<\/a><\/p>\nAfter we got everything up, it was time for spray foam. \u00a0We paid a company to do this part. \u00a0It took them half a day and they needed a large box truck to carry their machine. \u00a0While they were at it, we also had them do the closet \/ former bathroom \/ future office \/ deck entryway.<\/p>\n
<\/a>Spray foam (yellow) in all its glory<\/p><\/div>\n
<\/a>More detail in the corner. Walls are only about 1″ thick, but they act as a vapor barrier and are likely way more effective than cramming in styrofoam sheets which is what is likely behind the drywall that we left in place.<\/p><\/div>\n
On the 3rd floor, we tried our best, without replacing the whole roof, to meet the minimum\u00a0recommended R value for a roof in our area\u00a0of R-38<\/a>.<\/p>\n The total R value for our roof is between R-33.36 \u00a0and R-38.16. \u00a0This depends on the thickness of the foam between the joists.<\/p>\n When they sprayed it, they were careful to not make it stick up higher than the joists so it would be easy to install drywall. \u00a0They were a bit too conservative in my view sometimes leaving over an inch of cup between joists. \u00a0Luckily, even the sealed air gap itself has a value of R-1.<\/p>\n Pretty good on paper. \u00a0Pretty effective in the real world. \u00a0With just the work lights on, the top floor can get HOT enough that we needed to open windows. \u00a0Condensation shouldn’t be an issue inside the ceilings, but it does occur on the windows and maybe even in the walls.<\/p>\n The guest room doesnt have the 2″ pink sheets as we decided that ceiling height for this small area was more important than R value. \u00a0There will be some interesting \u00a0transition from the stair way to the 3rd floor ceiling here, but we’ve got it figured out. \u00a0I’m not too worried. \u00a0For over 100 years people lived in this house and I can’t imagine it had\u00a0more than R-10 and it had visible air leaks (I mean I could see the harbor looking through them).<\/p>\n Iris helping me to lift one of these heeaaavvvyyy sheets while dad does something likely more significant in the background.<\/p><\/div>\n After all the insulation was up, we added the drywall. \u00a0On the 3rd floor there was lots of cutting as nothing at all is square or level. \u00a0We shimmed with wood and still found some spots that would push in. \u00a0We did some experimenting and figured out that we could punch a hole in the drywall and spray in some Great Stuff foam which would act as a shim after the sheet was already up.<\/p>\n Walls are up, still need to finish the small pieces above where the drop ceiling used to be. \u00a0Dad took care of all that little stuff while I worked on finishing things downstairs. \u00a0Strangely the old man seems to enjoy this stuff.<\/p><\/div>\n The previous owners only did drywall up to the drop ceiling so we had to do the rest up to the top. \u00a0Dad is intent on blending it in with spackle.<\/p>\n Starting to Spackle. \u00a0Also, we seem to have developed a black spot in the middle of all our pictures. \u00a0Construction and digital cameras don’t mix.<\/p><\/div>\n\n
