2 Africa, Middle East The company STEICO The company STEICO AG - Feldkirchen founded 1959 Headquarters Sales western Europe Technical dept. and R&D 42 employees STEICO S.A. - Czarnków STEICO S.A. CzarnaWoda STEICO Ltd - Dartford founded 1964 founded 1962 founded 2006 Production plant Production plant Sales UK and Ireland Sales eastern Europa Softboards 3 employees Softboards Hardboards Hampfibre insulation 186 employees Hardboards I-Joists 625 employees The company STEICO Ltd. North America STEICO S.A. STEICO AG Asia

3 The company Quality control Certified quality Production certified ISO 9001: 2000

4 Quality control Quality control strength properties Tests for the material the building parts universal testing machine for compression strength bending strength tensile strength shear strength testing facilities for loads of 10 kn 20 kn 100 kn Quality control Quality control material testing Determination of the fire class Measurement of the thermal conductivity Measurement of the wind-proofness

5 Product knowledge Product knowledge All in one wood as an insulating and energy saving material Construction Sheating Cavity Insulation Sound protection

6 Product Product range Products STEICO S.A. S.A. Construction Insulation for for roof roof and and ceilings ceilings Wood Wood fibre fibre Hemp Hemp for for walls walls loose loose fill fill flexible flexible pressure-proof flexible flexible pressure-proof Product knowledge Insulation from renewable resources Wood product without harmful additives Resistant against aging, as durable and natural as its raw material

7 The production Production of wood fibre insulation boards Wet processing system Dämmstoffe aus Holz Ökologisch. Ökonomisch. Gut. The production Dewatering machine (forming line) Drying and bonding of the boards on several layers End of the dryer and cutting process Final treatment of the boards

8 The production Production of wood fibre insulation boards Dry processing system Product Wood fibre - loose fill Note of authorization Thermal conductivity Density Packaging Z ,040 W/(m*K) kg/m³ PE-bags of 15 kg

9 Product Wood fibre - flexible Size Thickness Thermal conductivity Density 1220 x 575 mm (625 / 670 mm) mm 0,039 W/(m*K) 50 kg/m³ Produktkenntnis Wood fibre pressure-proof Double security Triple functionality: windtight waterresistant sheating insulation

10 Installation STEICOuniversal / STEICOspecial Product Size Thickness Thermal conductivity Density 1300 x 590 mm 2600 x 1180 mm (20) / mm 0,049 W/(m*K) 250 kg/m³

11 Objects Energy saving High energy saving in winter resting air that is located between pores and interspaces effects thermal insulation carefully realized air-thightness and windproofness low thermal conductivity λ D (Lamda declare)

12 Summer heat protection Excellent heat protection in summer time low thermal conductivity λ high specific thermal capacity c p high density ρ low thermal diffusivity a perfect windproofness Summer heat protection Reduction of the temperature across a building component Amplitude attenuation Phase shift Phase shift up to 15 hours possible!

13 Summer heat protection Construction comparison Mineral fibre 1 roof tiles 2 lathing 3 counter batten 4 sarking membrane 5 mineral fibre 200 mm 6 vapour barrier 7 mineral fibre 40 mm 8 gypsum board 12,5 mm Thermal transmittance: Amplitude attenuation /1/TAV): 6 U = 0,18 [W/(m²*K)] Phase shift ϕ : 6.8 hours Summer heat protection Construction comparison 1 roof tiles 2 lathing 3 counter batten 4 sarking membrane 5 STEICO flex 200 mm 6 vapour barrier 7 STEICO flex 40 mm 8 gypsum board 12,5 mm Thermal transmittance: Amplitude attenuation /1/TAV): 12 U = 0,18 [W/(m²*K)] Phase shift ϕ : 11 hours

14 Summer heat protection Temperature range at the roof with different insulating material External temperature Internal temperature with mineral wool Internal temperature with wood fibre insulation Diffusion coefficient Diffusion coefficient and sorption Diffusion = mass flow from places of higher to places of smaller water vapour concentration Low diffusion resistance factor µ stands for a high diffusible building material µ = 5

15 Diffusion coefficient Diffusion coefficient and sorption moisture content mass [%]] moisture content mass [%]] wood wood fibre fibre mineral mineral wool wool Sorption = adjustment of the moisture content of the material to the humidity A building material with sorption behaviour regulates the indoor climate (climate buffer) relative humidity [%] relative humidity [%] Diffusion coefficient Moisture absorption 1 m³ wood fibre insulation Up to a moisture content of 20 % Moisture absorption of mineral wool: 2% Density: 25 kg/m³

16 Fire protection Building material and construction Tests according to EN standards Fire protection Building material Fire class DIN 4102: Euroclass: B2 E

17 Fire protection Construction Fire resistance class According DIN 4102 up to F90 B (90 minutes fire resistance) According to EN REI 30 up to REI 90 Wood fibre products have a favourable fire behaviour (carbonization) Sound protection Sound protection Roof construction Foam board insulation R w,r 37 bis 49 db Wood fibre insulation R w,r 43 bis 53 db

18 Product Product I-Joist Building System for walls Only forces along the I-Joist-axis allowed Just 6 mm NFB-web. Reduction of thermal bridging Available in a pre-insulatet option

19 Product Reduction of thermal bridging Installation of services Product Lightweight product High bearing capacity
