Hi Shaun - you didn't say whether your frame is on the foundation or just being cut. If the foundation is still fully exposed, you could bolt angle iron (of appropriate size to carry the SIPs) to the foundation. Depending on what type of foundation you have, you may be still be able to do this even with the frame in place. With a poured concrete foundation, this is a simple matter. Another, albeit somewhat more complex, solution is to form a concrete ledger attached to your existing foundation to create the required profile to support the SIPs. This requires a secure union between the ledger and the present foundation. There are several ways to accomplish this. A local concrete contractor could give you the best solution for your locale. Good luck with your project. JEK
