| Scope | Estimated range |
|---|---|
| Vinyl (standard) | $240 – $620 |
| Vinyl (premium) | $400 – $950 |
| Aluminum (standard) | $300 – $760 |
| Aluminum (thermally broken) | $520 – $1,100 |
| 8-window delta | $500 – $1,800 |
Ranges reflect installed cost including materials and labor for typical residential work. The low end of each range corresponds to a basic vinyl configuration; the high end reflects premium frames, upgraded glazing, and larger units. Last reviewed 2026-11-12.
Vinyl is a poor conductor compared with aluminum, and aluminum frames need a thermal break to avoid condensing and losing heat at the frame. Without that break, an aluminum frame can be the weakest part of an otherwise good window.
Aluminum carries far more structural load per unit of frame width, so it can span larger openings with thinner sightlines. For a big picture window or a storefront-style opening, vinyl simply cannot match the proportions.
Salt air and intense UV degrade vinyl over time, and dark vinyl in a hot climate can distort. In coastal and desert markets aluminum, often with a thermally broken frame, is the more durable choice despite the thermal penalty.
Untreated aluminum outlasts vinyl in harsh sun and salt; vinyl can chalk, fade, and in dark colors distort under sustained heat. In normal inland climates both routinely last 20-25 years with vinyl requiring less maintenance.
Yes, with a thermal break and good glazing. The break separates the inner and outer frame so the frame does not conduct heat through. Without one, aluminum performance lags vinyl significantly.
Generally yes, by $60-180 per opening for comparable glazing. On large or custom openings the gap can close or reverse because aluminum's strength allows fewer, larger units.
