What is a Wedge Gasket?

A wedge gasket (also known as a glazing wedge or wedge seal) is a specific type of compression seal designed to:

• Hold glass securely in the frame or sash
• Provide weatherproofing by sealing gaps between the glass and frame
• Help absorb movement caused by thermal expansion or structural shifts
• Reduce rattling and vibration in the window unit

Installation Position:

The wedge gasket is installed between the glass unit and the frame:

1. After the glass unit has been positioned in the window frame (or door frame)
2. A "setting block" or bead is often used to position and support the glass at the bottom
3. Once the glass is aligned, the wedge gasket is pushed into the gap between the edge of the frame and the glass, typically from the inside. The gasket's shape allows it to locate into the profile groove for a secure fit.
4. It compresses against the glass, holding it firmly in place and forming a tight weatherproof seal

Frequently Asked Questions:

How do I know which gasket profile I need?
If you're unsure which profile matches your windows or doors, we recommend ordering one of our Gasket Sample Packs available in our shop. This will allow you to compare profiles and select the exact match for your needs.

How difficult is it to fit these gaskets?
Fitting is straightforward for anyone with basic DIY skills. The gaskets are designed to locate into the profile groove as you push them into the gap between the glass and frame, creating a secure fit without requiring adhesives or special tools. We recommend measuring the perimeter carefully and adding approximately 6cm extra before cutting to ensure you don't cut the gasket too short.

What's the difference between EPDM, PVC and TPR materials?
EPDM is our most popular material, offering exceptional durability, UV stability and performance in dynamic applications, with a lifespan of 15+ years. PVC is ideal for static applications and comes colour-coded for easy identification. TPR offers excellent deflection recovery and is resistant to oils and abrasion, making it suitable for both static and dynamic applications.

Will replacing the gaskets stop my windows from leaking?
In many cases, yes. Deteriorated gaskets are a common cause of draughts and water ingress. Replacing them with new, flexible gaskets often resolves these issues without requiring expensive window replacements. However, if your window frames are damaged or warped, additional repairs may be needed.
