Best Windows for Colorado
Recommended: Double-pane Low-E with argon fill (triple-pane for mountain locations)
Colorado's cold winters and high altitude make low U-factor windows valuable. Denver area: double-pane Low-E with argon. Mountain towns (Aspen, Vail): triple-pane. Hail is a risk — ask about impact-resistant options from manufacturers.
