SD-23: Roof Panel Ridge Junction

What this detail covers

  • How SIP roof panels meet at the ridge line.
  • Typical use of ridge fillets/packing and PU adhesive before fixing.

Key steps

  1. Confirm ridge support condition (steel beam/glulam/other) from the engineer’s drawings.
  2. Fit ridge fillets and packing timber as shown.
  3. Apply PU adhesive to the mating faces and fix to the specified schedule (subject to final engineering approval).

Checks

  • Ridge line is straight and panels sit tight at the correct angle.
  • Adhesive and fixing lines are continuous where specified.

Common mistakes

  • Fixing before panels are fully seated/aligned at the ridge.
  • Missing packing pieces that control alignment and bearing.

Indicative only: always follow the engineer’s fixing schedule and the project drawings.
