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.

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. The R-values Technopol has always published for PolyCool and SuperCool are IN-APPLICATION system values: they already contain the surface resistances and the roof void. If you are building the assembly up yourself, use the board-only R and add your own surface films - otherwise you will count them twice and overstate the roof.
