We've been installing Tiny Arch shelter for years, and it has a very gentle architectural shape from the sky view, which actually changes with the air temperature.
So this particular shelter is in Central Otago and as such would have a very big temperature range from probably +35°C down to -10°C.
That is no problem for Tiny Arch because it automatically changes itself depending on the temperature.
(Other shelter systems are reliant on excessive fasteners/tension, and problematic rubber to deal with the twin challenges of thermal expansion and water-proofing)
