Hi gang,

As I sit and ponder the meaning of life and SIPs I still have to wonder a bit given their premium price. Not that having such good insulation value is a bad thing, but has anyone ever given thought to a metal studded exterior system like commercial buildings?

Slap up some drywall on the exterior of the TF with just enough screws to hold it into place. Add some vapor barrier. Then add the metal stud system outside of the drywall. Easy to work with and cost is better than lumber.

Add wiring, insulate, add exterior sheeting if required. Inside of house screw drywall to metal studs etc.

Would be cheaper than SIPs and wood framing, yet able to go up quick due to the light weight of the materials.

Thoughts?
