Trade-grade window & glazing packers (1–6 mm+)

Glazing packers provide consistent, non-compressible spacing for glass, sealed units and uPVC or aluminium frames. Our range covers common 1–6 mm thicknesses with recognised colour codes for quick identification onsite. Choose flat for general setting and levelling, bridge to span drainage/thermal breaks and protect gaskets, and wedge when you need fine adjustments that stay put. Next-day UK delivery available and VAT invoices included. Need help selecting sizes? Contact us for trade advice.
