15x100mm Bridge Glazing Packers are designed to provide a raised support point inside the glazing rebate while helping maintain the frame’s drainage and ventilation paths. Bridge packers are typically used beneath flat glazing packers to create a level packing surface for the sealed unit. This helps installers position the glass correctly without blocking the channels that allow water to escape and air to circulate within the frame. With a 100mm length and 15mm width, BP15 bridge packers offer a slightly wider support surface than 12mm and 13mm bridge packers, while still remaining suitable for narrower glazing systems. Made from polypropylene, these packers provide firm, moisture-resistant support for professional glazing work across uPVC, aluminium, and timber frame installations. Why installers choose 15x100mm Bridge Glazing Packers: Creates a raised support surface inside the glazing rebate Helps keep drainage and ventilation routes open Designed for use beneath flat glazing packers 15mm width gives a little more bearing area than narrower bridge packers Suitable for window, door, conservatory, and curtain walling applications 5mm thickness provides consistent elevation for glazing support Polypropylene construction for reliable trade use These 15x100mm bridge packers are a useful choice when installers need a slim but slightly broader bridge packer for supporting flat packers and sealed units inside the glazing rebate. What the 5mm Thickness is Used For 5mm – Raised Packing Bed & Drainage Clearance Used to create a raised base for the flat packer while keeping the lower rebate area clear. Best for: Supporting flat glazing packers Raising the packing point inside the glazing rebate Helping maintain drainage and ventilation Supporting insulated glass units during installation Narrow-to-medium glazing channels requiring a 15mm bridge packer
