1 PRODUCT INFORMATION TROLDTEKT PLUS Troldtekt Plus Added sound absorption ideal for retrofitting

2 Troldtekt Plus Added sound absorption ideal for retrofitting Troldtekt Plus helps you achieve the same excellent sound absorption as with a classic Troldtekt acoustic panel installed on top of mineral wool. However, you will save both fitting height and time at the building site. Simply put, Troldtekt Plus consists of Troldtekt acoustic panels covered with a layer of mineral wool on the back. Acoustic panel and mineral wool are thereby installed together, avoiding contact with loose mineral wool. Read more about Troldtekt Plus on the following pages and take inspiration from the two case studies. Enjoy!

3 > Added sound absorption For acoustic ceilings in general, the installation itself, or the construction, is an important factor in achieving the best possible sound absorption. The best effect, i.e. the widest possible effective area, is typically achieved by installing the acoustic ceiling mm from the fixed ceiling. To achieve optimum sound absorption it is customary to install the Troldtekt acoustic panels on top of a layer of mineral wool. The double-layer Troldtekt Plus panel incorporates the mineral wool and, when installed as a suspended ceiling, Troldtekt Plus provides optimum absorption through almost the entire spectrum see figure 4. However, even as a directly installed ceiling, Troldtekt Plus absorbs close to 100 per cent in the normal speech spectrum (>500 Hz) - and this with fitting heights of only 43 or 65 mm see figures 2 and 3. Not only do you reduce the fitting height but 43 mm Troldtekt Plus can also be installed on normal mm wooden battens, which can offer huge building project savings. Sound curves 1-4 show the absorption coefficient for different structures. You should aim for the highest possible α (absorption coefficient) values.

4 Simple installation With the double-layer Troldtekt Plus panel, the acoustic ceiling and mineral wool are fitted in one action! This saves time at the building site and means that workmen avoid contact with loose mineral wool. < Removal of the existing ceiling is not required! New wooden battens on the existing ceiling provides a sufficient base for Troldtekt Plus. << Some floor covering and a rolling scaffolding is all that is required and the renovation process can be completed in just a few days. Ideal for retrofitting The best results are achieved by incorporating acoustics in a construction project already in the project planning phase, as this provides multiple opportunities for elegant acoustics solutions using Troldtekt acoustic panels. However, if the damage is done and you have a room in which hard floors, large glass sections and smooth ceilings cause poor acoustics, the optimum solution is to replace the existing ceiling with a Troldtekt acoustic ceiling. Unfortunately, this requires an extensive renovation process, involving construction mess and lots of dust, which may seem to be insurmountable if the room is already in use. In this case, Troldtekt Plus is the ideal solution as the existing ceiling need not be taken down. Just screw new wooden battens onto As standard, Troldtekt Plus is 43 mm thick ( mm), so the panels can be installed on regular mm wooden battens. This can generate huge savings for a renovation project! If you need added sound absorption, Troldtekt Plus is also available in 65 mm thickness ( mm) for installation on mm wooden battens. the existing ceiling to ensure easy installation of Troldtekt Plus on the wooden battens. Some floor covering and a rolling scaffolding is all that is required and the renovation process can be over in just a few days. Removable ceilings Troldtekt Plus is the best solution for removable ceilings where workmen may subsequently require access to installations above the ceiling. In profile systems such as Troldtekt T35 for concealed or exposed installation, you just tilt up the acoustic panel to inspect and maintain installations above the ceiling. The back of the mineral wool is covered with non-woven material and glued to the back of the Troldtekt panels, so workmen completely avoid contact with mineral wool fibres. Acoustic clouds If a Troldtekt acoustic ceiling cannot be installed across the surface ceiling, floating acoustic clouds with Troldtekt Plus is an excellent solution. Just install Troldtekt Plus on the Troldtekt C60 profile system and terminate the clouds in Troldtekt aluminium profiles. This is an easy and elegant acoustics solution for limited areas.

6 One of the major construction challenges today is to make good acoustics, architecture and aesthetics come together in synergy. This is why Troldtekt acoustic panels are increasingly the preferred choice for project planners. Combined with today s strict requirements for sound absorption and easy-to-install, flexible solutions, Troldtekt Plus is being used ever more frequently. In our inspirational section at you can find a number of exciting case studies and pictures here are a few examples: ProDesign Rough and refined The internationally renowned eyewear manufacturer ProDesign has introduced functional large office landscapes into a former industrial building. Troldtekt clouds ensure that the acoustic environment as with all other interior decoration is easy to remove upon vacation of the premises. The Åbyhøj headquarters were a raw and naked industrial warehouse when ProDesign moved in. The office complex, owned by the property company Olav de Linde, had left it up to the individual tenants to decorate their rooms, including partitions, ceilings and lighting. However, the interior decoration had to be removed upon vacation of the premises, leaving the building s appearance unchanged. With Troldtekt Plus installed as clouds, the raw impression of the large office spaces has been retained but also refined into an inspiring work environment. wood wool is installed as floating clouds that help define the areas. The limited cloud surfaces still leaves a clear impression of the concrete behind them and removing the panels at a later stage is extremely easy. Creative Director Allan Rasmussen of ProDesign is also excited about the acoustic properties: These panels have an incredible effect in a building like this, with its hard concrete faces and glass walls. We have one showroom without clouds and the difference is striking. The acoustics simply change as you cross from one room to the other. It s very convincing. Inspiring industry ProDesign got help from architectural firm Merete Nielsen for the interior design. Architect MAA Merete Nielsen says: My starting point is always the existing rooms and for this project I found the rustic industrial environment very inspiring. ProDesign wanted large office landscapes and creating a functional office environment in the resonant concrete halls was no easy task. Acoustic clouds Merete Nielsen emphasises that a good acoustic environment is essential: That is why I chose Troldtekt not only does it support the existing mood but it seems almost refined compared to the existing grey cast concrete.

7 Client: KKG Architect: CEBRA KKG Graphically and culturally interwoven This interesting project involved connecting a high school with a technical college, merging two buildings into one where students from both could enjoy shared facilities. The project is the result of a limited competition won by Danish architects CEBRA, wellknown for their work on educational institutions and many other different projects. For them, it was a great architectural challenge which has resulted in an elegant and simple solution. The two schools were positioned at right-angles and originally functioned independently of each other. In order to link the two, the architects opted for a greater overlap between them. This crossover effect has provided the united building with a new architectural identity and horizontality. The common centre houses a canteen for both schools which also doubles as a venue for large gatherings in the shared auditorium and an upper level library. A particular feature is the extensive scale raked tier seating which encourages social interaction, study and leisure. One of the reasons why the new rooms work equally well for teaching, study or musical performances is the large scale use of Troldtekt acoustic panels in the design. CEBRA has frequently specified the panels in buildings where noise levels need to be controlled, such as in sports halls, kindergartens and shops. Here, the tiles are coloured in several shades of grey and run as parallel bands across the ceilings and complement the dark and light floors. This delicate interplay between the hard, reflective floor surfaces and sound absorbing, finely textured ceilings provides pleasing aesthetics and a great sense or orientation within the rooms. Project architect Mikkel Frost says: From concept to reality, it is almost something of a relief to find out if your assumptions about how the building will be used are correct - to hear speeches and enjoy the music or the simple satisfaction of observing students socialising, studying or just happily hanging out on the long staircase!
