My neighbor is having his wood shingles removed on his 1920’s house, and installing new cedar shingles, prefinished with bleaching oil. He has asked me if it is okay to have cellulose blown-in insulation put in while they are working on the house, given that the only work being done to the house is from the exterior. He is worried about condensation in the new insulation, as he will not have a vapor barrier in the walls. What do you think?

Hi, Paul. Your friend's situation is very analogous to one i have. I'm reassured after a lot of reading and talking to folks to rent a blower and blow cels in the enclosed bays, without a vapor barrier. Go to the HVAC folder and find "To VB or Not to VB" in the thread list--should be quite helpful.
The number is 980.1, if that helps. (Is there anyone out there who can tell me how to link to it???)

I went to the Show Discussion frame and click on the Engery, Heating and Insulation folder. That opens it up to a show all mode for that folder. Then I scrolled down and found the thread.
Right clicked on it (with Netscape) and copied link. Then just pasted the link here and it shows automatically;

Bill, thanks very much; that should have been obvious to me, right? I guess after two weeks of Prospero i'd just come to expect a complicated solution involving the advanced search page, three log-in attempts, and an email to sysops.
Paul,
If he's still concerned, one possibility is repainting inside{still a lot of work, but no ripping apart walls} with one of the vapor barrier paints that are available. This puts a vapor barrier right at the warmest part of the wall.
Thanks for the replies. First time using the site, though I've been reading the excerpts in the magazine for awhile.
