    PIANO-SYSTEM+I Pre-insulated polyurethane foam ventilation ducts

    PIANO-SYSTEM+I-The system of rectangular and round ventilation ducts, pre-insulated with polyurethane foam is an innovative solution for HVAC systems.The system of double ducts with a layer of polyurethane foam insulation guarantees the highest durability, prevents heat loss, prevents condensation of water vapour on the surface of the ducts and effectively suppresses noise emitted by the airflow.

    PIANO-SYSTEM+I ducts are covered with foam. As a result of a chemical reaction, the foam expands and tightly fills the entire space between the carrying duct and the outer casing pipe, ensuring the highest class of tightness available in ventilation - Class "D". It refers both to round and rectangular pipes. The results of the test performed proved that there is technically no air loss - actually, the loss is within the measurement error limit. Designers choosing PIANO-SYSTEM +I do not have to take into account air losses when selecting air handling units. PIANO-SYSTEM +I pipes integrity not only meets the highest requirements of European standards but even exceeds them!

    ✓ Prevention of condensation and moisture ingress
    Unlike other insulation materials, the polyurethane foam used to insulate the PIANO-SYSTEM +I system guarantees high resistance to water vapour diffusion, which prevents condensation and moisture penetration, which is the main cause of corrosion of pipes and ducts. The ducts can be installed outdoors - they are perfectly tight and rainwater cannot penetrate the insulation layer.
    ✓ No "thermal bridges"
    The foam structure makes the ducts more rigid, improves their resistance to high-pressure deformations caused by high pressure and eliminates the "thermal bridge" phenomenon that occurs in other insulation materials.
    There are no "thermal bridges" in the PIANO-SYSTEM +I ducts since they are fully covered with foam that expands to tightly fill all spaces between the inner pipe and the casing pipe.


    ✓ Excellent thermal insulation properties
    The PIANO-SYSTEM+I ventilation ducts have a thermal transmittance index more than twice lower than the generally used mineral wool, i.e. the foam layer can be over 50% thinner. Initial thermal conductivity of the foam
    is 10 °C EN 12667 W/m °K 0.020
    The thickness of the foam insulation layer is performed in the range of:
    • 10 mm - 50 mm for round ducts
    • 25 mm-100 mm for rectangular ducts
    ✓ Classification of reaction to fire
    They meet the requirements for building products. The ducts are non-flammable, non-drip and non-spreading fire. They do not fall under the influence of fire. B-s3, d0 in accordance with PN-EN 13501-1:2019-02
    ✓ Increasing the rigidity of the duct without the use of any internal steel bracing
    PIANO-SYSTEM+I ducts, because they are covered with foam which expands as a result of a chemical reaction and tightly fills all spaces between the inner pipe and the outer casing pipe, are extremely rigid and even the ducts with a side of up to 2000 mm do not have to be braced and still do not deform, which has been confirmed by ITB tests. In practice, the ducts with larger cross-sections and bracing may generate an increased level of noise due to expansion and contraction of the steel sheet and the bracing.
    ✓ Significant shortening of the project completion time and lower cost, as well as simple and quick installation
    Faster installation of the pre-insulated system by eliminating many stages of the conventional method including: Installation of ventilation ducts in the building; Welding pins with spacing; Welding or screwing special “Z” spacers to keep the appropriate distance from the insulation wool and to maintain the right angle to drain water; the direct on-site measurement of the sheet metal jacket constructed with appropriate overlaps and seams, and then its installation.
    All these works require additional time, appropriate weather conditions and qualified employees with many years of experience.
    Whereas PIANO-SYSTEM +I is a ready-made product that can be quickly installed in the building.
    ✓ Anti-corrosion - Durability of the coating
    Durability (the components are made of galvanised steel sheet):
    - weight of the zinc coating, g/m2> 275
    - zinc coating thickness, μm 20 (tolerance according to PN-EN 10346)
    No need to use an additional steel jacket, insulation and assembly pins, the welding of which weakens the surface of the sheet.
    PIANO-SYSTEM+I ducts do not need pins welded to the surface of the ventilation duct that would destroy the protective zinc coating or even burn a hole. Moreover, this method does not guarantee a tight adhesion of the insulation wool to the duct surface.

    • PERFORMANCE OF THE SYSTEM
      Tightness

      The pre-insulated AIRWENT SYSTEM ventilation ensures Class D tightness

      ROUND - according to PN-EN 12237:2005 WO-KOT/36/01, Ed. 2; Test conditions: -750 to 2000 Pa

      RECTANGULAR - according to PN-EN 1507:2007 WO-KOT/36/01, Ed. 2; Test conditions: -500 to 1000 Pa

      Strength

      ROUND - No permanent deformation or sudden change of tightness at the limit values of static pressure according to PN-EN 12237:2005 WO-KOT/36/01, Ed. 2; Test conditions: -750 to 2000 Pa

      RECTANGULAR- No permanent deformation or sudden change of tightness at the limit values of static pressure according to PN-EN 1507: 2007 WO-KOT/36/01, Ed. 2; Test conditions: -500 to 1000 Pa

      Zinc coating durability

      Due to the requirements for corrosion resistance, pre-insulated PIANO-SYSTEM +I ventilation ducts made of galvanised DX51D Z275 steel sheet, according to PN-EN 10346:2015 standard, have high durability and can be used in C1, C2 and C3 corrosivity atmospheres, according to PN-EN ISO 9223:2012.

      Fire classification

      Pre-insulated PIANO-SYSTEM +I ventilation ducts have been classified as B-s3, d0 reaction to fire class, according to PN-EN 13501-1:2019 and as non-flammable, non-drip and non-spreading fire from the building’s interior, according to the ordinance of the Minister of Infrastructure of 12 April 2002 (Journal Of Laws No. 75 of 12 April 2002, Item 690 as amended). At the same time, the products are classified as not falling during a fire. The above classification applies to pre-insulated PIANO-SYSTEM+I ventilation ducts mounted directly to components with reaction to fire classes A1 or A2, according to PN-EN 13501-1:2019 or at any distance from them.
