Gaskets & Seals

Rubber gaskets and seals are vital for the construction of double glazing and window frames. They provide a weatherproof and soundproof seal between the glass and the frame, preventing drafts, water, and noise from entering the home.
At DG Supplyline, we offer a wide range of gaskets and seals for all types of windows and doors to keep your home comfortable and secure, including bubble gaskets, E-type gaskets, wedge gaskets, flipper gaskets, U-channel gaskets, and tear-off gaskets. Not quite sure which one is best suited to you? Our staff can help you choose the correct gasket for your specific needs.

The Benefits of Rubber Gaskets

Rubber gaskets are easy to install, they don’t require any adhesives or tools to be fitted and are designed to be pushed into place. Using soapy water or glass cleaner can significantly help the installation process. Once in place, the gasket creates a tight seal that is durable and long-lasting.

It’s important to note that there is no set lifespan for rubber gaskets, as it depends on usage over time. However, we recommend inspecting your gaskets for damage every few years to make sure they’re still effective and can protect your home.

Rubber gaskets also provide soundproofing benefits, which is especially important for homes located near busy roads or railway tracks. The gaskets prevent noise from entering the home so that you can enjoy a more peaceful living environment.

Rubber Gaskets for Window Repairs

If you’re experiencing drafts or water leaks coming from your windows, it may be time to replace your rubber gaskets. We can cut gaskets to any metre length required and have a variety of sizes and shapes in stock. Our staff will be happy to help you find the correct seal for your window repairs, so feel free to get in touch.

Rubber Door Seals

Rubber door seals are also an important component in the construction of doors, providing a weatherproof and soundproof seal between the door and the frame. We offer a range of rubber door seals for all types of doors, including hinged, sliding, and bi-folding doors.

Choosing the Correct Seal

It’s important to choose the correct seal when repairing or replacing gaskets. If you’re unsure which seal to choose, you can send in a sample of your existing gasket and our staff can usually identify it. Choosing the correct seal will ensure that your windows and doors are protected from drafts, water, and noise for years to come.

Identifying Rubber Door Seals & Window Glazing Gaskets

There are so many different profiles of rubber gaskets around that stocking them all is difficult. If you need a special type of gasket or seal that you can’t see shown in our standard range, let us know. We regularly review which gaskets are the most popular and try to keep stock accordingly.

Please ensure you have read our terms and conditions about ordering gaskets. Window gaskets are cut to length with your order and can’t be returned for refunds.
