How Do Window Installers With Their Own Fabrication Shop Stop Cutting List and Glass Order Errors?

Window installers with their own fabrication shop still write cutting lists and glass orders by hand. We build a link from order to shop floor.

Quick answer — TL;DR

Installers who fabricate their own uPVC or aluminium frames often have a gap between the order and the shop floor: cutting lists, reinforcement, hardware picks and glass sizes worked out by hand or retyped into the saw software. We build a link that takes each confirmed order's frames, produces the cutting list, hardware pick list and sealed unit order from your system's rules, and tracks each frame through the shop to dispatch.

A frame 10mm short on the bench

The order came in from the surveyor. The fabrication manager typed the frames into the cutting software, worked out the glass sizes on a calculator and emailed the sealed unit order. One frame's width was typed wrong. The profile was cut short. The glass for another frame was calculated with the wrong bead deduction and arrived too big. Two remakes, and the fitting date moves.

Where the shop loses accuracy

Small and medium fabrication shops often run with good machines and experienced people, but the information reaching the machines is retyped. Every retype is a chance for error, and glass is usually ordered separately from the frame build.

  • Frame details are retyped from the order into saw or machining software.
  • Glass sizes are calculated by hand from frame sizes and deductions.
  • Hardware, reinforcement and gaskets are picked from memory.
  • Frames in the shop are tracked on a whiteboard.
  • The office cannot see where a job is without walking onto the shop floor.

What shop errors cost

A miscut profile and a wrong-size sealed unit are both wasted material, and they push the fitting date. Missing hardware found at assembly stops the frame. Office staff answering customers do not know when frames will be ready. And the fabrication manager spends time on data entry rather than running the shop.

  1. Confirmed orders flow from your quoting system with each frame's style, sizes, profile, colour, glass and hardware.
  2. Cutting lists are produced from your profile system's deduction rules and sent to your saw or machining software where it accepts imports.
  3. Sealed unit sizes are calculated from the same rules and the glass order is sent to your glass supplier in their format.
  4. Hardware, reinforcement and gasket pick lists are produced per frame.
  5. Each frame gets a label with a barcode or QR code, scanned at cutting, welding, cleaning, hardware, glazing and dispatch.
  6. The office sees each job's frames by stage, and the fitting date is warned if a job is behind.

Profile rules and deductions come from your system supplier and your fabrication manager. We encode them, we do not invent them.

What the shop looks like after

The fabrication manager checks rather than types. Cutting lists and glass orders are consistent with each other because they come from the same data. Hardware is picked from a list. Everyone can see where each frame is. And remakes caused by transcription become rare.

Where your quoting and machining software already talk to each other, we connect the parts that do not rather than rebuild what works.

Shop floor tracking also improves what the office can tell customers. When a homeowner rings to ask about their frames, the office can see whether they are cut, welded, glazed or on the rack for dispatch, instead of walking onto the shop floor to ask. The fitting diary can be planned around frames that are genuinely ready, not frames that should be ready.

Is your shop floor retyping?

  • Frame details are typed into the saw software by hand.
  • Glass sizes are worked out on a calculator.
  • Remakes happen because of a typed figure.
  • Frame progress lives on a whiteboard.

Still have a question?

Ask us directly — a senior engineer will get back to you.

Ask about your project

Does it work with our saw and machining software?

Where it accepts file imports, yes. We check what your machines and software accept before promising anything.

Can it order glass from our supplier?

Yes, in the format your glass supplier accepts, by email or their ordering system.

Do we need new machinery?

No. This is about the information reaching the machines, not the machines themselves.

What affects the cost?

Your quoting and machining software, the number of profile systems and the level of shop floor tracking you want.
