Setting Blocks & Packers
Essential Glazing Setup & Support Systems
Glass doesn't install itself level, plumb, and properly supported. Setting blocks and packers are the unsung heroes of quality glazing work - the difference between installations that last decades and those that develop stress cracks, leaks, and alignment issues within months.
Setting Blocks
Engineered to carry glass weight without compression or degradation over time. Properly positioned setting blocks distribute loads evenly across the frame, preventing edge stress and bottom edge contact that leads to premature seal failure. Non-corrosive materials won't stain glass or react with sealants. Available in sizes to match your glass thickness and frame depth requirements.
Glazing Packers
Achieve precise clearances and maintain consistent edge cover throughout the installation. Our packer range gives you the fine control needed to level large panels, accommodate out-of-square openings, and ensure uniform sealant depth on all sides. Stackable designs let you dial in exact measurements without hunting for pre-cut sizes.
Edge and Face Packers
Purpose-designed for specific locations within the glazing system. Edge packers maintain critical clearances between glass and frame, while face packers provide lateral support without creating hard contact points. Color-coded options simplify selection on site and speed up installation when you're working with multiple glass thicknesses.
Why Proper Support Matters
Inadequate or incorrectly positioned support transfers stress directly into the glass and seal. Temperature movement, wind loads, and building settlement will find any weakness in your glazing system. Setting blocks and packers engineered for the job absorb these forces without compromising the installation.
Compliance with AS 1288 and glazing standards requires proper support. More importantly, your reputation depends on installations that don't fail.
Get the Details Right
Glass thickness, frame material, panel size, and exposure conditions all determine which blocks and packers you need. Our team understands glazing systems and can help you select the right support components for compliant, long-lasting installations.
Because cutting corners on affordable packers could be a waste of a thousand dollar glass panel.
