36mm Flat Glazing Packers are extra-wide plastic packers designed for glazing jobs where a larger bearing surface is required beneath the glass unit. At 36mm wide and 100mm long, FP36 packers offer more contact width than 32mm and 34mm packers, making them useful for wider channels, larger glazed units, door sections, and curtain walling applications where stable support is important. Manufactured from polypropylene, these packers are firm, rot-resistant, and moisture-resistant. They help maintain the correct glass position during installation while providing reliable support under load. Why installers choose 36mm Flat Glazing Packers: Extra-wide 36mm profile for broad unit support Useful for larger sealed units and wider glazing channels Helps distribute support across a wider contact area Suitable for window, door, conservatory, and curtain walling work Strong polypropylene construction for stable packing These 36mm glazing packers are a practical option when the glazing channel allows for a wider packer and the installation requires a stable, even support point under the unit. What Each Thickness is Used For 1mm – Fine Height Correction Used when only a very small lift is needed to finish the alignment. Best for: Final unit positioning Fine levelling corrections Small gap adjustments Layering with other packers for precise height 2mm – Light Adjustment & Spacing Useful for minor corrections where a slim amount of extra support is required. Best for: Light packing work Small uneven areas Minor spacing under sealed units Fine adjustment in wider glazing channels 3mm – Everyday Wide Packer Support A useful general-purpose thickness for common installation work. Best for: Standard sealed unit packing Routine window and door installations General levelling work Controlled height build-up with multiple packers 4mm – Moderate Lift & Levelling Used when the unit needs a more noticeable adjustment during fitting. Best for: Medium gap filling Supporting wider glazed units Correcting uneven channels General trade glazing applications 5mm – Stronger Base Packing Provides a firmer lift for larger gaps or heavier units. Best for: Heavier sealed units Larger door or window sections Base support during installation More significant height corrections 6mm – Maximum Adjustment in This Range Used when the installation needs the thickest FP36 option for firm support and larger spacing. Best for: Deeper gaps below glass units Heavy-duty support points Larger glazing systems Raising units to the correct installed height
