EKOPRODUR S0310 / E is a polyurethane system consisting of a polyol part (component A) and an isocyanate part (component B). Each of the ingredients is a liquid and has different parameters. Component A is yellow to orange, while component B has a brown colour. Both components do not contain solid suspension. In addition, the system is distinguished by the lack of volatile organic compounds (VOC), as it does not contain foaming agents that significantly deplete the ozone layer - in accordance with European Union regulations, Regulation (EC) No. 1005/2009 of 16.IX.2009.

The system is foamed with carbon dioxide (CO2) produced in the reaction of component A with component B. The result of the combination and thorough mechanical mixing of both components is a semi-rigid foam (soft) with an open-cell structure. The system should only be processed using high-pressure foaming units equipped with a foaming head. This product is a unique system with increased flammability parameters, intended for the production of thermal insulation with acoustic properties. It should be applied only inside buildings in residential, commercial, public and industrial spaces, including hangars or media premises with low humidity. The system is characterized by physico-mechanical parameters that remain unchanged over time.

Spraying should be carried out so that the resulting layers are as thick as possible, even > 100 mm, while maintaining a constant humidity, which should not exceed 70% for the environment, and up to 15% for a porous substrate (non-porous substrate must be dry). The properly chosen thickness of the insulation, which additionally is jointless, improves the energy efficiency of the entire insulated surface. The material should not be exposed to direct UV radiation (sunlight) and have contact with moisture or water. In such situations, the insulation should be additionally protected.

EKOPRODUR S0310 / E was introduced for sale on the basis of the Regulation on construction products CPR No. 305/2011 together with the assessment of performance carried out by the Building Research Institute in accordance with the European harmonized standard PN-EN 14315-1. The product has the PZH hygienic certificate, as well as CE marking confirmed by the Declaration of Performance issued for this product.

The EKOPRODUR S0310 / E system is used for the production of semi-rigid foam (soft foam), which at the same time is a sprayed thermal and acoustic insulation applied directly on the insulated roof surface, attic, roof, ceiling, walls, including in wooden, masonry, steel and skeletal structures of residential, industrial and public buildings, regardless of the building material used.

Main application advantages of the product:

  • Can be directly applied onto the insulated surface made of most commercially available construction materials;
  • Internal thermal and acoustic insulation with a wide application range (both in modernized and newly erected buildings);
  • Incomparably light insulation that does not overload the building structure;
  • Jointless insulation without thermal bridges or air gaps responsible for heat loss;
  • The ability to isolate hard-to-reach places, especially slants and gaps in the case of attic insulation, with full insulation tightness guarantee;
  • The speed of execution and versatile technique of applying insulation give the possibility of making the whole insulation even in one day – the outer layer dries in about 13 seconds;
  • Thermal and acoustic insulation with high resistance to moisture and wind thanks to Bio Defence Technology additionally protects the insulated object against mould and fungi;

Mechanical properties of polyurethane foam made with the EKOPRODUR S0310 / E system:

  • Apparent density of the core: ≥ 7 kg/m3
  • Classification of the reaction to fire performance: E
  • Fire class: Bs1d03
  • Short-term water absorption by partial immersion, WP ≤ 0,85 kg/m2
  • Coefficient of thermal conductivity:
    • λmean, i : 0,037 W/(m·K)
    • λ90, 90 : 0,038 W/(m·K)
  • Declared value, λD for thickness: 0,038 W/(m·K)
  • High mechanical strength, compressive strength: σ10 ≥ 6 kPa
  • Coefficient of water vapor diffusion resistance: μ 3
  • Temperature stability:
    • 70°C, 90% RH, over 48 h: l ≤ 4%, w ≤ 4%, t ≤ 1%
    • -30°C, over 48 h: l ≤ 2%, w ≤ 2%, t ≤ 0,5%
  • Total relative deformation:
    • 48 h, 20 kPa, 80°C: ≤ 2,57%
  • Adhesion of foam, perpendicular to the ground: ≥ 20 kPa
  • The content of closed cells: ≤ 20%


In order for the foam to retain its parameters and ensure the best adhesion to the substrate, before starting work, clean the insulated surface of dust, oil, loose fragments and other agents that may affect the foam adhesion. In addition, it is necessary to secure the room and the immediate surroundings, mainly windows, doors, furniture, to avoid accidental soiling.
