Double-leaf cleanroom doors serve the wider openings on a cleanroom plan: equipment routes, material transfer routes, and rooms where a single leaf would be too narrow for the traffic. This page states the brochure dimensions for double-leaf openings as 1500 mm and 1800 mm wide, with a height of 2100 mm. Those figures are brochure dimensions, quoted from the product brochure, and they describe the opening sizes listed there; any opening outside those sizes, and any split between the two leaves, should be confirmed in the inquiry.
Each leaf of a double door carries the shared cleanroom leaf structure: aluminium door frame and aluminium leaf frame, colour-coated or melamine board panel, aluminium honeycomb core, rounded lock operable with the elbow, double-spring rising sweep strip that settles smoothly and seals well, quiet wear-resistant hinges, internal stiffeners, and an anti-fog double glazed toughened glass vision panel. The two leaves together must also be considered as a pair: confirm how the meeting stiles close, how the inactive leaf is held, and how the sweep strips meet the floor finish, because those pair details are project details to settle in the inquiry.
Double doors are also the natural partner of the vision panel and opening size guide on this site, which sets the double-leaf sizes alongside single-leaf and unequal-leaf sizes in one comparison table. When a project mixes leaf arrangements, schedule each opening separately by arrangement and size rather than grouping them, so the factory schedule, the lock schedule and the vision panel schedule all stay consistent across the set.

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.
