Choose glass for an opening

2 min read Updated 2026-08-21 WindoorERP 19.0

What this does

Sets what actually fills each opening — the specification that drives cost, weight, hardware and lead time more than any other choice in the design.

Steps

  1. 01
    Open the design from the quotation line.
  2. 02
    Select the panel you want to specify — each sash and each fixed light is its own panel.
  3. 03
    Choose the glass build: single, double glazed, laminated, toughened, or a combination.
  4. 04
    Set the thickness and any coating, tint or spacer the specification calls for.
  5. 05
    Repeat for every panel that differs, then save.
  6. 06
    Re-run Analyze Design so the glass area and the price follow.

What the choice changes downstream

  • Weight — heavier units need heavier hardware, and the hardware rules pick it automatically from the sash size and weight.
  • Glass areaTotal Glass (m²) drives both the glass order and much of the price.
  • Lead time — laminated and coated units are rarely stock items; the difference shows up as a late job, not a warning.

Example

A villa's ground-floor sliders are specified 6 mm clear on the drawing. Changed to 6-12-6 double glazed with a low-e coating, the same design gains weight per sash — and the hardware set the analysis picks changes with it, because the rules key on sash weight.

Common mistakes

  • Specifying glass on one panel and assuming the rest inherited it. Panels are specified individually on purpose.
  • Changing the glass and not re-analysing, so the quoted price is for the old build-up.
  • Agreeing a delivery date on a special coated unit without checking whether it is a stocked product.
