34mm Flat Glazing Packers

34mm Flat Glazing Packers are wide-profile plastic packers made for glazing applications where extra bearing width is useful during installation.

Measuring 34mm x 100mm, FP34 packers provide a larger contact surface than 30mm and 32mm flat packers. This makes them suitable for wider glazing channels, larger sealed units, and situations where the installer wants the load to sit across a broader support area.

Made from polypropylene, these packers are strong, rigid, and resistant to moisture. They help keep the glass unit correctly positioned while reducing the risk of movement, rocking, or uneven support during fitting.

Why installers choose 34mm Flat Glazing Packers:

• Extra-wide 34mm support face for larger glazing applications
• Helps create a stable base beneath sealed units
• Useful where 30mm or 32mm packers are not wide enough
• Suitable for window, door, conservatory, and curtain walling work
• Rigid polypropylene material for reliable long-term support

These 34mm glazing packers are a good choice when the installation calls for a wider flat packer with multiple thickness options for fine, medium, or heavier spacing adjustments.

What Each Thickness is Used For

1mm – Final Setting & Precision Adjustment

Used for very fine correction after the main packer height has already been built up.

Best for:

• Small finishing adjustments
• Fine unit positioning
• Correcting slight unevenness
• Layering with thicker packers for exact height

2mm – Light Packing in Wide Channels

Useful when a small amount of lift is needed without making a major height change.

Best for:

• Light spacing work
• Minor levelling corrections
• Small gaps under sealed units
• Fine adjustment in wider glazing channels

3mm – Standard Support for Regular Fitting

A practical thickness for everyday glazing and installation work.

Best for:

• General sealed unit support
• Routine window and door glazing
• Standard levelling work
• Building up height in controlled layers

4mm – Mid-Range Gap Filling

Used where the unit needs a moderate lift or where the support surface is slightly uneven.

Best for:

• Medium gap correction
• Aligning larger glass units
• Supporting units across wider channels
• Everyday trade installation adjustments

5mm – Larger Lift & Firmer Base Support

Provides a stronger height adjustment for installations where more packer depth is required.

Best for:

• Larger gaps beneath glazed units
• Heavier window or door sections
• Base packing before final setting
• More substantial levelling corrections

6mm – Thick Support for Bigger Adjustments

The thickest option in this range, useful when a firm packer is needed to raise or support the unit more significantly.

Best for:

• Deeper glazing channels
• Heavy-duty support areas
• Larger sealed units
• Significant spacing or levelling requirements
