Dow Styrofoam SIS(Structural Insulated Sheating)
Looking for anyone who has used this product. I'm told it just came out this year and is a 3in1 product that would replace traditional osb, rigid foam board and housewrap in one application. I've just started building my house in NE Georgia and was planning on using osb and house wrap only. My exterior framing is 2X6 on 16" centers and 10 foot walls. I intend to use damp sprayed cellulose between the studs giving me a R-21.
The price of this product is roughly 4 times the price of OSB. The 1/2 inch sheet gives a R-3 value.
Would this product be cost effective in a hot summer mild to cool winter climate?
