Full Lite with 5 Lite: one pane, not five

Written for whoever is turning a glass spec into an order.

A glass spec on a door order often reads like two answers to the same question:

Glass: Full Lite Clear Glass — 5 Lite

Read quickly, that looks like five pieces of glass. It is one.

The two words are about different things

Full Lite describes how the slab arrives: one pane, the whole opening, already glazed at the factory. Nothing about the glass is left for the shop to buy or fit.

5 Lite describes how the finished door looks: that single pane divided into five sections by grids — the bars laid over the glass, also called grilles or muntins.

So the line is neither a contradiction nor a quantity. It is a panel that comes with its glass in, and a grid set that makes one pane read as five.

What that means on the order

The mistake is worth naming, because it goes wrong in both directions at once. Reading the “5” as a count orders five sheets of glass that will sit in the rack for good — and orders nothing at all for the grids, which are the one part actually missing. Either way the order looks complete. Nobody finds out until the door is on the bench.

A unit with sidelites

Grids go per glazed panel, not per opening. A unit written as a row of widths —

1/8 x 2/6 x 2/6 x 1/8 x 6/8 x 1-3/8"

— is two leaves flanked by two sidelites: four panels, all glazed, so four grid sets. Counted as one door, the order covers a quarter of what the job needs.

When “Full Lite” stands alone

No number beside it means the pane stays whole, and there are no grids. The words only become a division when a lite count is written next to them.

And when the slab is not full lite

A door quoted with glass but without “full lite” arrives bare, and its lites are a real material to buy — there the count is a count. The rule turns on the words “full lite”, not on the word “glass”, and it has to: keyed on the wrong one, every glazed door in the shop would quietly stop ordering the glass it genuinely needs.

Where this came from

DoorPrep is shop software for door and millwork prep shops. It reads the sticker or the packing slip, works out the route each door needs, and puts the numbers above on the job itself — so the person at the bench is not doing this on the back of the slip.
