After this course

What you'll be able to do yourself.

Water runs down the glass to the sill and hunts for gaps. Fire hunts for gaps at the slab edge. This course starts with sills, frames and sealant, then moves up to curtain walls: stick, unitized, spandrel and fire stop. You see every decision directly in the section.

  1. 1Detail a sill with fall, projection and drip groove.
  2. 2Size sealant joints and backer rod correctly.
  3. 3Choose frames, glass and sill beams for ordinary windows.
  4. 4Calculate aluminium frame movement and its allowance.
  5. 5Tell stick from unitized curtain wall in section.
  6. 6Detail the fire stop at the slab edge and the spandrel zone.

Good for

  • Drafters detailing windows and facades.
  • Junior architects coordinating with facade contractors.
  • Site supervisors on aluminium and glass work.

Slide the value. The drawing follows, just like in the lessons.

Whatever the gap, it must be closed with fire stopping so fire and smoke can't climb between floors.

    The parapet detail is simple but right on target. My senior asked where I learned it.

  • Yohana Simanjuntak

    Junior engineer

    Spot the Fault is addictive. Every drawing looks right until you check the membrane height.

  • Fikri Hidayat

    Drafter, 2 years in a studio

    Layer Stack made the waterproofing build-up stick in my head. It lands better than watching a video.
