Cleanroom windows on this site are double glazed units built for cleanroom walls. The frame is a purification-grade aluminium alloy frame, and the glazing is held with PVC beading under which desiccant absorbs moisture so the unit resists fogging. That combination matters in a cleanroom because a fogged vision panel fails at its one job: letting people see through a wall without opening it. The glass is toughened white glass, stated as three to five times the strength of ordinary glass and breaking into blunt small particles rather than sharp shards.
A window should be specified together with the wall and door around it. The frame material here is aluminium alloy, and buyers who need a different frame material should confirm availability in the inquiry rather than assume it, because the product description states the purification-grade aluminium alloy frame for this window family. Opening sizes, quantities per size, and the wall thickness the window must suit should all be listed in the inquiry so the window schedule can be checked against the door schedule on the same project.
Double glazing also gives the buyer a practical checklist: confirm the frame, confirm the beading and desiccant arrangement, confirm the glass type, and confirm the opening size. Flush installation and stainless steel frame variants are treated separately in the guides section of this site, where the product description does not state them as standard window specifications. Those guides explain what is confirmed and what must be asked, so the window family page itself stays within the stated construction facts.
- Frame: purification-grade aluminium alloy.
- Beading: PVC beading with desiccant beneath it to absorb moisture and resist fogging.
- Glass: toughened white glass, 3 to 5 times the strength of ordinary glass, breaking into blunt small particles.
- Use with: cleanroom doors on the same wall, and ceiling panels above, so vision, access and ceiling lines are coordinated.

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.
