Insulated ceiling systems for poultry houses and agricultural buildings.
Kit queued
PolyCool and SuperCool are Technopol SA composite insulated-ceiling boards — a fire-retarded expanded-polystyrene (EPS) core faced with a washable finish (PolyCool: white vinyl foil; SuperCool: 1 mm white uPVC, tongue-and-groove) — fixed below-truss, over-purlin or across-beam so each board serves as roof insulation and finished ceiling in one element.
| Property | Value | Standard |
|---|---|---|
| Product build-up | PolyCool: white vinyl foil laminated to one face of a fire-retarded EPS core. SuperCool: 1 mm white uPVC sheet laminated to one face of a fire-retarded EPS core, tongue-and-groove edges. Faced one side (both sides available). | — |
| Thermal resistance R-value (in application, by board thickness) | PolyCool (18 kg/m³ core): 1.27 @35 / 1.69 @50 / 2.40 @75 / 3.00 @100 mm. SuperCool (15 kg/m³ core): 1.60 @50 / 1.87 @60 / 2.30 @75 / 2.95 @100 mm m²·K/W | — |
| EPS core density (grade) | PolyCool standard 18; SuperCool standard 15; 20 or 30 optional for special insulation/mechanical requirements kg/m³ | — |
| Reaction to fire — composite board (SANS 428) | PolyCool: B / B1 / 2. SuperCool: B / B1 / 2 / H — 5-yr test validity lapsed; reconfirm | SANS 428 (via SANS 10177-10 / -11) |
| Reaction to fire — FR EPS core (Euroclass) | Class B — B-s1,d0 | SANS 53501-1 (EN 13501-1) |
| Areal mass (uncut board) | PolyCool (18 core): 0.35 + thickness_mm × 0.018. SuperCool (15 core): 1.0 + thickness_mm × 0.016 kg/m² | — |
| Board dimensions (thickness / width / max length) | PolyCool: 35/50/75/100 thick, width 600 or 1200 (±5), length up to 6000. SuperCool: 50/60/75/100 thick, width 1200, length up to 7500 mm | — |
| Maximum support spacing (over-purlin) | PolyCool by thickness: 1200 @35 / 1350 @50 / 1500 @75 / 1800 @100 mm board. SuperCool: 1400 (max recommended) mm | — |
Density is grade-dependent: 20 or 30 kg/m³ cores are available on request. Published R-values apply only to the standard density shown (PolyCool 18, SuperCool 15). Thermal conductivity (λ) is not published; figures are in-application R-values (m²·K/W). Back-calculating the legacy 15-density board-only U-values gives λ ≈ 0.037 W/m·K, but this is derived, not a stated value. Fire scope: composite-board classes are from FIRELAB tests FTC 17-104 (PolyCool, SANS 10177-10, 2017) and FTC 16-208 Rev.1 (SuperCool/Supacool, SANS 10177-11 horizontal, 2016), each on one specific tested build-up. Both certificates carry a 5-year validity and have lapsed (2021/2022) unless revalidated. SANS 10177-5 'B combustible' was declared, not tested. These are reaction-to-fire results only — no fire-resistance rating (REI/FRR) is established for either board; determine FRR to SANS 10177-2 where required. Under sustained fire SuperCool's uPVC facing softens, ignites and can shed flaming/molten droplets (agricultural classification; may affect sprinkler operation). Euroclass B-s1,d0 was measured on the bare FR EPS core (60 mm, ~18.4 kg/m³) and does not represent the faced composite board. Fire-test validity: the composite-board classes from FTC 17-104 (2017) and FTC 16-208 (2016) have passed their 5-year FIRELAB validity; revalidation is required before reliance. The SANS 10177-5 ‘B (combustible)’ descriptor is a declared class, not a test result.

Each figure is labelled with how we know it — a named in-validity test, a supplier value, an in-house calculation, or a test whose validity has expired.
