Looking for glazing rubber suppliers for your next project? Qualiform is a leading provider of rubber extrusion services, offering a full range of rubber window glazing seals for a wide variety of industries. As a certified manufacturer of custom rubber products, we utilize advanced rubber molding technologies to ensure high-level precision for every project. So, we can reliably produce the ideal rubber window seal extrusions for your application.
What are Rubber Window Glazing Seals?
Rubber window glazing seals are designed to keep air, water, and other fluids from leaking in or out of the window. These are most commonly found in residential and commercial properties as a means of minimizing energy consumption. Rubber window glazing seals are also referred to as weather stripping, window glazing gaskets, window glazing strips, and glazing rubber seal strips. There are also rubber glazing beads, which are much smaller parts while offering similar sealing properties.
Here at Qualiform, we offer more than 40 years of experience in rubber extrusion. So, we can develop custom extrusion profiles to suit your specific window configuration. As a result, the glass will be more secure, and the seal can provide reliable insulation and waterproofing as well as protection from intense vibrations.
Most importantly, we design our glazing rubber products to offer high-level performance and resistance in even the harshest environmental conditions. In fact, we carry a full selection of both commercial and specification grade elastomers. So, we can ensure your glazing gaskets, seals, and other parts are tailored to your specific application.
Rubber Window Glazing Seal Applications
The most common application for window rubber seals is weather stripping and insulation for both residential and commercial windows. However, these seals can also be used to secure windows to doors, cars, trucks, and more! In fact, marine window glazing rubber is a crucial component for boats, as it can prevent severe leaks and flooding. Some other applications of glazing channel rubber seals include:
- Garage Doors
- Sunroofs
- Boat Hatches
- Windshields
- Drainage Systems
- Fire Protection
Additionally, window glazing strips and seals are useful in many different industries. Industries such as construction, transportation, marine, electronics, agriculture, and even aerospace depend on these products for their sealing capabilities as well as their superior weather and ozone resistance.
How to Choose the Best Glazing Seal for the Job
Getting the best performance window glazing seals means choosing the ideal rubber compound for your application. The difference between a neoprene glazing channel and an EPDM glazing gasket could significantly impact performance. So, choosing the right compound requires careful consideration of various factors:
- Industry
- Design specifications
- Environmental conditions
- Operating temperature range
- UV and chemical resistance
- Installation methods
For example, EPDM is a uniquely versatile compound used in a variety of applications. Not only does this compound offer reliable performance for window seals, but it is also found in vehicles, safety equipment, medical equipment and more. However, EPDM has extremely poor resistance to oils, gases, and fuels. Therefore, it should not be used for any applications involving those types of substances.
Here at Qualiform, we offer a comprehensive selection of high-quality rubber compounds to ensure optimal performance in any application.
- Butyl Rubber
- EPDM Rubber
- Natural Rubber
- Neoprene Rubber
- Nitrile Rubber
- Rigid & Flexible
- Synthetic Rubber
- Thermoplastic Elastomers (TPE)
- Viton Rubber
So, how do you know which compound is best for your project? If you are unsure of which compound will provide the performance you need, discuss your options with our technical staff. We are available to answer any questions you have and can provide professional recommendations based on your industry and application.

Materials Used in Rubber Extruded Products
To create a custom rubber extrusion, rubber extrusion companies think about a number of design factors, all related to the application. One of the first things considered is material. Rubber material choice depends entirely on how it will match the application requirements. Then, our rubber extrusion experts plan out the shape of the die. They may also consult their standard rubber die list, but they make new dies for a custom extrusion.
Based on the required properties and application of the finished extrusion, rubber extrusion company, Qualiform can advise on the best material for the extrusion. Additional consideration will be given to any secondary processes that are required. Custom compounds and fiber integration can be used when needed.
Natural Rubber
Natural rubber provides excellent acid, chemical and abrasion resistance.
Silicone Rubber
Silicone rubber is an FDA-certified elastomer that maintains its form and properties when exposed to both high and low temperatures.
Viton
Viton provides superior heat, chemical and weathering resistance.
Nitrile
Nitrile, aka nitrile rubber, NBR (nitrile butadiene rubber), acrylonitrile butadiene rubber, Perbunan or Buna-Nis, is highly resistant to oils and ideal for O-rings, hoses or hydraulic seals.
Neoprene
Neoprene has high tensile strength and resists heat, fire, UV rays, water and oil.
Butyl
Butyl delivers low air flow permeability.
SBR
SBR (styrene-butadiene rubber) is used in applications that require high abrasion resistance.
EPDM
EPDM (ethylene propylene diene terpolymer) is ideal for applications that involve heat, aging, ozone, oxidation and ultraviolet rays. Can be used for sponge rubber, foam rubber, weather-stripping, tarp straps, door gaskets, window gaskets and roofing membrane.
Benefits of Choosing Rubber Extrusion
There are many reasons to choose rubber extrusion. First, it offers great freedom of design. You can request parts in nearly shape and size, and rubber extrusion companies can use nearly any rubber material. This means that you also have many choices when it comes to the qualities your part will exude. Another great benefit of rubber extrusion is that it makes parts that are both strong and flexible and soft.
