Vibration Absorption and StructureBorne Sound Insulation
The material Regufoam® achieves toplevels in vibration absorption andinsulation of structure-borne noise.This material is a hydrolysis-proof androt-proof polyurethane foam that ismanufactured in six different gradesaccording to firmness. These differentdegrees of hardness are colour-labelled to prevent confusion. Selection form amongst the differenttypes depends on the load involved.They are available in standard
thicknesses of 12 and 25 mm and combinations thereof. Regufoam®
shows very low intrinsic frequencylevels within the relevant load ranges,resulting in high noise insulationvalues. Another advantage of thisinsulation material is its relatively lowcompression ratio, combined withenormous resilience. Regufoam® canbe used in a wide variety of applications. The material is usedwherever structure-borne sound and
vibrations require highly effectiveinsulation. This includes the fields ofstructural and civil engineering andtrack-laying. Regufoam® also plays animportant role in mechanical engineering and shipbuilding. Thestandard supply form for this materialis in rolls. Stamped parts, cutouts produced with a water jet and mould-formed articles are also available onrequest.
Fields of application
Road construction
In track-laying and tunnel construct-ion, as well as in road and bridge construction, BSW materials are usedto damp vibrations and to protectstructures from damaging vibrations.
Foundations
Buildings with load distribution platesrest on Regufoam® to protect themagainst ground vibrations.
Load Ranges
Structural engineering
Whether in lift motors, pumps, ventilation systems or block-type thermal power stations, Regufoam® iseasy to install and has a long useful life.
Industry
In industrial applications, Regufoam®
is used for active insulation of machinesand passive insulation of floor plates onwhich fine measuring equipment isinstalled, in laboratory rooms and inmeasuring booths. Both sub-critical andhyper-critical mounts are possible.
Standard sizes, on stock:
Thickness:12 and 25 mmOther thicknesses possible.
Rolls:width 1,500 mmlength 5,000 mmSpecial lengths possibledie-cutting, water-jet cutting,self adhesive possible.

Regufoam® is the material from which BSWGmbH manufactures a wide variety of materials for vibration damping as well as insulation and protection stripping for the construction industry. Regufoam® consists ofpolyurethane foam. Regufoam® products are
highly adaptable, have a long useful life, canbear high-level loads and are 100% recyclable.Object-specific, individual production as well as customer-specific finishing, packaging and storage ensure rapid, application-specific solutions.
Also in the BSW product programme: Regupol®
The expanded product spectrum for vibrationdamping with Regupol® includes Regupol®
types characterized by different load bearingcharacteristics. Regupol® vibration insulationconsists of a number of different polyurethane-bound rubber granulates that effectively coverload ranges from 0.01 to 1.5 N/mm2 in six different material types. The Institute for Structural Dynamics at Dresden Technical
University has carried out extensive studies ofthese material types.Regupol® has been known for many years forits homogeneity and as a reliable product inthe field of vibration insulation. With theexpanded product spectrum and coverage of higher load ranges, BSW is now upgrading its competence in the area of vibration technology.
