What is clean room window ?

Updated: May 6, 2023

Clean room window, double-layer hollow 5mm tempered glass, can be matched with machine-made sandwich panel and handmade sandwich panel to create the integration of clean room wall and window, with beautiful overall effect, good sealing performance and good sound insulation and heat insulation effect. The clean room window can be matched with 50mm manual clean room wall or machine-made clean room panel to break the shortcomings of traditional glass window, such as low precision, non-sealing and easy fogging. It is a good choice for the industrial application observation window of the new generation of clean space.


The double-layer clean room windows are double-layer hollow glass, with good sealing performance and thermal insulation performance. According to the shape, it can be divided into rounded edge and square edge purification window; According to the material, it can be divided into: one-time forming frame purification window; Aluminum alloy frame purification window; Stainless steel frame purification window. It is widely used in purification engineering, covering medicine, food, cosmetics and electronic manufacturing industries.

Features of double-layer clean room window:

(1) Sound insulation: meet people's needs for lighting, viewing, decoration and environmental protection. Generally, insulating glass can reduce the noise by about 30 dB, while insulating glass filled with inert gas can reduce the noise by about 5 dB on the original basis, which can reduce the noise of 80 dB to 45 dB, which is very quiet.

(2) It has good thermal insulation performance: the K value of heat conduction system, the K value of single 5 mm glass is 5.75 kcal/MH ℃, the K value of general insulating glass is 1.4-2.9 kcal / MH ℃, and the K value of insulating glass filled with argon and sulfur fluoride gas can be reduced to 1.19 kcal/MH ℃. Argon is mainly used to reduce the K value of heat conduction, while sulfur fluoride gas is mainly used to reduce the DB value of noise, these two gases can be used alone or mixed in a certain proportion.


(3) Anti condensation: in the environment with large indoor and outdoor temperature difference in winter, condensation will occur in single-layer glass doors and windows, while there will be no condensation if desiccant is added to double-layer insulating glass.
