To request a useful aluminum window or door quotation, start with an opening schedule, quantities, project location and intended system type. Add drawings, glazing requirements and the required delivery date when available. If a detail is undecided, mark it as “to be confirmed” so assumptions can be separated from confirmed specifications.
Start with an opening schedule
Give each opening a unique reference, such as W01 for a window or D01 for a door. List the width, height, quantity and opening style for each reference. State the measurement unit and explain whether the dimensions refer to the structural opening or the finished frame. Include drawing revision numbers so suppliers quote the same information.
| Item | What to provide |
|---|---|
| Project location | Country, city and site context |
| Opening reference | A unique ID matching your drawings |
| Dimensions | Width × height, unit and measurement basis |
| Quantity | Number of units for each opening reference |
| System type | Casement, sliding, fixed, door or another required configuration |
| Glazing | Specified glass build-up, or items requiring review |
| Finish | Required color and finish, if selected |
| Schedule | Target site date and relevant procurement milestones |
Make performance requirements explicit
Provide the project specification or the requirements set by your designer or consultant. Identify any required thermal, acoustic, wind, water or safety performance, together with the applicable testing or approval requirements. Ask the supplier to identify evidence that applies to the proposed system and configuration. A general brochure should not be treated as proof that a particular opening meets your project specification.
For a thermal break window inquiry, include the intended opening style and glazing requirements alongside the performance specification. If you are still selecting a system, review the product range and list the decisions that need clarification.
Separate supply from site responsibilities
Ask the quotation to state what is included and excluded. Clarify who provides site measurements, installation, fixing details, sealants, unloading and any local approvals. Confirm packaging requirements and the destination for delivery or collection. Request that freight, taxes and other commercial assumptions be identified separately where applicable.
Do not compare quotations by total price alone. First check whether the quoted dimensions, glazing, hardware, finish, quantities and supply scope match. Ask for substitutions to be clearly identified before comparing prices.
Questions buyers often ask
Can I start without final drawings?
You can prepare an initial inquiry using preliminary dimensions and quantities. Label them as preliminary and ask what remains necessary before a firm quotation or production approval. Preliminary information should not be treated as an approved manufacturing schedule.
What if the glazing has not been selected?
Provide the project requirements and identify glazing as an open decision. Request a proposed build-up and the evidence needed for review by your project team. Avoid assuming that one glazing option fits every opening or destination.
Should installation be included in the quotation?
State whether you need supply only or installation support. Ask the supplier to confirm the available scope in writing. Keep responsibility for site work and interfaces explicit before ordering.
How can I compare two quotations fairly?
Use the same opening schedule and specification for both. Review exclusions, alternatives, payment assumptions and delivery scope as well as the product configuration. Resolve unclear items before treating either total as comparable.
