I designed and had a company called "Murus" engineer and build our SIP home in their factory. The construction pace was cool to see how fast it went together. This was 10 years ago almost exact. The insulation value is excellent and noticeable - especially our summer AC bills. The downside was the construction process was difficult because we had to deal with two builders - the GC and the SIP builder. This led to misunderstandings as to who was responsible for what - like insulating the gaps between the windows and the SIPs for example! The electrician also had difficulty grasping how to run electrical in SIPs.

I also think that the acoustic attenuation is not as great with SIPs versus loose insulation.

I would still do SIPs or maybe concrete if I had it to do over again. I would also find an architect and builder that can handle everything instead of splitting the load.
