Looking for wall design to achieve R40 & Roof at R60
Hello. My name is Matt. I am reaching out to the community looking for imformation to design a wall that achieves R40 and roof assembly to get R60. I am working with my builder who is new to the Building Science group. We are in the intial design phase of the house. I would like to follow the 5/10/20/40/60 rule. I would also like to utilize the ZIP R product in the building process.
I would like to get some opinions on what the best makeup of the exterior walls to achieve R40 and roof at R60. I am open for any suggestions and pointers. I would also like to have material to present to my builder as he is very willing to work towards these goals. He wants to learn these basics so that he can roll them into his normal building process.
