Now available in INSUL Release 9.0.24: Stravigym and Stravifloor frames and floor coverings
Entity view (Content)
INSUL, distributed by Marshall Day Acoustics Ltd, is a program for predicting the sound insulation of walls, floors and ceilings.
Acoustical consultants can use this online tool to quickly evaluate new materials and systems, as well as investigate the effects of changes to existing designs.
INSUL has been on the market for more than 20 years and is available in many languages. The software has been considerably improved over time. New updates are regularly released, concerning both the user interface and the accuracy of the data for a wide range of constructions through continuous comparison with laboratory tests.
INSUL is particularly useful for making good estimations of the Transmission Loss (TL) and Impact Sound (Ln) in 1/3 octave bands and Weighted Sound Reduction Index (STC or Rw) or Impact Rating (IIC/LnTw) for use in noise transfer calculations, allowing its users to confidently specify solutions that will meet the desired sound insulation.
The software draws information from two material databases, the Custom Database on the one hand, which is only visible to the local user and contains own materials, and the INSUL Database on the other hand, which is available to everyone and cannot be edited by local users, lists items for modelling.
Over the years, CDM Stravitec regularly added floor systems to the Custom Database. Stravifloor Mat solutions that can be used as floor coverings and a frame based on discrete supports were listed in the INSUL Database.
The recently released INSUL 9.0.24 update comes with even more Stravifloor and Stravigym frames and types of floor covering. Acousticians from all over the world are now able to use this predictive software to design various types of floating floor systems, such as Stravifloor Jackup-R system with high resilience natural rubber elastomeric pads or springs as the frame, or lightweight Stravifloor Mat and Stravigym systems as floor covering.
