20mm Flat Glazing Packers

Flat Glazing Packers – 20 mm are designed to deliver reliable spacing and support when fitting 20 mm glass units into window and door frames. They help installers achieve a level, balanced installation while reducing stress on glass edges, seals, and frames.

The flat profile creates a solid bearing point beneath the sealed unit, ensuring weight is distributed evenly across the frame. This helps prevent movement, rattling, or distortion during installation and throughout the life of the unit.

Produced from polypropylene, these packers retain their exact thickness under load. The colour-coded system allows installers to identify sizes instantly, improving speed and accuracy on site.

Key advantages:

• Provides stable, even support beneath sealed units
• Helps maintain correct glass positioning and alignment
• Reduces risk of edge damage, movement, or noise
• Rigid construction for dependable load support
• Colour-coded thicknesses for quick on-site identification
• Suitable for uPVC, aluminium, and timber frames
• Ideal for windows, doors, and conservatory installations

Used by professional glaziers and installers, these packers offer a clean, efficient solution for consistent results across everyday glazing projects.

1mm Glazing Packers

1mm packers are used for very fine adjustments where only minimal spacing is required. They are ideal for final alignment, helping achieve a precise fit without putting pressure on the glass or surrounding frame.

2mm Glazing Packers

2mm packers provide light spacing and are suitable for minor levelling corrections. They are commonly used in standard installations where a small lift is needed to bring the unit into alignment.

3mm Glazing Packers

3mm packers are a popular all-round choice for everyday glazing work. They offer balanced support and spacing, making them suitable for most window and door installations.

5mm Glazing Packers

5mm packers are used where larger gaps need to be filled or where additional support is required. They are ideal for heavier units or frames that need more significant levelling during installation.
