    Disclaimer. Indicative estimate for early take-off and comparison only — not a construction schedule, structural design or fire rating. Panel counts assume simple runs; add for cutting waste, openings, end-laps (150 mm min) and non-rectangular geometry. Cover widths, R/U values, StoneWool panel weights and per-support fastener rules are taken from Technopol LiteSpan brochures / CAD details; EPS panel self-weight, PIR panel data and any fire-resistance rating are not established in those sources and are flagged above — confirm with Technopol before ordering. EPS is combustible; the only current reaction-to-fire claim on FR EPS is SANS 53501-1 Class B-s1,d0 (not a fire-resistance rating). © Technopol SA (Pty) Ltd · Leaders in EPS since 1993 · info@technopol.co.za · www.technopol.co.za · (011) 363-2780/1/2
