The best window for your home depends on ventilation needs, orientation, energy performance, building code requirements, and installation details. This guide explains the most common window styles — and how we help Colorado homeowners select the right option for their specific home, not a manufacturer sales quota.
What Most Window Companies Don’t Explain About Window Styles
Window styles are often presented like a catalog — pick the one that looks nice and move on. But in reality, the right choice depends on:
- Home orientation & sun exposure
- Ventilation patterns
- Egress & tempered glass requirements
- Framing condition & siding interface
- Wind exposure & WUI zones
- Glass package performance (U-factor / SHGC)
At Northern Lights Exteriors, we don’t start with brand incentives. We start with how the window will function in your home….and what pain points are you trying to solve for your upcoming window project investment.

Common Window Styles We Install
Double Hung Windows
Bedrooms and traditional homes.
Excellent for meeting bedroom egress requirements while maintaining a classic look.
Advisor note: A strong “safe pick” when you want familiar aesthetics with easy ventilation.
Casement Windows
Modern homes and homeowners wanting maximum energy performance.
Strong seal against wind; ideal for higher elevation areas.
Advisor note: Great when comfort is priority #1—tight seal, clean lines, modern feel.
Sliding Windows
Wider openings and contemporary layouts.
Minimal exterior projection — good near patios and walkways.
Advisor note: Ideal where you want wide ventilation without outward swing clearance.
Picture Windows
Mountain views and maximizing light.
Pair with operable windows nearby for ventilation.
Advisor note: Perfect for “view moments”—we often design these as anchors with operables flanking.
Bay & Bow Windows
Expanding interior feel and architectural impact.
Requires structural evaluation and careful flashing integration.
Advisor note: High-impact upgrade—best when planned as part of an intentional elevation design.
Awning Windows
Bathrooms and lower openings.
Can remain open during light rain.
Advisor note: Great for privacy + ventilation—especially when paired above counters or tubs.
Specialty Windows
Architectural statement homes and unique openings.
Custom shapes should be specified with the right glass package for sun/UV orientation.
Advisor note: These are where design shines—arches, triangles, trapezoids, and custom geometry.
What Do Different Window Styles Cost?
Online window calculators rarely account for installation complexity, framing condition, or glass performance. We built a transparent guide explaining how real window pricing works in Colorado.
