Ekoprodur®S0541 Polyurethane system

As a result of the combination and thorough mechanical mixing of both components, rigid (hard) foam with a closed-cell structure is obtained. The system should be processed only with the use of high-pressure foaming units equipped with foamer heads. This product is a unique system designed for the production of high-quality thermal insulation, applied mainly outside buildings, both residential, commercial, as well as industrial or agricultural. In addition to the increased compressive foam strength, enabling long- and short-term structural load, the system is characterised by increased flammability parameters (flammability class: E) and physico-mechanical parameters that remain unchanged over time. Due to the appropriate thickness of the insulation layer, which additionally is jointless, the energy efficiency of the entire insulated surface is improved.

EKOPRODUR S0541 was introduced for sale on the basis of the Regulation on construction products CPR No. 305/2011 along 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 S0541 system is used for the production of rigid (hard) foam, which at the same time is a spray thermal insulation applied directly to the surface of the roof, floor or foundations regardless of the building material from which they are made.

Main application advantages of the product:

•  Applicability directly onto the insulated surface made of most commercially available construction materials;
• External thermal insulation with a wide application range (insulation of roofs, floors, foundations in residential, commercial, industrial and agricultural buildings, both modernized and newly erected);
• Extremely durable and light insulation allows individual insulation thickness to be chosen without overloading the building structure;
• Jointless insulation without thermal bridges or air gaps responsible for heat loss;
• The ability to isolate hard-to-reach places with full insulation tightness guarantee;
• Speed of execution and versatile technique of applying insulation give the possibility of making insulation in a single day - in case of a flat surface of up to 1000 m² ;
• Thermal insulation with high resistance to moisture and wind protects the insulated object against mould and fungi;
