Denver (Mile High City, 5,280 ft elevation) has a semi-arid continental climate with cold winters featuring frequent snow, warm dry summers, and abundant sunshine (300+ sunny days/year). The city sits in the hail capital of the US, driving high impact-rated roofing demand. Quality Low-E or triple-pane systems reduce heating/cooling costs 15-30% versus original single-pane windows; they also improve sound dampening, reduce UV fading of furniture and floors, and add measurable resale value.
A typical Denver window replacement runs $6,700-$14,900 for 15 windows in 2026. $355-$835/window, Low-E required, Energy Star Northern/Mountain zone. Vinyl Low-E is the Denver workhorse for most homes; premium wood/composite suits historic homes; fiberglass offers the best dimensional stability in extreme temperature swings.
