Standards and certifications
EN 12825 (2001) – Governs load, deflection, and testing methods. Topfloor applies a safety factor = 2 and a deflection ≤ 2.5 mm (Class A) for all panels.
LEED® – Panels contribute credits in Energy & Atmosphere, Materials & Resources, Indoor Environmental Quality, and Innovation in Design.
PSA/MOB (UK/Ireland) – Medium‑grade certification (static 4.5 kN, concentrated ≥ 3 kN) verified by BTL testing; Topfloor GW series meets the PSA specification.
ISO 9001, ISO 14001, ISO 45001 – Quality, environmental and occupational health management.
FSC® – Forest Stewardship Council certification for wood‑based cores.

Installation essentials
Step
Key actions
Material storage
Keep panels dry, sealed; temperature 5‑35 °C, RH 40‑70 %.
Site preparation
Subfloor dry (≥ 2 months after screed), clean, flat; all in‑floor services completed before floor lay.
Layout
Begin at the longest straight wall, maintain ≤ 600 mm offset from walls; use laser/spirit level; verify grid orthogonality.
Pedestal & crossbar fixing
Anchor pedestals (adhesive or mechanical); apply acoustic gaskets; for heights > 300 mm use crossbars (ST1/ST2/STH/50S).
Panel placement
Use suction cups; joint gap ≈ 1 mm; avoid corner pressure; lock panels (Corner‑Lock) where required.
Perimeter cuts
Use 55 × 60 cm or 15 cm strips; avoid very small pieces.
Finalisation
Install steps, ramps, closure strips; cover with protective film until hand‑over.
Time estimate
6 person crew ≈ 30 m² day⁻¹ (varies with access and panel type).
Following these steps ensures compliance with EN 12825 and PSA specifications.

Recycling programme: Panels are collected, refurbished, and re‑certified (cost ≤ disposal). The refurbishment loop follows a circular‑process diagram (New → Used → Renewed → New).
