Spacing and design basis
The conditions the tile manual sets for the full 1.5 m hook spacing.
| Condition | Portrait, landscape and adjustable hooks |
|---|---|
| Maximum hook spacing | 1.5 m, following the truss spacing |
| Roof height | Up to 10 m |
| Roof tilt | Up to 25° |
| Roof zone | Zone H |
| Terrain category | Designed for C. Factors for A (90%) and B (95%) |
| C4 site | Reduce spacing by 5% |
| Rail end overhang | Up to 40% of the last span |
| Gap between modules | At least 18 mm down the slope |
- Roof slopes 0° to 30° and installation heights up to 20 m; outside these, a project-specific engineering certificate is needed.
- Outside these limits, reduce the spacing and confirm it with Lumasol before installing.
- Rails must sit within the module's clamping zones; take them from the module manufacturer's manual.
Installation
The sequence from the Lumasol manual, for the portrait hook. The manual is the reference on site.
Step 1: Plan the layout
- Confirm the wind region, terrain category, ISO 9223 class, roof height and slope (0° to 30°).
- Allow at least 18 mm between modules down the slope.
- Set the hook spacing along the rail by the rafter spacing, no more than 1500 mm; set the rail spacing inside the module's clamping zones.
Step 2: Fix the hooks
- Remove the tiles at the marked positions, or push them up slightly.
- Fix each hook to the rafter with timber screws, at least 25 mm embedment: 3/8" hex socket, no more than 3,000 RPM.
- The hook must not press on the tile: raise it with a timber block if needed, and grind a recess in the tile above so it lies flat.
- Set the hooks out in a straight line. Never use a fitted hook as a step.
Step 3: Fit the rails
- Fix the rail to the hooks at 16 to 20 N·m once it is in position. With the height extender, fix hook and extender first, then the rail, both at 16 to 20 N·m.
- Join rails with the splice within ¼ span of a support, never over a support or at mid-span, at 16 to 20 N·m.
- Every rail is held by at least two hooks.
Step 4: Clamp the modules
- Fix the first module with an end clamp, lightly. Lift it slightly, slide in mid clamps with earthing clips, then place the next module.
- Earthing clips are single use. Tighten every clamp to 16 to 20 N·m once the modules are in their final position.
| Fixing | Codes | Torque |
|---|---|---|
| End and mid clamps | LMS-EC30-35-KIT-BP, LMS-IC30-35-KIT-BP | 16 to 20 N·m |
| Rail to hook | LMS-TH1-KIT, LMS-TH2-KIT, LMS-TH4-KIT | 16 to 20 N·m |
| Rail joiner | LMS-PRO-RAIL47-SP-KIT | 16 to 20 N·m |
| Grounding lug | LMS-EGL-KIT | 16 to 20 N·m |
| Adjustable hook height bolt | LMS-TH4-KIT | 33 to 40 N·m |
Stainless fasteners can gall. Apply force evenly along the thread, use power tools at low speed, and avoid impact drivers.

Technical questions
Does the hook rest on the tile?
No. The hook is fixed to the rafter with timber screws and must not press against the roof tile. If it is not high enough, raise it with a wooden block. Where needed, grind a recess in the tile that sits over the hook so the tile lies flat.
How are the hooks fixed?
Into the rafters with timber screws at a minimum 25 mm embedment, using a 3/8" hex socket at no more than 3,000 RPM. Never use fitted hooks as a step.
Which hook do I need?
Portrait rows use LMS-TH1-KIT and landscape rows LMS-TH2-KIT. The adjustable hook LMS-TH4-KIT adjusts in height from 56 mm to 83 mm, with the height bolt tightened to 33 to 40 N·m. A slate hook, LMS-SH1-KIT, is listed in the catalogue.
When can hooks be spaced at 1.5 m?
Roof height up to 10 m, roof tilt up to 25° and the array in roof zone H. Hook spacing along the rail follows the truss spacing and should not exceed 1500 mm. Outside these limits, reduce the spacing.
What roof pitch is covered?
Roof slopes from 0° to 30°. Outside this range a project-specific engineering certificate is required.
What about coastal sites?
SUS304 hooks and fasteners are warranted for 20 years in C1 to C4 and are not warranted in C5. In C4, reduce the interface spacing by 5%. Galvanised steel parts are warranted only in C1 to C3.
