Data for natural frequency, deflection and impact sound improvement

We have performed measurements for deflection and natural frequency with 25 and 50 mm Sylodyn installed in Granab Subfloor System 9000. ÅF-Infrastructure AB has carried out measurements on our behalf in test rigs for vibration insulation. The results were presented in the report titled “Measurements of natural frequency and static deflection of Granab 9000”. The report supports the calculation models used for the Granab Subfloor System 9000, and detailed data were presented for each pad subjected to varying loads. SP performed laboratory testing with respect to impact sound improvement.
