Aluminum window cut list: frame and sash profiles
What it does and how it is worked out
Type the cuts of your aluminum window and the page lays them out on the fewest bars, with what is left of each one. Free, in the browser and on a phone. The list below is an example, the frames of four sliding windows, 60 × 48 in: 16 pieces on 4 bars of 240 in, 97 % of the bar used. Clear it and put in your own cuts.

The example of this page, worked out
The list the page opens with is an example, not anybody's order: the frames of four sliding windows, 60 × 48 in. Every length comes from the outside sizes of the job, and the figures are the optimiser's own, worked out by the same code as the tool above, on bars of 240 in with a 0.125 in cut and 0.5 in trimmed off each end.
| What the optimiser answers | Figure |
|---|---|
| Bars to buy | 4 |
| Pieces | 16 |
| Bar used | 97.2 % |
| Waste: blade, trim and short ends | 2.8 % |
| Offcuts worth keeping, 12 in or more | 2 · 5.8 ft |

What to watch: aluminum window
- Mitres are measured on the long point. A frame mitred at 45° has four parts as long as its outside width and height: the mitre is cut inside that length. Two mitres back to back share one cut only if the profile is symmetrical; otherwise count a blade's width for each.
- Each profile is its own list. Frame and sash are different profiles, each bought in its own bars: this page opens on the frames, and the sashes of the same windows are one of its templates. Their sizes come from the frame by the deductions of your system; the ones here are an example.
- The bar you buy. Profiles come in set lengths: change the bar to yours, and the offcuts worth keeping follow.
- Your bar, your blade, your trim. The example is on bars of 240 in with a 0.125 in cut and 0.5 in trimmed off each end. Set the bar your supplier sells and the width of your blade: the plan is worked out again as you type, and so is what is worth keeping (12 in or more here).
