Flush windows are windows whose face sits level with the wall face, leaving no ledge where dust can settle and no recess that complicates cleaning. That is an attractive idea in a cleanroom, and it is exactly why this guide treats flush installation with care: the idea is easy to state, but the installation method that achieves it is a project detail that must be confirmed, not a standard detail that can be assumed from the window family page.
The stated window construction on this site is a purification-grade aluminium alloy frame with PVC beading, desiccant beneath the beading to resist fogging, and toughened white glass. That construction is fully stated and can be ordered. What is not stated is the flush installation method: how the frame seats into the wall, how the wall finish meets the frame, and how the seal line is made flush on both faces. Those are installation facts, and the product description used for this site does not give them, so this guide does not invent them.
A buyer who needs flush windows should therefore send the flush requirement as an explicit inquiry item, together with the wall construction, the wall finish on both sides, the window opening sizes, and the cleaning requirement that motivates the flush detail. The supplier can then confirm whether a flush arrangement can be supplied for that wall, what the frame seating will be, and whether any part of the standard window construction changes to achieve it. Until that confirmation arrives, the safe specification is the standard window construction on the window family page, with the flush requirement recorded as an open item rather than written into the order as a standard feature.
No installation dimension is stated in this guide, because no installation dimension is given for the flush method in the product description. Dimensions that matter for installation, such as frame seating depth and wall finish thickness, should be taken from the confirmed installation detail for the project, not from a generic guide. That discipline keeps the guide honest: it explains the question to ask and the information to send, without pretending to answer a construction question it has no evidence for.
- Flush idea: window face level with the wall face, no dust ledge, easier cleaning.
- Not standard: the flush installation method is not stated and is subject to confirmation.
- Stated window: purification-grade aluminium alloy frame, PVC beading with desiccant, toughened glass.
- Send with the inquiry: wall construction, wall finishes, opening sizes, cleaning requirement.
- No dimensions: no installation dimension is stated in this guide.

How to read the specifications on this page
Dimensions and construction details on this page follow the Lairun product description for the component family shown. Door opening sizes quoted on this site are brochure dimensions: they describe the opening sizes listed in the product brochure, and any non-standard size should be confirmed in the inquiry. Aluminium profile codes are listed by code only; no profile dimension is stated where the product description does not give one. Items that the product description does not specify are marked for inquiry confirmation rather than described as available options, so buyers are not led to assume a mechanism, a load figure, or a material variant that has not been evidenced.
What to put in your inquiry
Send the opening sizes you need, the leaf arrangement, the surface finish you prefer, and the ceiling layout where the components will be installed. State the quantities per size, the site conditions, and the delivery location so the component list can be checked line by line. Where this page lists an item as subject to confirmation, include that item explicitly in your message so it is answered before any order is placed. Please confirm the minimum order quantity and the lead time in your inquiry, because this site does not publish those figures. Certificates are available upon request; please ask for the documents you need and state which project they are for.
