Product Information
Full details
WEMNO Glazing Packers in 5mm blue are essential precision tools for professional window and door installers, as well as DIY enthusiasts looking for reliable structural alignment. These durable spacers effectively manage the weight of heavy glazing units, preventing frame distortion or sagging over time, though they are specifically sized at 28mm long and may require combining with other sizes for complex, non-standard gaps.

FAQs
Can I use these outdoors?
Yes, they are completely rot-proof, waterproof, and unaffected by exposure to the elements.
Are these packers compressible?
No, they are designed to be rigid to ensure the frame weight is supported without settling over time.
Do I need to glue them in place?
While they are usually held in place by the weight of the unit and the frame fixings, a small amount of sealant can be used to hold them steady during the installation process.
Are they compatible with timber frames?
Yes, they are suitable for use with uPVC, aluminium, and timber frames.
How do I know which color corresponds to which thickness?
WEMNO uses a color-coded system; the blue version is specifically 5mm, while green is 1mm and grey is 4mm.
Troubleshooting
The frame is still not level after inserting the packer
The gap may vary across the length of the frame; use multiple packers of different thicknesses at various points to achieve a perfect plane.
Packer keeps sliding out during installation
Apply a small dab of low-modulus silicone to the packer before insertion; this will act as a temporary adhesive until the frame is fixed.
Pros and Cons
Pros
- Resistant to compression and perishing
- Waterproof and rot-proof for external use
- Versatile for general construction shimming
- Standardized color-coding for easy thickness identification
Cons
- Specific 28mm length may not fit all wide-profile frames
- Fixed 5mm thickness requires additional sizes for varying gaps
- Cannot be adjusted once the frame is fully sealed in place
Setup, Compatibility & Care
To use the WEMNO Glazing Packers, first assess the gap between your frame and the opening using a spirit level. If the gap exceeds 5mm, you may need to stack these with other WEMNO variants or combine with different thicknesses to reach the required dimension.
Place the packers at the load-bearing points of the unit—typically under the corners and at intermediate mullions—to distribute weight evenly. Once in position, ensure they are securely pinned or held by the frame weight before applying silicone or expanding foam. No specific maintenance is required post-installation, as the material is chemically inert and designed to remain permanently in the wall structure.
