Colorado homes face a challenge that most climates don’t: dramatic temperature swings, snow-packed winters, high UV exposure, and dry summer heat. Your windows aren’t just design features — they’re critical to energy efficiency, comfort, and curb appeal. That’s why choosing the right window type matters.
At Gravina’s Window Center of Littleton® we’ve helped thousands of homeowners find the perfect windows for Colorado’s climate and code. As the oldest Infinity from Marvin® dealer in the state — and Denver’s most trusted name in window replacement — we know what works, what lasts, and what to avoid.
This guide breaks down the top window styles — from casement to bay, double hung to sliding — so you can compare features, materials, and performance before replacing your windows.
Top Window Types for Colorado Homes — Backed by 50+ Years of Local Expertise
If you’re short on time, start here. These are the most reliable window choices for Colorado’s climate, based on thousands of successful installations by Gravina’s Window Center of Littleton®.
- Best for Energy Efficiency: Fiberglass Casement or Picture Windows
- Best for Ventilation: Double Hung or Awning Windows
- Best View & Natural Light: Bay and Bow Windows
- Lowest Maintenance: Infinity from Marvin® Fiberglass
Why Matching Window Type Matters in Replacement
- Continuity: Preserve the original design of your home by matching window types. It helps maintain curb appeal and architectural integrity.
- HOA Approval: Homeowners Associations often require you to stick with the original window style to maintain neighborhood uniformity.
- Building Code: Want to swap a casement for a double hung? Make sure it’s not in a bedroom—egress codes may require full clearance for fire safety.
Choosing the Right Window Material
- Fiberglass Windows: Strong, durable, and energy-efficient—perfect for Colorado’s extreme temperatures. Infinity from Marvin® is our top choice, and Gravina’s Window Center of Littleton® is proud to be the oldest Infinity dealer in the state.
- Vinyl Windows: Affordable and low-maintenance, but may warp or fade over time. Not ideal for high-altitude UV exposure.

Frequently Asked Questions
What type of window is best for Colorado’s climate?
Because Colorado experiences large temperature swings, intense sun, snow, and high winds, the best window type is one that offers superior insulation and structural strength. We recommend fiberglass windows—especially Infinity from Marvin®, known for their durability and thermal performance. Casement, picture, and double hung windows with Low-E glass are also excellent for balancing airflow, comfort, and energy efficiency.
