Your windows are
costing you every Arizona summer.
Standard aluminum windows weren't designed for 115°F heat. Take our 4-step assessment and see exactly how your current windows compare — and what it means for your energy bills.
Find out where your windows stand.
Answer four quick questions about your home and current windows. We'll show you a personalized performance report — no email required.
What type of windows do you currently have?
Not sure? Single-pane feels hot to the touch in summer. Double-pane aluminum is the most common in Arizona homes built after 1990.

European uPVC vs. standard aluminum.
Every spec that matters for Arizona homeowners — with no marketing spin.
| Specification | Luft European uPVC | Single-pane aluminum |
|---|---|---|
| U-Factor (heat transfer) | 0.17 (triple-pane) — best available | 0.60–0.79 typical — far above ENERGY STAR limit |
| SHGC (solar heat gain) | 0.19 with Low-E — blocks 80%+ of solar heat | 0.55–0.68 clear glass — lets most of the Arizona sun in |
| Air leakage | 0.01 cfm/ft² — near airtight | 0.15–0.30+ cfm/ft² — at or above ENERGY STAR limit |
| Frame thermal bridging | None — 6-chamber uPVC insulates continuously | Severe — metal conducts heat directly in, frames reach 150°F+ |
| Sound reduction (STC) | STC 42+ — noticeably quieter indoors | STC 25–30 — road and neighborhood noise passes through |
| UV blocking | Up to 99% — protects floors, furniture, art | Minimal without Low-E — fading occurs within a few years |
| Lifespan in Arizona | 30+ years — uPVC dimensionally stable in extreme UV and heat | 15–25 years — seals fail, frames oxidize, thermal cycling wears joints |
| Warranty | 20 yr frames / 15 yr hardware / up to 10 yr glass | Typically 5–10 yr limited |
| ENERGY STAR Southern Zone | Exceeds all thresholds | Most standard aluminum units do not qualify |
