A comparison of materials for building the frame of a tiny house on wheels.

Structural insulated panels + skim coat Wood framing + spray foam insulation + wooden panels Steel framing + spray foam + wooden panels
Avg. weight
Price range $10.00 – $12.00/square foot
The good
  • Structures use roughly half the energy of new stick-built homes
  • Make it easier to build tight
  • Are up to 300% stronger than stick-frame
  • Go up faster than insulated stud frames
  • Super tight insulation
The bad
  • Toxic chemicals in the insulation
