PREDICTION OF IMPACT SOUND FOR LIGHT WEIGHT FLOORS

INSUL can now predict the impact sound insulation of light weight floors. This is a very significant development from previous versions of INSUL which were capable of predicting impact sound insulation for massive floors such as concrete.

Impact sound insulation predictions can now be carried out for different joist constructions including timber joists and ZGirts. The prediction routines are sensitive to the dimensions of the joists, their mass and spacing and all of these variables can be set independently in INSUL. A range of floor linings is available including plywood, particle board, orientated strand board (OSB) and thin timber floor boards.

As with previous versions of INSUL, ceilings can also be included in the predictions, with a range of ceiling connections including directing fixing to the joists, rubber isolation clips and separate ceiling joists. INSUL also includes the option to add infill material in the cavity of the construction. See examples of prediction accuracy. click here to enlarge image

 

SOUND INSULATION OF SANDWICH PANELS

INSUL can now predict the sound insulation of a variety of light weight sandwich panels. A typical example would be panels with thin steel or aluminium skins, with a polystyrene or mineral wool core. For instance panels from Kingspan or Paroc. The sound insulation both of single panels and panels used in more complex constructions can be predicted. The properites of the core can be adjusted using the in built materials properties editor.

In addition sandwich panels with much stiffer cores can also be predicted, a typical example would be a panel with steel facings and a light weight aerated concrete (Speedwall). See example of prediction accuracy

TRAPEZOIDAL PROFILED METAL PANELS

INSUL has improved the prediction of profiled metal panels, typically used for commercial and industrial buildings. Previously only single panels could be predicted, and not complex constructions using corrugated or profiled panels. New routines based on the work of Lam and Windle in England allow more accurate prediction of particular profiles, and of constructions using profiled panels in conjunction with flat sheets and in cavity constructions as well. For instance the effect of a layer of plywood underneath a profiled steel skin can be predicted. Then this can be extended by adding an airgap and a second lining, with or without an acoustic blanket in the cavity.

POROUS BLANKETS AND FACINGS

INSUL can now predict the sound transmission loss of porous blankets either alone or as a facing for a construction. Typical constructions would include modular panels for acoustic enclosures that have a steel skin with a mineral wool infill and perforated steel internal facing.
