⚠️ Important Before You Start
Ensure hangers are attached directly to the structural ceiling (concrete or steel beams) — not to unstable surfaces. First hanger from the wall: maximum 60 cm. Hanging from an unstable structure is dangerous!
Step-by-Step — How to Do It Right 👷
Step 1 — Measure and plan: Determine suspended ceiling height. Allow 10–15 cm below structural ceiling: 3 cm frame + 1.5 cm tile + hanger clearance.
Step 2 — Mark perimeter line: Mark a consistent line on all 4 walls at the planned ceiling height using chalk line and level.
Step 3 — Install perimeter angle (L-profile): Attach L-profile along all 4 walls at the marked line height. This supports edge tiles.
Step 4 — Hangers and main rails: Fix hangers into structural ceiling. First hanger: 60 cm from wall. Hanger spacing: 120 cm. Hang T24 main rails and level them carefully.
Step 5 — Cross rails: Clip cross rails perpendicular to main rails every 60 cm to create 60×60 cm cells.
Step 6 — Place Rockfon tiles: Start from center! Place 60×60 cm tiles into cells — no force needed, just lay them on the rail flanges. Leave empty cells for ventilation and lighting. Cut edge tiles with sharp knife.
💡 Pro Tip
Before cutting an edge tile — measure from the last full tile, not from the wall. Walls are rarely perfectly straight. Accurate measurement prevents waste and double-cutting.
