"Key is this was done in warm weather. The back wall of the room was also uninsulated, but the lower portion was against the air-conditioned envelope of the home. The red area above was against the attic area, causing the increase in temperature."
Would you take your car to a local mechanic in a garage in his back yard to make repairs? That's the analogy your attempting to use. I doubt many would take their complex new technology vehicles to such a repair place. In fact, as cars…"
"This would be a great tool for the home I was auditing yesterday. Probably tell them to seal the ductwork and the like, insulate walls, crawlspace, etc. Same things I did. But, oh....by the way, would it tell them they had a life/safety situation in…"
"Not sure if I understand how sealing the flow of air through the soffit will reduce ice damns. The better approach would be to stop the heat loss through the attic floor with a better insulation job. Then provide proper ventilation so that the roof…"
Yes, that is condensation on the fiberglass batts, both those installed correctly, and those incorrectly. This was a brand new home. The contractor sprayed the crawlspace perimeter with closed cell polyurethane foam, put fiberglass in the floor…
"I'm a firm believer quality of installation is key to the effectiveness of any insulation. To say that one is better than another is not being fair to those that do a quality job of installing and giving credit to those that do poor…"
I don't believe you will find condensation on the wood sub-floor due to absorption. For example, take a block of wood and put it in your refrigerator along with a can of soda (or beer if you prefer). Take them out after a while and observe…"
