How do I price an insulated glass unit accurately?

The Insulated Glass Unit Cost Calculator combines lite cost from the Coated Glass Cost Calculator, spacer material, sealant usage and the IGU Gas Fill Cost for argon or krypton. Add glazing labor and assembly time. A dual-pane low-E argon unit typically stacks glass, spacer, primary and secondary seal, and gas fill into a per-unit cost you can carry straight into Construction Product Margin Dollars.

How is glass cut yield calculated and why does it matter?

The Glass Cut Yield Calculator divides usable lite area by total sheet area to show the percentage converted to product versus offcut. On stock sheets, yield often runs 75 to 88 percent depending on nesting and size mix. Every point of lost yield adds directly to Fenestration Scrap Cost, so optimizing cut patterns on high-value coated glass protects margin the fastest.

What should I charge as a customization premium for non-standard windows?

The Order Customization Premium Calculator captures extra setup, slower line speed, lower glass yield on odd sizes and added handling versus a standard SKU. It converts those into a dollar uplift per unit. Custom sizes that drop cut yield and force a line changeover often justify a 15 to 30 percent premium to hold the same Construction Product Margin Dollars as standard production.

How do I set warranty reserve for sealed insulated glass units?

The Fenestration Warranty Reserve Calculator multiplies expected seal failure or fogging rate over the warranty term by replacement and reglazing cost per unit. Because IGU warranties often run 10 to 20 years, even a 1 percent lifetime failure rate at a high reglaze cost accumulates. Reserving that per unit shipped keeps long-tail seal failures from hitting future margin.

How do I find the throughput limit on a window line?

The Window Line Throughput Calculator converts available line minutes and cycle time per unit into units per shift, and the Production Takt Time Calculator sets the pace needed to meet the order. If demand takt is 90 seconds but glazing takes 110 seconds, glazing caps output. Compare station times against takt to find and staff the bottleneck before it delays shipments.

How much does door rework cost when hardware or fit fails inspection?

The Door Rework Cost Calculator adds rework labor minutes at the loaded rate to scrapped hardware and material from the Door Hardware Cost Calculator, plus lost line time. A door pulled for misaligned hardware can carry rework labor plus replaced hinges and strikes. Tracking this against defect volume shows whether upstream fit-up fixes pay back faster than reworking at end of line.
