Gasket is a component that is applied between two surface areas, usually to provide a barrier of some kind. The most common use is for sealing. However, gaskets also provide cushioning, prevent vibration and sound reduction.
Window gaskets provide sealing and insulation and can help hold window glass in place. They are made of rubber materials and installed along the edges of stationary windows such as the windshields for agricultural, forestry, and mining equipment. Window gaskets are also used with the viewing windows on machine or equipment enclosures. Because they are industrial rubber products, window gaskets like these do not include the flocked seals that are used in cars with moveable glass.
The purpose of double glazing gasket is to keep the window sash in place, when fitted into its upvc frame. This provides a weatherproof seal. Window gasket is usually made from black rubber, and sometimes in white rubber as well. Either way, it does the same job, which is to provide insulation for the window.
Types of window gaskets
Depending on the window gasket application, engineers can choose foam profiles, D-shapes, C-channels, U-channels, or various types of glazing seals. In the mobile equipment and enclosure industries, window channels that feature a locking or self-locking mechanism are often used. Locking channels are two-piece gaskets that lock into position with a lock strip or key. Self-locking channels are one-piece window seals that do not require these attachment mechanisms.
Window gasket materials
To avoid gasket failure, always consider the environment when selecting rubber materials. With mobile equipment, EPDM window gaskets are typically used because they can withstand outdoor conditions. For the viewing windows on equipment enclosures, there are different considerations.
Although window gaskets can be made from a variety of different materials, EPDM rubber gaskets are one of the most common types. Whether your project calls for a single prototype or large production runs, we provide you with EPDM window gaskets that meet or exceed your expectations.
EPDM rubber gaskets and window seals are for stationary windows that aren’t exposed to oils, gasoline, kerosene, or concentrated acids. These locking gasket window seals provide excellent resistance to the following:
• Severe weather conditions
With outstanding color stability, odor-free characteristics, and high heat resistance, windshield gasket seals can be used in a wide range of industries and applications.
Window glass thickness
Measure the thickness of the window glass so that you can determine the size of the edge that your window gasket needs to grasp and hold. There needs to be enough room for the glass to fit inside the gasket, but not so much room that the glass will rattle or fall out.
Locking gasket installation
During gasket installation, workers will find that there’s some extra rubber for each window. That’s by design since all rubber gaskets experience some shrinkage over time. When you install a locking gasket, push the ends together and leave the extra material in the loop that forms. Then press down the loop so that you force more material into the gap. This keeps the gasket from becoming over-stretched.
Next, spray the locking gasket with a silicone-based lubricant or soap and water. Then use a hand tool to unlock the gasket so that it’s ready for window glass installation. Install the glass on the body size first, resting the bottom of the glass in the locking gasket. Then use a plastic installation tool as you work the gasket’s lip over and around the glass. Finally, use a hand tool to the lock the gasket back into itself.
