Steel-faced insulated panels — EPS, PIR or stone-wool core — for insulated ceilings and internal walls. Ceiling boards are also available as NuClad (white Chromadek-faced EPS composite, tongue-and-groove).
Kit complete
LiteSpan is Technopol's factory-laminated composite sandwich panel — two coated-steel (Chromadek) skins bonded with PU adhesive to an insulating core — supplied in two core families (FRCel fire-retarded EPS and non-combustible Stone Wool) as double tongue-and-groove interlocking wall and ceiling boards.

| Build-up | Composite sandwich: two coated-steel (Chromadek) skins + PU adhesive over insulating core; double tongue & groove interlocking. Two core families: FRCel fire-retarded EPS and resin-bonded Stone Wool | — |
| Core thermal conductivity (λ) | FRCel EPS core 0.0352 (λ_declared); Stone Wool core ≤0.035 W/m·K | SANS 54509 / TS EN 12667 |
| Core density | FRCel EPS core ~21 (measured apparent, tested panel); Stone Wool core 120 kg/m³ | SANS 54509 / TS EN 1602 |
| Core compressive strength (10% deformation) | FRCel EPS core 110 (=0.110 MPa); Stone Wool core ≥45 kPa | SANS 54509 / TS EN 826 |
| Reaction-to-fire class | EPS panel B/B1/2/H; Stone Wool core A1 (non-combustible) | SANS 10177-11 / TS EN 13501-1 |
| Fire-resistance rating (Stone Wool assemblies) | 100 mm wall: FR60 (fixed joint) / FR30 (unfixed joint); double-studded firewall (±195 mm): FR120 — all non-load-bearing — 5-yr test validity lapsed; reconfirm minutes | SANS 10177-2 |
| Panel dimensions | EPS board: thickness 50–120, cover width 480 / 1140, length ≤6000; Stone Wool wall: cover width 1145, core 50 / 75 / 100; steel skins ≥0.5 mm | — |
| Applicable standards | SANS 10177-11 & -10 (reaction-to-fire), SANS 10177-2 (fire resistance), SANS 54509 (sandwich-panel ITT); TS EN 826/1602/1607/12667/13501-1 (Stone Wool) | — |
EPS core density (~21 kg/m³) is the measured apparent core density of the tested 125 mm 990 IBR panel (SANS 54509 ITT, report OTH-T-2309-04); a declared EPS grade/density range for the ceiling/wall boards was not found in a primary Technopol datasheet — grade-dependent. EPS reaction-to-fire class B/B1/2/H is a SANS 10177-11 flame-propagation result (FIRELAB FTC 19/117) covering thicknesses ≤120 mm provided the panel end is encapsulated in mineral wool; it denotes reaction-to-fire only, NOT a fire-resistance rating. The EPS core is combustible: panel ends must be folded up ~10 mm at perpendicular joints, and it cannot be used with recessed/downlighter fittings. Fire-resistance ratings apply only to the tested Stone Wool assemblies: 100 mm non-load-bearing wall FR60 (fixed-joint) / FR30 (unfixed-joint) per FTC 20/011, and the ±195 mm double-studded firewall FR120 per FTC 20/119 (both SANS 10177-2, non-load-bearing). They do NOT extend to the EPS panels or to other build-ups/thicknesses. FIRELAB test reports are valid 5 years or until a change to product composition, manufacturing process or approved supplier (FTC 18/284, 19/117, 20/011, 20/119). Fire-rated Stone Wool fixings must be steel (not aluminium), steel angles/channels ≥1.6 mm, rivets stainless steel. Fire-test validity: the cited FIRELAB reports (FTC 18/284, 19/117, 20/011, 20/119) have passed their 5-year validity as of 2026; revalidation is in progress — confirm the current certificate before relying on these ratings.
