Name the supplied object
An insulated glass unit, often called an IGU, glass pack or sealed glass unit, is a glazing assembly. A commercial refrigerator door assembly adds an agreed frame and interfaces. A complete door kit may also include mounting hardware or a receiving frame, depending on the quotation. Specify the contents of the kit instead of relying on the word complete.
Commercial glass manufacturers distinguish insulating glass products, custom glass doors and illuminated glass treatments. CIG’s product categories show this distinction. For a MARKOOL project, the proposed drawing and written supply list define the actual scope. A catalogue family or product name does not establish the parts included in a particular order.
Scroll across the table to see all columns.
| Requested scope | Typical integration question | Record before comparing |
|---|---|---|
| IGU / glass pack only | Will this glazing be integrated into the buyer’s existing or new frame? | Glass-unit dimensions, thickness, edge construction and any connections |
| Framed door assembly | Which existing cabinet interfaces will the assembled door use? | Door envelope, gasket, hinges, handle and supplied fittings |
| Door and frame kit | Which receiving frame and installation parts belong to the package? | Opening drawing, frame sections, fasteners and installation responsibility |
| Complete refrigerated cabinet | Which cabinet and refrigeration configuration is being selected? | Model, holding requirements, loading, branding and destination |

Build a line-by-line supply list
Give each quote the same worksheet revision. Mark every item included, excluded, supplied by the buyer or unresolved. Record a part or drawing reference when available. A blank line remains an open question; it does not establish a zero price or an included part.
List parts reused from an existing cabinet explicitly. Reuse can affect fit, service access and the checks required for the replacement sample. Keep the responsible party beside each interface so a supplier’s glazing scope does not silently become responsibility for the entire refrigeration system.

| Line item | What to identify |
|---|---|
| Glazing | Unit size, panes/build, coating or treatment, spacer and edge seal |
| Frame and seal | Door frame, receiving frame if any, gasket and retention/contact detail |
| Opening hardware | Hinges or tracks, rollers, closer, stops, handle and lock |
| Heating | Glass heater, frame heater, control and named electrical interfaces |
| Illumination | Artwork layer, logo lighting, driver, wiring and service access |
| Installation parts | Mounting brackets, fasteners, leads and buyer-provided items |
| Packing and spares | Packing configuration, protection and separately quoted spare parts |
Compare the same configuration and quantity
Use one door or glass-unit drawing revision for each comparison. Identify quantities per size, handedness and configuration. A pilot with several different doors can have a different cost basis from a batch of identical units. Record sample quantity and expected batch quantity separately.
Keep the destination and proposed packing or delivery scope consistent. Ask the quotation to identify currency, validity and the agreed delivery basis. A glazing-only price, a complete door price and a price including freight cover different items; the scope worksheet makes those differences visible before negotiation.
Separate unit prices from one-time and sample charges
Request separate lines for the quoted unit, sample, artwork or engineering work, tooling if proposed, packing, transport and agreed spares. Record how any sample charge or one-time fee relates to the later batch. Do not assume a credit, refund or waived fee unless it is part of the quotation.
The free cooler mockup and loading-plan service concerns the agreed digital deliverable. Its first-draft timetable starts after the necessary project information is complete. A physical glass or door sample has a separate technical, price and scheduling decision. Keep both deliverables named in the brief so the digital service promise is clear.
Keep heating, Low-E and logo lighting identifiable
Low-E identifies a coating choice. A glass heater, frame heater and illuminated logo describe different functions. In the proposed configuration, identify which functions are included and which power or control components belong to each one. Record connection and servicing interfaces alongside the visual treatment.
For a heated freezer door, agree the cabinet and room conditions that the sample must be assessed against. For a logo door, agree the artwork proof, transparent product-view area and lit/unlit appearance check. A picture does not establish the electrical package, condensation performance or compatibility of an existing cooler.
Close the scope with a controlled approval set
Before releasing a batch, keep the accepted drawing revision, supply worksheet, artwork where applicable, sample decision and quotation reference together. List any unresolved item with a responsible party and the next evidence required. Record an approved substitution separately so the next order can identify which configuration was actually supplied.
Use a short first enquiry: required object, application, destination and quantity, plus the dimensions or files already available. The detailed worksheet can follow as the proposal develops. This keeps the buying path simple while making the eventual quotation comparable and traceable.
Apply the checklist
Define the scope for a comparable quotation.
Send the requested glass or door scope, application, quantity and destination. Add the scope worksheet as the proposal develops, with buyer-supplied and unresolved items identified.
