MC026-06 Bracket and Fixing Design for Curtain Walling Systems
Enrolment open — Course starts 29 October 2026
Angle Brackets, Spigots, and the Hole Logic That Decides Everything — How Curtain Wall Mullions and Unitised Panels Are Fixed to the Building
About This CPD
This practical technical CPD covers the brackets and fixings that hold stick and unitised curtain walls to the building: the angle bracket and the spigot, the hole logic that decides which connection carries weight and which lets the mullion move, the arrangements used in practice, and the anchor in the narrow slab edge.
Presented by Eugene Korch (IAST), the course works from the organising principle — one fixed point per mullion section — through the loads, the eccentricity moment and the push-pull pair it creates at the anchors, to the full calculation sequence in one view. The course is released on demand and available from 29 October 2026.
This session covers:
The commercial lens, and why most of what a façade costs is decided before anything is built
Cost drivers at concept, including the wall-to-floor ratio, plan shape, floor plate, and storey height
Residential versus commercial façades, balconies, ventilation, and the balcony premium
Design decisions that move the rate, including panel repetition and unitised versus stick systems
The single-source trap, and what it costs in both pricing power and future repairs
The rate build-up, from materials and fabrication to transport, labour, and installation
Costs outside anyone’s control, including commodity prices, energy, inflation, and currency exposure
Margin versus mark-up, and why confusing the two can cost a contractor a fortune
Procurement, tendering, and the Pre-Construction Services Agreement, including how a contractor gets onto one
Using clear diagrams and real arrangements, this CPD focuses on the practical question behind every curtain wall connection: which bracket carries the weight, which lets the mullion move, and has the anchor been checked against the real slab edge?
What You'll Learn
Read the mullion structural model from the bracket arrangement
Apply the hole logic to decide which bracket carries weight and which restrains wind
Place movement joints correctly relative to the brackets
Collect the loads on a curtain wall bracket including the eccentricity moment
Understand unitised panel brackets and their movement behaviour
Verify anchors in narrow slab edges and know when cast-in channels are needed
Detail installation adjustment separately from in-service movement
Run the full bracket calculation sequence and catch the common errors
