3 Content of this presentation: l Short introduction of Eltomation; l Summary of Wood Cement Products; l Short movie showing production process; l Applications of Wood Wool Cement Boards; l Massive WWC building elements; l Summary of product properties.

4 Eltomation BV - Holland l l Engineering company based in The Netherlands Supplier of turn-key wood-cement board production plants l 52 years in business l Leader in this field of technology l Over 150 plants and systems installed in over 35 countries

5 Various Wood Cement Products: l Wood Wool Cement Boards and massive WWC elements; l Wood Strand Cement Board - EltoBoard l Cement Bonded Particle Board - CBPB l Wood Waste / Wood Residue Board

6 Wood Wool Cement Board (WWCB)

7 Properties of Wood Wool Cement Boards: Good thermal insulation Excellent heat buffering capacity Wet and dry rot resistance Fire resistance (B1 classified) Termite/Vermin resistance Good sound absorption Excellent base for stucco and plaster

8 Properties of WWC (part 2) l l l l l l l Light weight to handle; Easy to process in construction; Relative low energy consumption to produce; No fossil fuel or binders used; Limited impact on local natural resources. No waste product at end of life cycle; Nice and attractive natural look visual appearance.

16 Applications of Wood Wool Cement Boards

17 Applications of Wood Wool Cement Board in: Basements and Floor Units Outside Walls - Permanent Shuttering - Insulation of Concrete - Large size Wall Elements (Sweden) Roofing Renovation Ceilings, Acoustic Absorption Sound Barriers

18 WWCB Wood Wool Cement Board Applications Basements and Floor Units

19 WWCB for permanent shuttering of the floor above the basement

20 WWCB seen from below Providing: - Thermal insulation - fire protection - sound absorption

21 WWCB Wood Wool Cement Board Applications Outside walls Permanent Shuttering

22 High thermal insulation for temperature of 35 ºC

24 Permanent Shuttering in the Ukraine

52 Large size Wall Elements

53 Properties of large WWC element: l Dimensions: 600 x 260 x 40/50 cm l U-value: 0,19 W/m 2 C; l Thermal storage capacity: 250 KJ/m 2 C l Density of approx. 300 kg/m 3 l Allows a speedy construction l Good base for stucco and plaster l Allows last minute adjustments in construction (flexibility). l Present costprice arround 40,- p/m 2

54 Molds ready for production Production of Massive WWC elements in Sweden (distribution of woodcement mixture)

56 and erection of the walls starts immediately WWC elements arrive at the building location..

57 Construction adjustments can be made at the spot..

58 Fixing the elements together, reinforement bars between the joints

59 `` Construction results after one day.. Project in progress

61 Summary Wood Cement Boards v Proven and reliable building material (applied in >25 European countries in the last 50 years) v Unique properties (high (high thermal insulation, resistant to fire, moulds/fungus and insects,, sound absorbtion, light weight etc). v Ecological (green) image (low low impact on natural resources, energy consumption, attractive visual appearance and possibility to recycle
