- Lightweight - therefore higher payload
- Cannot leak heat or moisture - has no joints, bolts or rivets to leak, or metal to conduct heat
- No metal in body to fracture, twist or fail
- Clean, smooth and flat interior - no interior beams to intrude.
- Composite structure is a ‘single membrane’. Conventional alum/insulation/liner have differing expansion coefficients and allow sweating, leaking and pest infestation.
- Easy to repair composite construction.
- Lowest cost of ownership proven in the long-term.
- Longevity: in daily use for over 25 years.
