Customizing Rubber Window Glazing Seals

Windows can’t do much good if they can’t keep air, water and other fluids from leaking out. No one wants to have to pile up with blankets when cold air gets into the house or make constant boat repairs in response to water damage. However, quality rubber window glazing seals allow for tight fits minimize chemical and mechanical wear and maintain comfortable temperatures. You and your team may have customized other rubber parts in the past, but a run of rubber window glazing seals may mark a new undertaking.

Planning your investment in custom window glazing solutions may seem complicated, but the process does not need to overwhelm you and your colleagues if you put all you can into the preparation.

Rubber glazing gasket pieces are essential for preventing costly and often dangerous leaks on boats, in homes, in cars and in fire protection and drainage systems. While useful across residences and commercial buildings of all kinds, they are particularly important across the aerospace, agricultural, marine and electronics sectors.

Customizing Rubber Window Glazing Seals

What factors should you and your team consider as you plan your customization? Before even thinking about partner companies, you should set aside the time to know your project goals and the environment of your application as well as possible.

As you establish your goals for your window rubber seal customization, you and your team should think about the operating temperature range of the application, the necessary complexity of a design, ease of installation, any chemicals present in the system, any environmental sustainability goals your team may have and, of course, your company’s budget.

Knowing the application’s environment from all angles, in particular, will help you and your team select a rubber material for your parts as easy as possible. Different materials come at different costs and withstand forces differently. For example, Viton rubber is especially notable for its resistance to mold buildup, damage from high temperatures and chemical wear. On the other hand, EMDM rubber can withstand significant levels of wear from UV radiation, ozone and water.
