1 DIATHONITE PREMIX Eco-friendly cork based plaster for sound absorption and acoustic insulation

2 Diathonite Premix Factsheet Demonstration tests Diasen undertook the first series of tests on cork based plaster as early as 985. The aim of our research was to obtain a unique product that would have the best thermal, dehumidifying, sound absorbent and long lasting qualities (when exposed to cold/ heat and salt) with easy application. Durability of Diathonite Premix All the materials used to produce Diathonite Premix have a lifespan of centuries; archaeological findings have even brought to light remains of Roman houses dating back to as far as 2000 years ago, which were insulated with cork. The diatomaceous earth and clay, which form the basis of our product, have been accumulated in deposits for thousands of years on our planet. Binder based on natural hydraulic lime Cork Cork: the decision to use cork was based on its ability to perform as a finished material, adaptable to, and therefore efficient for, new construction developments. This material is non-toxic, biologically pure, unalterable, waterproofing, breathable, resistant, thermally inert, electrically neutral and non-deformable. It has a good mechanical resistance, low combustion speed and excellent acoustic performances. Clay: it is a natural porous and light material. It has a good thermal inertia and a good compression resistance, it is highly breathable and resistant to humidity. Natural hydraulic lime: it is a natural hydraulic binder with high breathability; it is an excellent thermal insulation and it is resistant to thermal shocks. It has an excellent adhesion on any kind of support. Diatomaceous earth: this is a naturally occurring mineral, formed through the accumulation of organic material in the ocean floor in prehistoric times. When the water receded, deposits were distributed in various parts of the earth. Due to its high level of porosity (85%) per volume, diatomaceous earth can absorb liquid of up to one and a half time its weight. Eco friendly additives: obtained by vegetal source, they enable the mix to amalgamate, making it more malleable and easier to apply. They give rise to the formation of micro cells, which maintain a high level of permeability to water vapour and increase the thermal resistance of the binder. Fibers: fibers are easily dispersed in the matrix constituting a homogeneous material able to counteract the plastic shrinkage and the formation of micro-cracks, consequently increasing its resistance. It gives mechanical resistance, a perfect stability over time and they do not release toxic residues. Technical analysis of components. 2.

10 Diathonite Premix Acoustic simulation of an Auditorium in a Cinema This report presents the results of acoustic simulations undertaken of a project of an auditorium in a cinema in Bangalore, India. Simulations have been performed using CATT Acoustic software, one of the most dedicated software used by academics, practitioners and acoustic consultants. 25Hz 250Hz 500Hz 000Hz 2000Hz 4000Hz STI Alcons% Scenario Scenario Scenario Scenario Scenario : Scenario 2: Scenario 3: no special acoustic treatment no special acoustic treatment plus JBL speaker system. Glass wool on the wall applied at the height of.5m from the floor level up to the ceiling level plus an NRC 0.9 acoustic ceiling panels on the whole ceiling plus JBL speaker system. Scenario 4: acoustic plaster Diathonite Premix on the walls from the floor level up to ceiling level + an NRC 0.9 acoustic ceiling panels on the ceiling + JBL speaker system. Applying acoustic plaster on the whole walls of the auditorium with acoustic ceiling further improve the sound field. In particular, it reduces reverberation time by more than 0.06 sec, increases STI by 0.2 and decreases Articulation Loss of Consonants AlCons by more than.5% Degree of intelligibility of dialogs in cinema auditoriums can be estimated based on two acoustic parameters: STI - Speech Transmission Index The STI is a 0 to index, indicating the degree to which a transmission channel (e.g. a speakers system and a room) degrades speech intelligibility. The closer the STI value approaches zero, the more information is lost. Alcons - Articulation Loss of Consonants Lower values of ALcons are associated with greater intelligibility. Zero ALcons indicates perfect clarity. It is recommended that a value of 5 percent should be reached. Anything more than 0 percent indicates bad intelligibility. STI Intelligibility Rating ALcons >0.75 Excellent 0-3% Good 4-7% Fair 8-5% Poor 6-33% < 0.30 Bad 34-00% 0

11 Case study Cinema "Ideal" - Lisbon - Portugal Cinema Ideal is the oldest cinema in the old city of Lisbon. In 204 it was completely restored and re opened to the public on August 28th. They used Diathonite Premix acoustic plaster in the cinema hall. In this way it was possible to maintain the curve shape surface of the cinema.

12 Case study A Motorway - Bologna, Italy In this particular application, Diathonite Premix has been used to reduce the noise level of a motorway section in the proximity of a town near Bologna. The application of Diathonite Premix directly to the concrete walls of the tunnel present in one of the two carriageways, it has reduced of 70% the reflection of sound waves, as well as decreasing of 3.5 db the reflected sound intensity. 2

13 Case study Luigi Bocconi University - Milan, Italy The prestigious University Luigi Bocconi chose Diathonite Premix as sound absorbing plaster for all its classrooms, auditorium, libraries, corridors and conference rooms of the new department built in 2006 in Milan. 3

14 Case study "Cucinelli theater" - Solomeo - Perugia, Italy Diathonite Premix has been applied inside the small but prestigious Cucinelli Theater of Solomeo, a town in the Umbria region, where the famous company "Brunello Cucinelli", known all over the world for the production of tailor-made, high-quality cashmere clothes, has its headquarters. The product, applied on every wall inside the theater, has allowed an effective correction of the reverberation. This has granted an excellent acoustic comfort in the whole theater, able to receive up to 200 people. 4

15 Case study "Cucina Torcicoda" Restaurant - Florence, Italy This is the renovation of a restaurant located in the famous central Santa Croce square in Florence. Diathonite Premix has been applied by plastering machine on every wall and ceiling of the restaurant. This product was the perfect choice to keep the characteristics of the structure (vaulted ceilings with complex geometries), adapting perfectly to the shape of the building. 5
