Buying SIP panels directly from Suppliers in China.

[Raju Balakrishnan]

I am in planning phase for a cottage style small resorts in California. Planning to use OSB SIP building for small units of size 900 sq: ft, primarily for fast build and energy efficiency. Sourcing directly from China is cheaper, though more complex. But  effort is worth it as once the first unit is done it will be a copy-paste.  This will be like a normal site built home on foundation (not modular) going through regular inspections and permits, but using SIPs instead of sticks. 

1. Any experience/thought on buying directly from China, (The panes seems compliant with IRC, etc and probably can make sure that they are complient with Californa Residential Code  etc also)?

2. OSB vs Other type of SIP panels (fiber/steel), pros and cos?

I'm sure you didn't make a post to debate the pros/cons of SIP panels, but there is a reason that SIPs/ICF construction is less than 1% of starts in the US.  The reason is that the energy savings aren't worth the additional costs.  Especially the additional costs by electrical, HVAC and plumbing.  Most of the trades aren't used to working with SIPs and will charge additional.

The sales people for both SIPs and ICFs will tout the labor savings, but they simply don't exists.  Otherwise, builders who build 100s or 1000s of homes per year (and work really hard to save $100 on any one trade) would start building with them.

I'm sure many similar arguments can be made for any revulutionary product (electric cars) but SIPs and ICFs have been around for decades without gaining any traction.
