Harmony between Nature and Humanit . A A commitment to well being and quality of living: Quality of life evolves from silence.

Environmental sustainability Construction materials need to be more and more Eco-Friendly to ensure the lowest environmental impact. Isolgomma has always used recycled raw materials, highly selected, to preserve the environment and quality of life. Isolgomma now operates in full compliance with EN ISO 14001 and OHSAS 18001:2007 standards. Isolgomma is member of GBC Italia organization and with its products which contain a minimum of 92% recycled materials, contributes to achieve the LEED® credits rate system. Acoustic insulation Isolgomma has been a leading company in the supply of sound insulations...

building Acoustic basics Sound is a molecular wave, produced by a sound source which is propagated in an elastic means with an oscillator mechanism to produce a pressure variation and a particle movement around an equilibrium point. The sound is propagated through the air (or other physical element) as a longitudinal wave. The sound velocity is a function of the air property and not from the frequency or sound wave shape. Sound from a pressure unit point of view involves 8 units of magnitude, from 0.00001 Pa up to 100 Pa. This wide range is not practical for acoustical analysis, evaluation and...

Acoustic Standards & Norms building EUROPEAN LAWS AND STANDARDS From a Technical point of view certain groups of ISO and EN standards govern the various calculation, measurements and testing situations ( e.g. ISO 140, ISO 717, EN 12354); while the performance indexes of the various building regulations are still governed by the national laws of each individual country. The following graphs shows the indexes as per the national laws of acoustic insulation levels for walls and floors for each country. From these we can see the variations in European insulation levels from country to country. Austria...

[ ] R’w DETERMINATION OF Rw INDEX FOR AIRBORNE SOUND INSULATION Rw and R’w according to ISO 717-1 The transmission loss index Rw, is the value in dB at 500Hz of the ISO curve 717-1 ( red curve) after the due translation. In fact the reference curve ISO 717 (red) must be moved up or down so that the yellow area have to be < 32 dB of the recorded curve. Unfavourable refuse + positive variation - negative variation Reference curve translate DETERMINATION OF Lnw INDEX FOR IMPACT SOUND LEVEL Ln,w and L’n,w according to ISO 717-2 The impact sound insulation index Lw, is the value in dB at 500Hz...

For thermal insulation means all systems and operations making up the efforts to reduce the heat flow of heat exchanged between the two environments at temperatures different. The thermal insulation in building construction is aimed, primarily, in order to contain the heat inside buildings. The interventions of thermal insulation in buildings are regulated by the provisions of the European Community, to which designers and applicators should refer. It is therefore appropriate to inquire in great detail about the requirements of the law and even more about the actual technical capabilities of...

building Isolgomma Laboratory Since June 2008 Isolgomma S.r.l. is equipped with an Acoustic Laboratory made according to ISO 10140 standards and suitable to conduct acoustic test for floor and walls. It had been designed and built in cooperation with Padua University following the latest rules of acoustics and building standards. Thanks to this news advance Laboratory the R&D Isolgomma department is able to perform the following tests: • Airborne sound insulation index for partition walls, floors and roofs. • Impact sound insulation index for standardized floor on reinforced concrete slab of 14...

FLOORS INSULATION

Floor insulation Floating screed A floating screed is the ideal solution for the impact sound insulation of any type of floor. This floor system is designed in order to obtain “mass” over the resilient layer which is acting as a “spring” to produce that mitigation effect. This floor system very efficiently reduces sound waves and vibration produced by walking, speaking or other sources. This is thanks to the floor system transforming all vibration and sound into micro movements of the upper floating screed. Under-Wall Strip: under any wall or partition a resilient strip is needed in order to...
