If you want a true four season they won't be lite weight. Close the door on a lite weight and on a four season (Northwood Product) and there is no comparison.
That's not true.
You can build heavy and 4 season - Northwoods Mfg
You can build light and 4 season - Lance
I'd put up my Lance 1685 TT against any Northwood Mfg product under any conditions. Just because something is made of wood doesn't make it more insulated.
As a matter of fact, 2 layers of Azdel offer more insulation properties than R-7 house insulation by far! Couple that with 2" block foam insulation and you've got insulation galore. Lance has dual pane windows, heated enclosed holding tanks and insulated gate valves, etc etc.
