3 What benefits, The Benefits Excellent reverberation control. Noise reduction = stress reduction (at home and at work). Good acoustics = improved work efficiencyand performance. Enhanced listening experience. Excellent design fjexibility - can be applied on curved and vaulted ceilings. Jointless acoustic finish. Non polarized material ensures low maintenance and easy cleaning. Can be applied equally well to hard substrates or suspended ceilings. Non hazardous. Easyto maintain and repair. Uses 80%recyclable material. Incombustible. Vapour permeable. Excellentfungal resistance. Ambient Acoustic plasters are members of Terraco's ultra-environmentally friendly EcoLife range. 50 standard colours, full colour spectrum on request. Acoustics and aesthetics, enjoy both with Terraco Ambient System. Terraco Ambient Main Components Terraco Ambient Acoustic Systems are comprised of 3 main acoustic components which are used in various combinations to achieve the desired acoustic properties. 1. Ambient Basecoat Terraco's high quality acoustic performance plaster. Typically applied in layers of 8-18 mm to create the main absorbent layer. 2. Ambient Finishcoat Terraco's decorative acoustic finishing plaster. Applied as the final coat in layers of 2-3 mm. Ambient Finishcoat is available in a wide range of colours and can be finished smooth or with a spray texture. 3. Ambient Acoustic Board Acoustic mineral fibreboards. Usually used in thicknesses of mm. System Options The Ambient acoustic products, in conjunction with other components such as Ambient Primer and Ambient Adhesive are combined to produce several versatile system options. Some of the most popular ceiling systems are outlined below with comparisons of relevant coefficients of absorption mm Ambient Basecoat + 2 mm Ambient Finishcoat (A) (B) (C) The full Terraco Ambient System includes 18 mm of Basecoat and 2mm of Ambient Finishcoat.This system is both easy to apply and cost effective. For less demanding applications 8 mm of Ambient Basecoat is combined with 2 mm of Ambient Finishcoat. For specific applications a 30 mm Ambient Acoustic Board is combined with 3 mm of Ambient Finishcoat.The backing board gives the systema greater dampening effect on certain frequencies c::.!!:! 0 7 v IE 0.6 Q) 'il 0 3 ~ 0.2 ~ 0.1 o Frequency 30 mm Ambient Acoustic Board + 3 mm Ambient Finishcoat (Hz)

4 Environmentally Friendly Terraco has constantly pushed the boundaries in environmentally friendly finishing materials - spearheading new technology and production techniques. The company takes pride in its flawless ecological track record and always aims to be the first to make new advances in ecological products available to the end user. EcoLife marking denotes that a product is a part of Terraco's EcoLife range. This range of products has been formulated to comply with the most stringent national regulations in the world pertaining to interior decoration products. The products contain specially developed polymers and additives containing zero volatile organic compounds (VOCs)which ensure their inertness and ecologically friendly nature. Research & Development The Terraco Group is committed to an extensive Research & Development Program. The Technical Centre, based in Ireland, heads up the group's in-house product development program and is responsible for making sure that Terraco products remain at the forefront of their field with regard to innovation, quality and environmental standards. Terraco cooperates with several technology partners and suppliers, conducting joint research projects in common interest areas. KBS Dubbing Room Stanley House, London Chapel Room, Seoul Quality Assurance The Technical Centre implements strictly monitored quality control procedures at all production facilities ensuring homogenous, high quality products.

5 Acoustics, Acoustics - the issues Positively harnessed acoustics are a part of every day life and are commonly used to enhance and amplify for example musical performances. Unwanted sound or noise can however cause great discomfort and pose a serious health hazard that greatly reduces efficiency in the workplace and quality of life in general. Reverberation - the basics In enclosed spaces sound waves reflect, blend together, build up and create reverberation. Sabine's formula T = Reverberation time The method of quantifying reverberation time was first developed in 1900 by Wallace Clement Sabine, an American A = Average absorption ~'/ x V V = Volume in m3 l T= A x 5 coefficient of the room,p S = Total surface area of physicist, following an instruction the room in m' to remedy acoustical difficulties in the lecture room at the Fogg Art Museum. Reverberation time is the time required for the amplitude of sound to drop by 60 db (after the source has ceased transmitting) Popular design themes, such as minimal ism, produce architecturally pleasing environments - the emphasis being on clean, unobstructed spaces and areas. Such designs, however, generally incorporate hard, flat surfaces - which have a negative effect on reverberation and exacerbate unpleasant noise. Properly controlled acoustics are becoming increasingly important for architects, designers and builders across the globe as they strive to meet design criteria while ensuring the minimization of negative acoustic effects. Experience Terraco understands the science of acoustics - but more importantly prides itself on its knowledge of how to control acoustical properties in practice. The company has extensive experience in real acoustic engineering in public and private applications. Terraco's acoustic products, such as Terraco Ambient, have been designed and formulated to provide versatile solutions to acoustic problems in the real world. Ecological products for the present and future The modern Terraco materials, developed over many years, for a variety of diverse applications have stood the test of time and can be relied upon to cope with the demands of the 21stcentury.
