|---|---|---|---|
| U-Factor | 1.0–1.2 | 0.25–0.30 | 0.15–0.20 |
| Cost per Window | $100–$200 | $300–$500 | $450–$750 |
| Energy Savings | Baseline | 25–40% better | 45–60% better |

Vinyl is the most popular for cost-effectiveness ($250-600/window). Fiberglass is strongest and most durable ($400-1,000). Wood offers classic aesthetics ($350-800). Aluminum is cheapest but conducts heat ($200-500).
| Frame Material | Cost/Window | Lifespan | Maintenance |
|---|---|---|---|
| Vinyl | $250–$600 | 20–40 years | Very low |
| Fiberglass | $400–$1,000 | 40–50 years | Low |
| Wood | $350–$800 | 30+ years | High (repaint every 3–5yr) |
| Aluminum | $200–$500 | 20–30 years | Low |
| Composite | $500–$1,200 | 30–40 years | Low |
