Crossin® Wall Foam is a two-component spray polyurethane system used for the production of closed-cell rigid foam with self-extinguishing properties. The system consists of the polyol part (component A) and the isocyanate part (component B). Each of the ingredients is a viscous liquid and has different parameters. Component A with a higher viscosity is dark, while component B with higher density is brown. Both components are free of solid suspension. In addition, the system is distinguished by a reduced emission of volatile organic compounds (VOC), as it does not contain foaming agents that significantly deplete the ozone layer - according to European Union regulations, Regulation (EC) No. 1005/2009 of 16.IX.2009.

As a result of the combination and thorough mixing of both components, rigid (hard) foam is obtained. The system should b e processed only with professional high-pressure foaming units equipped with a foaming head. This product is a unique system designed for the production of high-quality thermal insulation, applied in both residential, commercial, as well as industrial and agricultural buildings. The system is characterized by increased flammability parameters (flammability class: E) and stable physico-mechanical parameters. Thanks to the appropriate thickness of the insulating layer (at least two uniform layers, which in total give a thickness of not less than 30 mm), the surface of the walls, partitions and facades is jointless, which significantly improves the energy efficiency of the whole building. Keep in mind that you must not exceed the recommended thickness of the total insulation (its maximum thickness is 35 mm).

Crossin® Wall Foam was introduced for sale on the basis of CPR Regulation No. 305/2011 together with the assessment of performance carried out by the Institute of Building Technology (ITB) 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 Crossin® Wall Foam system is used for the production of rigid (hard) foam, which at the same time is a sprayed thermal insulation applied directly to the insulated wall surface, partitions and façades, regardless of the building material used. If the foam is exposed to direct UV radiation (sunlight), it should be protected, e.g. by painting it with at least two layers of protective paint (in accordance with the recommendation of the manufacturer), of if necessary, secured with suitable waterproofing.

Main application advantages of the product:


  • Applicability directly onto the insulated surface made of most commercially available construction materials;
  • External and internal thermal insulation with a wide application range (insulation of walls, partitions and facades in residential, commercial, industrial and agricultural buildings, both modernized and newly erected);
  • Light, resistant to minor mechanical damage insulation allows the thickness to be chosen without overloading the building structure;
  • Low heat transfer coefficient allows for reducing the thickness of insulating material even by half in relation to the classic insulation materials;
  • Jointless insulation, without thermal bridges or air gaps responsible for heat losses;
  • The ability to isolate hard-to-reach places with full insulation tightness guarantee;
  • Speed of execution and versatile technique of applying insulation;
  • Thermal insulation with high resistance to moisture and wind protects the insulated object against mould and fungi;

Mechanical properties of polyurethane foam made from the Crossin® Wall Foam system:

  • Declared value, λD for thickness:
    • dN < 40 mm: 0,027 W/(m·K)
    • 40 mm ≤ dN < 60 mm: 0,025 W/(m·K)
    • dN ≥ 60 mm: 0,024 W/(m·K)
  • High mechanical strength, compressive strength: σ10 ≥ 270 kPa
  • Coefficient of water vapor diffusion resistance: μ 35 – μ 50
  • 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 the foam, perpendicular to the ground/tensile strength: ≥ 300 kPa
  • The content of closed cells: ≥ 90%

In order for polyurethane insulation to retain its properties over time, it is important to clean the insulated surface before spraying. It is also worth protecting the room and the immediate surroundings from possible dirt.
