What changes the price
- Size. Price follows the size of the opening, so a large picture-window storm costs more than a bathroom window.
- Model. The Premium 140 adds rigid vinyl tracks for a tighter seal and costs a little more than the Deluxe 240.
- Glass. Low-E, tempered, obscured and 3/16″ glass are options. Low-E adds the most energy savings.
- Delivery. Pick up free in Des Moines, or ship by truck freight anywhere we serve.
Custom size at big box store prices
Big-box stores stock a handful of sizes and leave you to make one fit. We build every window to the opening you measure.

How much does Low-E glass add?
On a 30 × 60 Deluxe 240, Low-E glass adds about $57.17. Larger windows add more because the price follows the glass area.
