Product Introduction

The cleanroom window gasket is an extruded silicone glazing profile installed between the glass edge and the aluminum retaining channel. Its wedge or keyed section applies continuous pressure without allowing hard metal contact with the pane. In double-glazed observation windows, the gasket works with the spacer and frame system to position both panes, accommodate small dimensional variation and present a smooth perimeter suitable for controlled interiors.

Key Features

A shaped glazing wedge distributes retention pressure along the glass edge.

Resilient silicone cushions the pane and accommodates small frame and glass tolerances.

The continuous profile closes the visible perimeter without exposed mechanical fasteners.

Custom corner joining supports rectangular windows with consistent compression on every side.

Customer Product Concerns

Cleanroom glazing needs continuous edge support without point loading the glass or leaving irregular recesses around the visible perimeter.

Direct metal contact creates concentrated stress at the glass edge.The resilient gasket separates the pane from the retaining channel and distributes compression.

Variable glass and frame tolerances create loose sections or excessive insertion force.The wedge geometry is matched to the actual channel and glazing thickness for controlled interference.

Open or uneven corners interrupt the cleanable perimeter seal.Cut and joined corner sections maintain a continuous visible gasket line around the window.

Migrating oils or dark marking can contaminate adjacent light-colored finishes.A suitable non-marking silicone compound is selected for contact with the specified glass and frame finish.

Typical Applications

Flush cleanroom observation windowsDouble-glazed cleanroom partitionsPass-through viewing panelsLaboratory wall windowsProcess enclosure glazing
