Alberta conditions
Does Alberta’s dry air and chinook weather affect wall art?
No, and that is the main practical reason metal suits this province. Alberta winters run very dry indoors, and a chinook can swing the temperature twenty degrees in a day. Canvas and paper react to that by tightening, slackening and rippling. An aluminium panel does not move.
This is the part people find out the hard way. A stretched canvas is fabric under tension on a wooden frame, and both react to moisture in the air. Through an Alberta winter, with the furnace running and indoor humidity dropping into the teens, that fabric tightens. When a chinook pushes the temperature up twenty degrees in an afternoon, it moves again.
Over a few seasons that shows up as a ripple across the surface or a visible sag at the corners. Aluminium does not care. There is no fabric to tension, no wooden stretcher to twist, and no paper fibre to absorb anything.
Basements and bonus rooms
Finished basements swing between damp in summer and very dry in winter. A sealed panel handles both without warping.
Garages and shops
Unheated and freeze-thawing all winter. Metal is the only thing we make that belongs out there.
