Custom Window Seals

Static & Dynamic Window Seals Made to YOUR Specifications

All window seals have the same basic job, whether they’re used on semi-trucks or recreational watercraft. The challenge, however, is finding something flexible enough to match your design needs while providing the durability and weatherability needed to withstand long-term exposure to the elements.

The effectiveness of a window seal comes down to its material and design. You know what you need your rubber gasket window seal to do but might need help choosing a material or reworking a design that previously didn’t work. That’s where we come in. From semi-truck window seals to rubber gaskets for marine portholes, we have the equipment and expertise to turn your designs into a high-quality product.

Static and Dynamic Window Seals Made to YOUR Specifications

When you work with Northwest Rubber Extruders, the custom window seal production process is fairly straightforward. Simply provide us with your seal profile and material specification, and we’ll take it from there. We produce seals for both static and dynamic windows, and nearly any profile, length, or thickness is possible.

We manufacture our own dies and molds to ensure accuracy and use only the best materials to ensure quality and durability. Come to us with your design, and we’ll create a custom window seal that solves even the most complex sealing challenges.

Window Seals for Trucking and Marine Industries

A static window is one that doesn't move or open in any way. A dynamic window is one that can be rolled up and down or that opens on a hinge. Northwest Rubber Extruders can produce static window seals and dynamic window seals that match your exact specifications.

No matter how large or thick the window glass is, or where the window will be installed, we can provide a durable custom seal that fits perfectly. We provide:

  • Passenger Vehicle & Semi-Truck Window Seals: for cars, semi-trucks, RVs, buses—we can produce seals for any vehicle with a window
  • Architectural Window Seals: anything from storage sheds to skyscrapers—if it’s got windows, we can deliver the seals
  • Marine Window Seals: from small fishing boats to high-end yachts, we can manufacture custom, watertight rubber gaskets and port-hole window seals for all types of watercraft.

Durable Materials Ensure Quality in Every Design

We manufacture custom window seals from durable and flexible materials like EPDM, Neoprene, and Santoprene to achieve the best results. EDPM is often preferred for semi-truck window seals of its resistance to weather and extreme temperatures, both of which are critical factors for vehicles that spend countless hours on the road. Neoprene works best for marine applications because it provides high weather and temperature resistance, along with withstanding grease and oil. Santoprene works well for architectural or automotive window seals because of its temperature resistance and long-term aging properties.

Whatever your needs, we have the right materials for your rubber gasket window seal design.
