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
