Windows That Save Energy and Survive Colorado
Old single-pane windows can cost a Colorado homeowner $400-$800 per year in lost heating and cooling. Replacement windows pay for themselves over time, especially given how dramatically Colorado temperatures swing across seasons.
Beyond energy savings, modern replacement windows improve home comfort (no more cold drafts in winter), reduce noise, and increase resale value. They also typically qualify for insurance coverage when storm damage causes glass breakage or frame damage.
Window Types We Install
- Vinyl windows — cost-effective, energy-efficient, low maintenance; standard choice for most Colorado replacements
- Fiberglass windows — premium option with better thermal performance and longer lifespan than vinyl
- Wood-clad windows — wood interior, vinyl or aluminum exterior; for homes prioritizing interior aesthetics
- Aluminum windows — limited use in Colorado due to cold-weather thermal performance issues, but appropriate for some commercial applications
Energy Efficiency for Colorado Climate
Window energy ratings matter differently in Colorado than in other climates. We pay attention to:
- U-Factor — measures heat loss; lower is better; we recommend 0.30 or below for Colorado
- Solar Heat Gain Coefficient (SHGC) — for Colorado’s mix of cold winters and hot summers, balanced SHGC values around 0.30-0.40 work well
- Air Leakage — lower is better; quality installation is as important as the window itself
- Energy Star certification — confirms minimum energy performance standards
Installation: Where Windows Actually Fail
The window itself is rarely the failure point. Almost all window problems trace back to installation:
- Improper flashing causes water intrusion behind the wall
- Inadequate insulation around the rough opening creates cold spots and condensation
- Skipping the sill pan flashing leaves the window vulnerable to driven rain
- Using exterior-only caulk without backing creates failure points within 5 years
Our window installations include proper flashing, sealed insulation around the opening, sill pan flashing, and backed exterior sealant. Trim work — both interior and exterior — is included so the project is genuinely complete.
Storm Damage Window Replacement
Hail breaks glass. Wind drives debris into windows. Tree branches crash through them. After major storms, window damage is often part of the broader insurance claim. We document any window damage during our exterior inspection and include it in the claim documentation we send to your adjuster.
