Flat glazing packers are used as setting blocks, location blocks, and spacing shims to support and position insulated glass units correctly within the frame. Bridge glazing packers create a raised support bed for flat packers while helping maintain drainage and ventilation paths in the glazing rebate. Wedge glazing packers are used to tighten glazed units, reduce movement, and assist with toe-and-heel adjustment on windows, doors, and opening sashes.

Which glazing packer should I choose?

Flat glazing packers – Best for general spacing, levelling, setting, and supporting sealed units within the frame.
Bridge glazing packers – Used underneath flat packers to create a raised glazing bed while helping keep drainage and ventilation routes clear.
Wedge glazing packers – Used for tightening glazed units, reducing movement, and making controlled toe-and-heel or sash alignment adjustments.
Multi-system bridge packers - Useful where a bridge packer is needed across multiple uPVC window systems.

Trade-Grade Window & Glazing Packers

Glazing packers help installers position, support, and adjust glass units correctly during window and door installation. They are commonly used when fitting insulated glass units, uPVC windows, aluminium frames, timber windows, doors, conservatories, and curtain walling systems.

Our range includes flat packers in multiple widths and thicknesses, bridge packers for drained glazing rebates, and wedge packers in a wide choice of taper sizes. Whether you need common stocked packers for immediate dispatch or specialist sizes for a larger job, GlazingPacker makes it easy to order or request a quote.

Glazing Packers – FAQs

Which thickness should I choose?

Choose the thickness that gives the correct glass position without over-compressing gaskets or seals. Many common glazing jobs use 1mm to 6mm flat packers, while bridge and wedge packers are selected based on the rebate depth, drainage layout, and adjustment required.

What is the difference between flat, bridge, and wedge glazing packers?

Flat packers provide direct spacing and support. Bridge packers create a raised support surface while helping keep rebate drainage clear. Wedge packers have a tapered shape and are used to tighten, stabilise, and adjust glazed units.

When will my order ship?
