Cleanroom Doors and Windows: An Opening Schedule for Procurement

Prepare a cleanroom door and window RFQ with clear openings, wall thickness, hardware, glazing and installation responsibilities for an overseas project.

Technical purchasing guide · 13 November 2026 · K-STONE / AILV

Start With the Opening Schedule

A cleanroom door and window RFQ becomes easier to compare when every opening has a reference on the room layout. Record the clear passage, adjoining wall construction and operating arrangement for each door set. Include observation windows in the same schedule so their dimensions and frame interfaces can be reviewed with the cleanroom wall panels.

For an overseas project, attach the current drawing revision, delivery destination and installation sequence. Mark unresolved items for review before manufacture. This guide is a practical procurement checklist, using the planning approach described in the official abstract of ISO 14644-4:2022 as background.

What to Put in a Cleanroom Door and Window RFQ

Schedule Item	Information to Provide	What the Quote Should Identify
Opening Reference	Door or window number, room reference, quantity and drawing revision.	A matching item reference for each offered assembly.
Dimensions	Required clear passage, structural opening, wall thickness and finished floor level.	Frame dimensions, installation allowance and which dimensions require site verification.
Door Operation	Single or double leaf, swing direction, manual or powered operation and movement of equipment or trolleys.	Leaf arrangement, hardware, controls and required power or signal connections.
Observation Glazing	Window position, size, visibility needs and any specified glazing construction.	Glass build-up, frame details and the connection to the wall.
Cleaning and Room Use	Cleaning agents, exposure, washdown needs and specified pressure relationships.	Proposed facing, frame and sealing materials, with required compatibility or performance documents.
Supply and Site Work	Required profiles, fixings, seals, packing, unloading and installer responsibilities.	Included components, exclusions, site adjustments and agreed inspection records.

Keep Clear Passage and Structural Openings Separate

The clear passage is the usable opening when the door is in its intended open position. The structural opening must also accommodate the frame and installation detail. Mixing these dimensions can leave equipment access unresolved after the panels have been ordered. Ask the cleanroom door supplier to show both dimensions on the submitted drawing, including the view used to define handing.

For replacement doors or cleanroom observation windows, provide measured openings, wall sections and photographs of the retained frame and joints. A matching nominal panel thickness alone does not establish that a replacement assembly will fit.

Coordinate Hardware, Services and Acceptance

List hinges, closers, locks, seals and any powered controls against each door reference. Where interlocks, access control or fire requirements apply, identify the responsible specialist and request the documents required for the offered configuration. The project designer should confirm escape and fire requirements under the applicable local rules.

Agree who checks frame alignment, glazing, seals, operation and service connections. Where the project requires pressure or leakage testing, specify the method, installation condition, acceptance criteria and responsible party. A product description cannot establish the performance of the installed room.

AILV Materials and K-STONE Installation Coordination

For material procurement, review AILV cleanroom doors, windows and vision panels alongside the cleanroom wall and ceiling panel range. AILV can discuss a coordinated enclosure supply package against the selected drawings and item schedule.

If the enquiry includes site assembly or engineering interfaces, review K-STONE cleanroom installation services. State whether you need installation guidance, site coordination or installation work, and agree the available scope, local labour and handover responsibilities for the destination.

Procurement Questions

What information is needed for a cleanroom door quotation?

Send the opening schedule with room references, quantities, clear passage sizes, wall thickness, opening direction, hardware and required project documents. Identify the drawing revision and delivery destination so each quoted door set can be matched to the layout.

Can cleanroom panels, doors and observation windows be quoted together?

Yes. Request a coordinated enclosure package and identify the panel, frame and glazing interfaces on the same drawing revision. List profiles, seals, fixings and installation work separately so the included scope can be checked.

Does a cleanroom door need a universal airtightness rating?

Use the project pressure design, operating conditions and applicable test specification to define the required door assembly and acceptance checks. Ask for evidence for the quoted configuration rather than assuming that the word airtight establishes a tested leakage value.

Prepare Your Opening Schedule

Send the room layout, door and window references, quantities, selected wall thickness, delivery destination and required documents. Attach existing-site photographs for replacements and mark undecided hardware or control items. Request a cleanroom enclosure quotation with the materials and site support you want included.

Technical Source and Scope

ISO 14644-4:2022 — Cleanrooms and associated controlled environments — Part 4: Design, construction and start-up, published November 2022. The official abstract describes a requirements-led process covering design, construction and start-up, including refurbished and modified installations. It leaves the technological and contractual approach to the project.

This article uses the publicly accessible official abstract as background. The schedule and purchasing recommendations are K-STONE / AILV guidance, not quoted ISO clauses. The standard is an existing reference, not a new announcement. Product evidence, local fire and safety rules, and project acceptance criteria require separate review.
