Alberta's climate is continental extreme - very cold winters and dry, often hot summers. uPVC in this environment cycles through a wider thermal range than in coastal or Eastern Canadian climates. Frame corner welds and co-extruded gaskets experience more cumulative stress here. Edmonton's high sunshine hours combine UV exposure with freeze-thaw cycling - a combination that accelerates UV stabiliser consumption in uPVC faster than either condition alone. Aluminium window systems in Edmonton require thermal break construction - standard aluminium without a thermal break creates a condensation highway between the cold exterior and the warm interior. On cleaning visits, the thermal break zone at the frame mid-section should not receive water.

This is how I clean Lux Windows and Glass windows. The tools and technique below come from 25 years of daily professional work on the glass. Every step has been tested on real installations and adapted specifically for Lux Windows and Glass systems.

• ✕Do not clean windows at below +5C - cleaning solutions freeze on frame and glass surfaces
• ✕Do not use abrasive pads or solvents on uPVC frames
• ✕Do not introduce water into the thermal break zone on aluminium commercial window profiles
• ✕Do not use acidic cleaners on powder-coated aluminium
• ✕Do not skip spring perimeter sealant inspection - Alberta freeze-thaw stresses sealant harder than most Canadian markets
