.blogger.com/profile/07241073948874188058noreply@blogger.comtag:blogger.com,1999:blog-38363189.post-48614039265046263622011-09-23T11:16:01.667-04:002011-09-23T11:16:01.667-04:00that's brilliantly simple looking...
