22mm Flat Glazing Packers are durable plastic shims designed for accurate spacing, levelling, and support when fitting glazed units. With a 22mm width and 100mm length, these packers are useful where installers need a slightly wider support surface than 20mm packers, while still keeping a compact fit within the glazing channel. Made from polypropylene, they provide firm, non-compressible support under load and help keep sealed units properly positioned throughout the installation. Why installers choose 22mm Flat Glazing Packers: Helps level, space, and support sealed units Suitable for window, door, conservatory, and curtain walling installations Provides a practical support width for many glazing applications Non-compressible, durable, and moisture-resistant Helps reduce movement, misalignment, and uneven load points These packers are ideal for installers who need reliable everyday glazing packers for accurate unit positioning and consistent load support. What Each Thickness is Used For 1mm – Fine Adjustment & Final Levelling Used for small corrections where the unit is almost level. Best for: Final alignment adjustments Fine-tuning the position of glazed units Removing small gaps Minor corrections after main packing 2mm – Light Levelling & Small Gaps A useful thickness for slight spacing corrections. Best for: Small gaps Light levelling work Minor frame inconsistencies Small adjustments in glazing channels 3mm – Standard Everyday Packing One of the most commonly used thicknesses for general glazing work. Best for: Everyday glazed unit support Standard levelling tasks General spacing under sealed units Common installation adjustments 4mm – Moderate Gap Filling Used where a more noticeable adjustment is needed. Best for: Medium spacing corrections Supporting units in uneven openings Adjusting slightly misaligned frames General trade glazing work 5mm – Larger Adjustments & Load Support Provides stronger support where more spacing or lift is required. Best for: Larger gaps Heavier glazed units Stronger base support More significant levelling corrections 6mm – Maximum Spacing & Heavy Load Situations Used where the largest adjustment in this range is required. Best for: Large gaps or uneven openings High load-bearing points Base packing under frames Heavier sealed units
