Step-by-step installation
Before you begin, unpack all components and verify that all panels, fixings, and the join pins are present. Contact us before installation if anything is missing — do not attempt to modify units on site.
The top panel must be installed first. Each side panel pins to the panel before it as the assembly is built up around the window opening.
Step 1 — Install the top panel onto the wall
The top panel must be installed first — this sets the geometry that every subsequent panel keys off. Fix through the wall mounting holes in the fixing flange. Confirm the panel is level before driving fixings home.
Fixings must penetrate a structural member capable of resisting the design wind load for the site. Fixing centres: 200mm. Fastener selection is the responsibility of the site engineer.
Step 2 — Insert pin halfway into the top panel
At the join point between the top panel and side panel A, insert the join pin halfway into the top panel. Leave it proud — it will engage the side panel in the next step.
Step 3 — Join side panel A to the top panel
Locate side panel A onto the protruding pin to engage the joint between the two panels. Bring the panels together flush.
Step 4 — Fully insert the join pins
Drive the pin fully home from the top panel through into side panel A. Then insert the second pin from side panel A back into the top panel (side face). Both pins fully seated before fixing to the wall.
Step 5 — Fix side panel A to the wall
Fix side panel A through its wall mounting holes. Check the panel sits flush against the wall before driving fixings home.
The 90mm fixing flange seats against the wall surface; do not pack out or shim away from the substrate as this reduces the effective moment connection.
Step 6 — Repeat for side panel B, then bottom panel
Work the same sequence for side panel B (pin engagement → wall fix), then finish with the bottom panel. Inspect all faces for flush alignment, square corners, and secure fixings before sign-off.
Common mistakes to avoid
- Installing in the wrong order — the top panel must be installed first; every other panel keys off it
- Driving fixings home before pins are fully seated — the joint relies on full pin engagement before the panel is locked to the wall
- Installing before the window frame is confirmed plumb — the shroud will only look as good as what it's fitted to
- Storing flat panels in wet conditions before installation — keep them dry and stacked flat
- Packing out or shimming the fixing flange away from the wall — this compromises the structural connection that the wind classification relies on
- Substituting fasteners without engineering review on commercial or wind-exposed sites
Site responsibility
Site-specific wind classification and the suitability of the structural member to which the shroud is fixed remain the responsibility of the customer and the site engineer, consistent with industry practice.
For commercial projects above N3 wind classification, or where additional engineering documentation is required for facade approvals, contact our team before specification.
Installation time
Most four-sided units can be assembled and installed by two people in under 30 minutes. Three and two sided units are faster. Custom designs may take longer depending on configuration.
Engineering drawings available on request
Full engineering drawings, fixing patterns, fastener schedules, and project-specific structural documentation are available on request for commercial and facade specification work.
