What are the key differences between framed and frameless cleanroom windows?

Framed cleanroom windows feature a 2.75”-wide outer frame made of 304-grade stainless steel or polypropylene that mounts tightly against the wall, allowing the glass pane to be recessed for a smooth, durable, and easy-to-clean surface. In contrast, frameless clean room windows use a BioSafe flush-mount system with no hardware or fasteners, including 0.25” thick tempered glass panels that overlay the wall on one or both sides, attached to an internal stainless steel frame. They are designed without cracks or crevices for easy disinfection and include a black faux border behind the glass to prevent scratching.
