3 The origin of Tavego s name. Nomen, omen. Romans used to say that destiny is already written in names. The word Tavego comes from the contraction of two words: Tavola (board) and Ego. The wood (board), original and pure element, becomes constructive element and produces comfort for the individual (ego).

5 Sustainability Marlegno uses wood that comes only from PEFC certified forests, which guarantee a forest management that respects biodiversity requirements, development of the economic chain, regeneration capacity and maintenance of biological functions. Furthermore, wood is an extremely beneficial material because every cubic meter can store up to 2 tonnes of CO 2, subtracting them to the environment. Local raw materials Marlegno offers the possibility to build structures with wood coming from Italian forests as close as possible to its establishment. In this way it contributes to the development of the local business sector and drastically reduces energy costs associated with transportation.

7 Prefabrication The production of Tavego requires only mechanical connections with wooden or metal elements, carried out with simple equipment and with very low energy consumption (for example, the absence of glues means that no presses are used). The use of prefabricated elements also helps to increase quality controls into the establishment and to transform the construction site in a simple assembly site, reducing on-site operations and timing. Healthiness Tavego is an innovative construction system for indoor spaces: the absence of synthetic glues for production and assembly of panels means a better health condition of the interior spaces for buildings, due to the lack of harmful products such as formaldehyde.

20 Shrinkage and Swelling Technical Data Wooden panels for walls and floors are generally sensible to changes in Moisture Content (MC), which could cause swellings and shrinkages into the panel. Usually, a variation of 1% of the MC involves, for these types of elements, a dimensional variation around 0.25%. For these reasons, if in the indoor spaces it s not possible to guarantee a relative humidity lower than 70% for temperatures below 18 C, it s necessary to study, during the design phase, floor solutions accurately dimensioned. U.R. (%) MC (%) T ( C) Changes in Moisture Content of wood as a function of relative humidity U.R. (%) and temperature T ( C). [Source: Wood Handbook 2010]. Acoustics Tavego panels for floors, thanks to their mass and to the particular form and arrangement of joists, are an excellent solution for improving the acoustic comfort in indoor spaces. Sustainability Tavego panels for floors and walls have excellent characteristics of sustainability: Raw materials are PEFC certified; C24 boards come from Italian forests; The presence of mechanical connections guarantees an healthier indoor air; Panels are prefabricated and modular, easy to be removed and can be reused or recycled at 100%. Each cubic meter of a Tavego panel is able to store up to 830 kg of CO 2 *. * this value was calculated taking into account all the stages of production and carriage, from the trunk in forest to the finished product in Marlegno.

22 Certification System LEED Credits LEED, Leadership in Energy and Environmental Design, is a certification system that provides requirements for the design, construction and operation of environmentally sustainable buildings, both from an energy point of view and from the point of view of the consumption of all environmental resources involved in the realization process. regional priority sustainable sites water efficiency energy and atmosphere indoor environmental quality innovation materials and resources The LEED rating system is divided into 7 sections organized into prerequisites and credits. The prerequisites of each section are required so that the entire building can be certified; credits can be chosen depending on the characteristics of the project. The sum of the scores of credits determines the level of certification achieved. It s therefore important that the products that compose the building show with the utmost transparency their compliance with the LEED rating criteria and the contributions they can make to the satisfaction of the credit sough.

23 LEED Credits Marlegno, always careful to innovations in the field of sustainability, in order to allow designers to best develop their projects in this regard, has mapped its Tavego products thanks to the advice of QualityNet (Advisor specialized in certification).
