I love this forum and have gained so much knowledge and insight on projects. I always feel that the advice and opinions are true and accurate and not from contractors who are trying to sell you more their product to jack up the price. I am doing everything myself. So I guess this is more of advice and what would you do?
I am trying to figure out the best/most cost effective way to insulate a remodel project i'm doing. The major issue is that all the framing is 2X6's. There are a number of options and possibilites to go with, and I am stuck as to what to do. Bascially, its a second floor redo with a shed dormer on the back and a kneewall running the lenght of the front. I have done so much research and now just need some advice. I plan to at the "minimum" use spray foam from the lenght of the shed dormer down to the kneewall to avoid venting and also achieve a higher R-value. I have gotten price to spray the whole roof line (both sides of the kneewall) as well as the exterior walls, but it is very costly and we aren't planning on staying in the house to long. But it is a lot easier because they come in and in a day the insulation is done. I do not know if it worth investing that much money when I will not be there long term we are moving in a few years. The kneewall space we want to use for storage. If I do not spray the entire roofline, I would have to most likely build up the kneewall floor to allow for more blown in. Much much dense blown in can you get in say 8"? for the knee wall I would either use fiberglass or blow inand then can i put foam board on the back side of the kneewall to make it more effiecent?
Is it pointless to do the whole roofline in foam, and then do the exterior walls in fiberglass/blown in? Am I losing alot of the effiecency of the foam?
Basically, I can do this a few ways or after I built everything up and get the other insulation in place would it have not been that far off to just spray everything?
1) spray foam everything walls/roof etc- Costly and we are not staying to long in the house to see the rewards.
2) spray down to the kneewall, insulate kneewall and inside kneewall floor with fiberglass/blow in - more work, would have to build up kneewall floor to accomadate more material and put down plywood for storage.
3) Spray entire roofline and use fiberglass/blown in on the exterior walls. Kneewall won't need to be insulated?
What are some ideas and opinion? Really need help on this one. IS the dense blown in expensive?
