1 name / slide Nr 1 The Company

2 name / slide Nr 2 1835 Cement and lime factory Weizen 1955Start of organic render production 1965First EWIS developped 1992Sto AG is floated on the stock exchange 1996StoCretec becomes separate subsidiary 2000Takeover of Shanghai Dinova Ltd., China 2001Acquisition of ispo GmbH, Kriftel today4000 employees 18 international subsidiaries 1 mission From lime factory to Sto brand Building with Concience

3 name / slide Nr 3 Sto AGs Mission statement The basis of the companys guiding principles Maintaining the value of old and new buildings is a permanent problem for building owners, investors and users. In its quest to solve this problem, Sto researches, develops, produces and markets product systems and services, with the aim of maintaining and improving the substance and functions of walls, ceilings and floors, and providing long-term protection from damage. This functional area of work is accompanied by services relating to the aesthetic design of buildings in terms of colour and structure. Sto wants to act as a pacemaker and play a leading role in helping to ensure that the world in which we live is designed in line with environmental requirements and our needs as human beings. We therefore collaborate with like-minded customers and partners. Our declared aim is to comply with our companys guiding principles in our dealings with all those involved in the building sector. Stos mission statement can be summed up in three words: Building with conscience.

4 name / slide Nr 4 External Wall Insulation Systems

5 name / slide Nr 5 Introduction Why thermal insulation? Reserves of fuel materials for heating (e.g. fuel oil, gas, coal) are not unlimited and not substitutionable Reduction of toxic emissions e.g. CO 2 (hothouse effect) Sto façade insulation systems account for around 35 billion litres of heating oil thus avoiding the emission of over than 110 million tons of CO 2

6 name / slide Nr 6 External Wall Insulation Systems Advantages of external wall insulation systems Energy saving (up to 60%) Environment: less toxic emissions, less fuel materials. Elimination of thermal bridges. (Ceilings, geometrical thermal bridges, etc.) There, where internal insulation now is existing: No condensation anymore in the wall construction. Reduction of temperature tensions. Increasing of the wall surface temperature inside. No risk anymore for mould spots. A better using of the heat accumulation capacity. The facade is protected against heavy raining. A new optical attractive facade.

7 name / slide Nr 7 StoTherm Classic Benefits of the Sto External Wall Insulation System

8 name / slide Nr 8 Substrate: Structural wall, brick, block, timber frame etc Insulation board Reinforcing coat + mesh Sto decorative finish render Acrylic/Silicone StoTherm Classic = Organic + + System Concept Fixing

9 name / slide Nr 9 thickness density thermal conductivity Insulation product Expanded Polystyrene, EPS insulation quality high crack resistance high resistance to mechanical stress low coefficient of thermal elongation permeability to CO 2 and to water vapor elasticity hydrothermal behavior long term durability EPS

10 name / slide Nr 10 Insulation Board Types used for Insulated Render Systems EPS - largely preferred choice (min. wool, PUR, foamglas, corc)

11 name / slide Nr 11 Calculation of the U-value: Wall structures are usually composed of several layers (internal plaster, brickwork, external plaster and/or thermal insulation, wall finish etc.). Each layer of material has a thickness d [m] and a own thermal conductivity coefficient [W/m.K]. The thermal resistance (d/ of each layer of material is added to the internal and external surface resistances (1/. The sum is the total thermal resistance (R) for the total (wall) construction. The inverted value of this figure is known as the total thermal transmittance: U- value. + + U-value: the smaller, the better + + INSULATION Total Thermal Transmittance U [W/m².K]

12 name / slide Nr 12 Wall constructions (examples): Old dwelling houses: U = 1,00 - 1,50 Not so very old dwelling houses: U = 0,70 -1,00 New dwelling houses: U = 0,35 - 0,40 Low energy dwelling houses: U < 0,35 INSULATION Total Thermal Transmittance U [W/m².K]

13 name / slide Nr 13 U = 0,37 W/m².K 0,30 m 0,10 m EPS As separate materials: 0,40 m Concrete U = 3,20 W/m².K U = 0,36 W/m².K Both materials in one system: INSULATION Total Thermal Transmittance U [W/m².K]
