There are many urban places and structures that require a high degree of acoustic insulation. Acoustic insulation is a term which describes the attenuation of sound passing between different spaces, or the reduction of echo within a specific space. The acoustic insulation level is important in places like classrooms, study halls and lecture halls, in places occupied simultaneously by a large number of people, inside private homes and in office workplaces and many other places.
In each one of these places, materials can be used which insulate the sound and help achieve a reduction in the volume of the sound passing between different parts of the same structure. To be able to improve acoustic insulation, various building materials can be used, where these can be applied in advance while the structure is still under construction, or they can be added after the fact in order to improve the insulation.
One of the most highly-recommended materials, which enables noise attenuation and acoustic insulation within and outside structures are the solid (glass-like) sheets from Plazit-Polygal, all of which are manufactured at the Company’s production site at Kibbutz Gazit in the Yizrael Valley. The sheets are manufactured from acrylic raw materials (PMMA) or polycarbonate (PC) at thicknesses of 10-20 mm. These are high-quality thermoplastic sheets capable of insulating noises in structures and within other urban spaces.
When is Acoustic Insulation Necessary?
Sound traveling between different rooms or homes in condominiums can be a severe nuisance. In places like schools, for example, where lessons are in progress concurrently, it is highly important that sound should not travel between the classrooms. In private homes as well, in offices and condominiums, if the acoustic insulation is deficient, it is possible to hear what is happening in other spaces, which can be a nuisance and even be a violation of privacy.
Besides that, in many public urban spaces, such as malls and public institutions, good quality acoustic insulation is required and the Plazit-Polygal sheets are used with great success to improve the acoustic insulation in these spaces.
Plazit-Polygal – Solid (Glass-Like) Sheets – Properties
The solid (glass-like) sheets from Plazit-Polygal are thermoplastic sheets made of Acrylic (PMMA) or polycarbonate (PC). Their thickness and solid structure, similarly to glass panes, coupled with the advantages of their being made of a plastic, high-elasticity material (in the acrylic form) and high mechanical impact resistance (in the polycarbonate form) while still retaining transparency and clarity close to that of glass.
Attenuation (dB) of an acrylic sheet, 15 mm thickness = 33 (dB)
Attenuation (dB) of an acrylic sheet, 20 mm thickness = 34 (dB)
Acoustic insulation is an important property in almost any kind of urban structure and especially in residential buildings and public structures. To achieve a high level of noise insulation.
For this, the Plazit-Polygal sheets provide an excellent solution both in terms of acoustic insulation and in terms of durability and suitability for use in construction.
