    Ilona, As many of my articles point out, insulating an old Cape is challenging. By far the best approach is to install an adequately thick layer of rigid foam above the roof sheathing -- ...

    Thank you, Martin. Obviously, this the least desired possibility. My understanding was that there simply was no way to create a continuous air channel between the attics and the peak of the roof. ...

    Ilona, I'm assuming that you have been visiting GBA long enough to find the articles that are relevant to your problem, but in case you haven't, here are some links:

    Just took a tour of new homes in the Anchorage, Alaska area yesterday. Out of 6 or so homes visited, only one had an hrv and that one had fresh air venting into the bathrooms and stale air ...

    Ilona, One other point: If the leak is near an area of roof repair -- the area where the chimney was removed and new sheathing was patched in -- it is conceivable the the stains you noticed are ...

    Ilona, I'm sorry to hear about your problems. If you paid a contractor for the insulation work, the first step is to call the contractor and insist on a remedy for your moisture problem. The ...

    1.I had the insulation contractor do the job. He insulated the sloped rafter bays with the blown-in densely packed cellulose. I don't have any way to know how many inches he was able to pack in ...

    Ilona, I'm not sure I understand, but I'll try to summarize. Do I understand correctly that: 1. You insulated the sloped rafter bays with 5.5 inches or 6 inches of dense-packed cellulose, ...

    Sorry, the first time poster mess up! My name is Ilona. Facing too many connandrums with our 11/2 story house. I will try to be concise but frustration does get to me. After much research and ...

    Michael, Q. "Would we be better off removing the insulation if we're going to remove a few boards to inspect anyway?" A. No. If you are talking about cellulose insulation between your studs, ...

    MN, First of all, can you tell us your name? I think you tried to cram too many words into the title, and some of your words got cut off. You should post a comment with the missing information ...

    You correctly spotted that even the very top of the first page has double-digit percentages errors, starting with "Window U-Value: 0.3" ...(= code minimum) when your worst windows are ...

    I'm still researching the best solution for our house so I'm visiting this topic with one more question. I'm concerned what the vinyl siding on our house is hiding so I definitely want to remove ...

    There is a variant of project fatigue that affects builders own houses. A mixture of wanting to constantly renovate, not feeling like doing the same work at home in your spare time that you do all ...

    Elden, thanks for your article and the subject conclusion. I must admit, I only skimmed the article, but I certainly did not miss your conclusion on passive solar. It has been a long time ...

    Pent-roof it is then, thanks for the correction! Also, I got my torque units wrong (thanks Michael), it should have been ft-lbs, not lbs/ft. Beyond that though, I'm not following your ...
