24mm Flat Glazing Packers

Type FP24 Glazing Packers are precision-moulded shims for 24 mm glazing systems — ideal for spacing, levelling, and supporting sealed glass units within uPVC, aluminium, or timber frames.

They ensure consistent alignment, even weight distribution, and a stress-free fit that prevents gasket damage, rattling, or deflection over time.

Each packer is manufactured from polypropylene, ensuring they remain stable and dimensionally true under load.

Why installers choose FP24 Glazing Packers:

• Keeps glazed units square, level, and properly supported
• Prevents edge pressure, cracking, or gasket distortion
• Non-compressible, weather-resistant
• Colour-coded by thickness for easy selection
• Compatible with uPVC, aluminium, and timber frames
• Ideal for windows, doors, and curtain walling systems

Built for accuracy, consistency, and long-term performance on every installation.
