    I'm going to be building a new summer home on the shore in New England and was thinking of going with a high velocity heating/cooling system. Is there a lot of experience out there with them to say...

    No cans, etc...ceiling upstairs is sealed with blown in foam. BUT Icynene now says that it needs a vapor retarder and my builder just primed the ceilings (cheapskate and I didn't notice the...

    well got the cellulose...still a bit too warm. Even with a gable fan running all night it only got down to 6 degrees warmer than the outside temp when I got up at 6am today. I guess the R6 (or 8 I...

    If you are in NE, who did your blown in cellulose? Anyone near Boston? Not a lot of contractors use cellulose it seems.

    I don't remember how tight the house was but the guys from Building Science who know it all tested it with their seal of approval. The ducts haven't been tested since being replaced though. I will...

    they do have styrofoam baffles but foam has seeped in and blocked quite a few, mostly those over the kneewall since it was such a long run.

    sounds like the same song and dance - "you only needed x inches" not the 9 inches to achieve R30 code...Icynene is definitely >1.7/inch though...I guess the contractor didn't use Icynene? Was there...

    Bathroom vents being used don't seem to affect the humidity up there so I think they are tight. We had a duct blaster done on the original ductwork that was here - but we replaced it and they...

    we actually had a blower door test on the house at one point and it was tight by building science standards, so I don't think there is a void that was missed...i don't get any negative pressure...

    Aprilaire suggested the return as there was no area in the supply duct that would allow for a straight run of 36" before elbows, dampers, etc. to allow for proper dispersion. Unless I put it on 1/3...

    Its a TWE037. Not sure what we have outside now but for heat season it doesn't matter as we use an aquacoil hydroair for heating. Its set for 350CFM now on the dips but that is what it blows at...
