Structural insulated roof panels — steel skin bonded to an EPS core, spanning purlin to purlin.
Kit complete
LiteSpan roof panels are a factory-laminated composite (sandwich): Chromadek steel skins bonded to a fire-retardant EPS core, giving sheet, insulation and finished ceiling in one lay. Available as the 990 IBR (exposed valley fix) and 990 Standing Seam (concealed clip) profiles.

Confirmed product spec (2026-07-12): standard thicknesses 50/75/100/120/150 mm; standard core FRCel EPS. The Standing Seam single-skin profile is 495/282 mm. Reaction-to-fire class is B-s1,d0 to SANS 53501-1 (Euroclass), FIRELAB report IT 24-06-00029, which tests the 150 mm LiteSpan panel (valid to 2029); the 60 mm FRCel EPS core also holds B-s1,d0 under IT 23-08-00009. This is the current classification and supersedes the older large-scale SANS 10177-11 ‘B/B1 to 120 mm’ listing (FTC 19/117), which has lapsed. Reaction-to-fire is not a fire-resistance (minutes) rating. R-values are installed system values (skins + surface films); 50 mm and 120 mm are computed from the ITT λ, the others brochure-confirmed. λ, mass and compressive stress are measured values from ITT OTH-T-2309-04 (125 mm 990 IBR, FRCel core). Load/span capacity is given by the LiteSpan load/span design tables (calibrated to the ITT); the older brochure span figures are superseded. No Agrément applies to LiteSpan (Agrément 2020/609 covers the LiteCore Building System only).
