Hello Sue good to see you again! That looks like a wild mess but I bet it makes a big difference. We had a similar insulation job done and the difference is surprising. Our attic has 3' of pink closed cell foam already but I'd be interested in how the rafters do with spray foam. Keep us updated would ya? This is interesting.
Thanks, Pete, I'll do that. It will especially be interesting once the cold weather comes; I don't think there will be a drafting issue, but I want to make sure there is no humidity/condensation problems. From what I have read, that could happen in a) cooler climate and b) attics that are not "open", i.e. used as living spaces with walls covering the foam, and no vapor barrier. But this stuff is a relatively new process, so I guess I am one of the guinea pigs p.s.--I have REALLY enjoyed your pallet projects!!
Thanks Sue! I am a tight budgeter and pallets are free sooo.. I'm glad you joined the club! We did have a small condensation issue in our bathroom after a shower but that was easily corrected by installing a bathroom vent instead of just using a window fan. It was due to a tight bathroom which we never had before the foam was sprayed in.
Hey Sue, I'm sure this thread has made you a believer in this forum! Some good information here and some great guys to give it. Best part is you should be a lot more comfortable in your home summer and winter.
Thanks! They do seem to make you feel very welcome here! Now if we could just get the e-mail alerts to work...
Firebroad, or should I say Sue, I too am concerned about the apparent lack of ventilation from the soffit area to the ridge area of your attic, but I'm sure your foam installer has been down that road before. It is very important for the attic to be properly ventilated. Now then, great job on the foam; I sure wish we could have it done at this house. Unfortunately, the construction of the house's walls have what is referred to as a "mid-wall". Thats where there is an actual wall built inside of the stud wall. leaves about 1 1/2" of space for each side of the midwall to the outside and midwall to the inside walls. It just isn't large enough for a nozzle to get into. It was sort of the norm for building way back many years ago. Kind of using the dead air space approach for insulation...
Yeah, I know the type, we had them in the house I grew up in. If you crack away the plaster, there is a bunch of slats running across. Actually, the icynene foam injection can be used for set up, as they drill holes in the outside of the house(either under the siding, or through the mortar joints, then patch them up) and inject the foam. It spreads, but does not expand in an "explosive" manner, as other foams do. I am calling BS on the temperature differential promised with this job. I spoke to the owner of the company who said that the temp of the attic will NOT be withing a 3-4 degree difference UNLESS there is a vent from the heat pump up there. But he still assures me that I will save dramatically on my heat/cooling. I have no doubt that it will be warmer up there in the winter, and that will be to my advantage--but I am not so sure I want to pay to have a grille installed just to pump air conditioning into an unoccupied attic. Do I think I will save money? Probably, especially in the winter.
