FAQs
Are these packers weather-resistant?
Yes, they are made from high-quality plastic designed for use within window and door frames, making them resistant to standard environmental conditions.
Can these be cut to size?
While the material is durable, they can be trimmed with appropriate cutting tools if necessary for specific frame configurations.
How do I choose the right size?
Measure the clearance between your glass unit and the frame rebate and choose the packer thickness that fills this gap snugly without exerting extreme pressure.
Do I need to glue these in place?
Usually, the weight of the glass and the window glazing tape or sealant provide sufficient friction to hold the packers in place during standard installation.
Are these suitable for timber frames?
Yes, these packers can be used with various frame materials, including timber, uPVC, and aluminum.
Troubleshooting
Glass unit remains loose after installation
Re-evaluate the gap width and replace with a thicker packer or add additional shims to achieve a firm fit.
Window sash is difficult to open or close
Check if the packers are correctly positioned at the corners to support the weight of the glass; realign if necessary.
Pros and Cons

- Manufactured to precise dimensions for consistent alignment

Setup, Compatibility & Care
To use these packers, first measure the gap between the glass edge and the window rebate. Select the appropriate thickness to ensure a snug fit without excessive force that could crack the glass. Ensure the frame surface is clean and free of debris before inserting the packers. While these plastic components are maintenance-free once installed, it is recommended to periodically inspect windows for any signs of frame movement or glass shifting. If a window begins to rub or stick, it may indicate a need to adjust or replace the existing glazing packers.
