2 Lumir Oy We are company specialized in biofibre based acoustic solutions Lumir acoustic solutions are an easy way to decrease reverberation caused by sounds reflected from hard surfaces, such as windows, hard walls and floors. Lumir acoustic solutions do not only please the ear, but also the eye. Acoustic surfaces can be prepared seamlessly with any desired colour and several different surface structures Sound Reflected sound Surface with bad sound absortion In space with bad acoustics and long reverberation time speech becomes noisy and difficult to comprehend Lumir acoustic coating In space with good acoustics speech is clear and easy to comprehend

3 Lumir acoustic coating is produced from biobased raw materials glass wool free sound absorption main component biofibres also binders are plant-based patented 3D sound absorbing structure

4 What REALLY matters? Hype about biobased materials can easily lead to disillusions about the advantages of products Reseacher Biobased Performance Appearance Price Easy Installation Architects Appearance Performance Price Biobased Contractors Price Easy Installation Acoustics consultants Appearance Performance Biobased products have to be cheaper and outperform conventional solutions or have completely new properties!

5 Lumir Board structure Lumir Board combines seamlessly advantageous properties of hard gypsum board and porous biofibre coating Lumir acoustic coating Good sound absorption on high frequencies Creates seamless surface Knauf Cleneo Lumir perforated gypsum board Contributes to stiffness of structure Good sound absorption on low frequencies Lumir board is tough and durable compared to, for example, glass wool panels

6 Installation and maintenance Lumir Board acoustic system is easy and quick to install as seams dont need to be spackled or taped Installation easier then painting a gypsum ceiling or wall Lumir coating can also be sprayed directly on hard surfaces Lumir acoustic surfaces can be cleaned by sanding or by wiping with dry or moist cloth Dust-proof Lumirmaintanance hatches can be installed

8 Acoustic properties Lumir acoustic solutions can be used enhance acoustics and decrease reverbation in various kinds of rooms

9 Lumir acoustic solutions are safe Broken acoustic panels are one of the main reasons for poor indoor air quality *. Lumir acoustic coatings are produced from biofibres which do not irritate skin or airways. Binding agents of Lumir coating are plant-based and do not form formaldehyde, VOCs or other harmful compounds Lumir Board is fireproof (B-s1-d0 classification), does not emit VOCs (M1-classification), and has been tested VTT Technical Research Centre of Finland ja Finnish Institute of Occupational Health * Finnish Institute of Occupational Health

10 Surface properties Lumir coating can be coloured according to RAL and NCS colour charts. Raw materials used for coating are coloured, which makes colour even and ensures that possible damage is more difficult to see. Structures under the coating do not become visible over time due to chemically inert gypsum. Coating can be done with smooth or coarse structure Surface can be treated to become water and dirt repelling

11 Lumir is researching new ways to improve acoustics New materials are constantly studied for acoustic solutions Focus on biobased and recycled raw materials We are working in collaboration with Aalto University and acoustic consultant companies Sound absorption tests are done in specially designed reverbation chamber build at Lumir

12 Lumir Hygiene antibacterial acoustic coating Lumir Hygiene-coating kills harmful bacteria when in contact with them After 1 hour no living bacteria could be observed Antibacterial properties were tested with Escherichia coli ja Staphylococcus aureus (MRSA) bacteria at Aalto University Additives used in Lumir Hygiene are not harmful to humans Lumir Hygiene coating can be done with all the color and surface structures as Lumir Board without affecting the acoustic properties

13 Lumir Audio and Coolia-Lumir Lumir acoustic coatings can be used to embed audio systems and cooling elements seamlessly into the walls or ceilings Sound and cool air can easily penetrate porous Lumir Comfort-coating With Coolia-Lumir turn your ceiling into silent and sound absorbing cooling (or heating) system - Cooling at 14 C water temperature about 50 W/m 2

14 Case 1: Office room You can influence satisfaction and work efficiency with acoustics Office room area about 18 m 2 Recommended reverberation time is 0.7 s Half of the ceiling of the room was replaced with Lumir Board system Reverberation time in the office decreased from 1 s to 0.6 s in frequencies of speech Jälkikaiunta-aika enne ja jälkeen absorptiomateriaalikäsittelyn* *measurement done by Akukon Oy
