[QUOTE="NightShade, post: 3230082, member: 29706"] Foam and as thick as possible. Another one that works pretty well is rockwool. It is often used in conjunction with a layer of spray foam in new and remodel construction. Foam in and of itself can be flammable or noxious when flame is applied. It is something to think about and ask questions on as fire is always a possibility. If you REALLY want to save money you should look at something like staggered studs, think of it this way, even a 2X10 will conduct some heat through it. If you make your wall 8 inches thick but use 2X4's in a staggered pattern you can prevent the heat transfer. Another option is to insulate the whole outside, instead of putting sheathing on and then insulating between the studs you take and put thick foam panels on the whole outside of the building. There are video's on youtube that show it done at a place in Texas, you go inside the house and you see the studs and the sheathing but a flir camera shows no heat loss. Another thing to think about is using a geothermal heat pump. Basically instead of having a coil where the transfer is done to air you have a big line either ran deep into the ground multiple times the same way a water well is drilled or you run a coil in the ground a few feet down and transfer the heat from the ground. The ground is always going to stay fairly stable so in the blistering 100 degree days your system has the same efficiency to cool as on a 75 degree day. Personally I would do a staggered stud build and then add two inch foam panels to the outside. Now I know that a house needs to breathe, however do you want it breathing damp hot air from the outside or climate controlled air from the inside.... Seal the outside up completely make sure all the foam joints are sealed and any edges are sealed, rockwool the exterior walls and any interior area's you want to stay quiet. Geothermal heat pump and a couple grid tie inverters and solar panels on the roof. The extra you spend will easily end up paying for itself before the house is paid off. [/QUOTE]
