Composition and manufacture

The Styrozone® range’s closed-cell structure resists both moisture and water vapour ingress, problems which can be associated with open-cell materials. The upper facing of Kingspan Purlcrete® is a 10mm polymer fibre reinforced hydraulic cement, whilst the core is a high-performance rigid extruded polystyrene insulation. Kingspan Styrozone® and Purlcrete® have been manufactured and tested in accordance to ISO 9001:1994.

Size and weight

Styrozone® products N 300 R, H 350 R, N 500 R and N 700 R typical density is 30, 30, 35 and 45kg/m3 respectively. Purlcrete® products typical density 35kg/m3.

Strength

The compressive strength of Kingspan Styrozone® N 300 R, H 350 R, N 500 R and N 700 R typically exceed 300, 300, 500 and 700kPa respectively at 10% compression when tested in accordance to BS EN 826:1996. The compressive strength of Kingspan Purlcrete® typically exceeds 300kPa.

Effect of fire

Kingspan Styrozone® meets Euroclass E requirement to BS 13164:2001. Kingspan Purlcrete® has a FAA rating when tested to BS 476-3:1958.

Moisture properties

Styrozone® boards are highly resistant to water absorption. Boards are very resistant to the passage of water vapour and are unaffected by repeated freeze/thaw cycles. Purlcrete® is not sensitive to moisture of any kind. The boards achieve a resistance of greater than 825MNs/g when tested in accordance with BS EN 12086:1997.

Thermal properties

Thermal conductivity (λ value) of Kingspan Styrozone® N 300 R, H 350 R and N 500 R is 0.029W/mK (insulant thickness <120mm), 0.034W/mK (insulant thickness >120mm). Styrozone® N 700 R is 0.036 (insulation thickness <50mm). The thermal conductivity of the Purlcrete® polymer fibre reinforced cement topping is 1.4W/mK whilst the extruded polystyrene core is 0.029W/mK.
