26mm Flat Glazing Packers

26mm Flat Glazing Packers are designed for installers who need a strong, reliable packing shim with a slightly wider contact area than 24mm packers.

Measuring 26mm x 100mm, these packers are suitable for supporting sealed units, correcting uneven gaps, and helping maintain the correct glass position during installation. They are useful across a range of glazing, door, conservatory, and curtain walling applications where controlled spacing is important.

Manufactured from polypropylene, FP26 packers are rigid, moisture-resistant, and made to retain their shape under load. This makes them suitable for professional glazing work where long-term support and consistent thickness are important.

Why installers choose 26mm Flat Glazing Packers:

• Wider than 24mm packers for extra contact and support
• Useful for packing glazed units in windows, doors, and curtain walling
• Helps maintain correct glass positioning during installation
• Strong polypropylene construction for dependable load support
• Helps reduce the risk of uneven pressure points around the unit

These 26mm glazing packers are a practical option when you need a slightly wider flat packer but do not require the full width of a 28mm packer. The additional 8mm option also gives installers extra flexibility for larger gaps or heavier adjustment work.

What Each Thickness is Used For

1mm – Precision Packing & Small Corrections

Used where only a very small amount of adjustment is needed.

Best for:

• Final positioning of glazed units
• Fine gap correction
• Small alignment changes
• Combining with thicker packers for exact spacing

2mm – Light Spacing & Minor Levelling

A useful option for small gaps where a little extra support is required.

Best for:

• Slight unevenness in the glazing channel
• Light packing under sealed units
• Minor levelling adjustments
• Everyday fine-tuning on site

3mm – Regular Glazing Adjustment

A common middle thickness for standard installation work.

Best for:

• General glazed unit positioning
• Routine spacing and levelling
• Supporting units in typical glazing jobs
• Building up packer height when used with other thicknesses

4mm – Practical Medium Support

Used when a more noticeable correction is required without going to thicker packers.

Best for:

• Moderate gap filling
• Levelling units in uneven openings
• Supporting larger glazed sections
• General window and door fitting work

5mm – Stronger Packing for Larger Gaps

Provides more lift and support where the space under the unit is more substantial.

Best for:

• Larger installation gaps
• Heavier sealed units
• Base support during glazing
• Correcting more visible level differences

6mm – Heavy Adjustment & Base Packing

Used when a firm, thicker packer is needed for stronger support.

Best for:

• Significant spacing requirements
• Load-bearing support points
• Heavier glass units
• Uneven or deeper glazing channels

8mm – Extra Lift for Larger Spacing Requirements

The thickest option in this range, useful where a larger adjustment is needed.

Best for:

• Bigger gaps under glazed units
• Heavy-duty packing work
• Raising units to the correct position
• Applications where 6mm is not enough
