High Performance Building We help you invent the future?'

High Performance Building • Trends in structural glass facades & impact on • High Performance Structural Glazing • New Engineering Solutions in structural design • High Performance Structural Glazing - Products • Crystal Clear Bonding • High Performance Insulation: Dow Corning ® Architectural Insulation Module We help you invent the future'

Facade design trend... Grey shades & coloured glass

Facade design trend... Curved glass- Single, Double Triple glazed units

Facade design trend... More glass, larger units, less frame

Challenges in highrise buildings... • Climatic changes increasingly impact highrise facade designs: – Designed for worst case wind loads – Hurricane safe – Temperature extremes

SUSTAINABILITY & ENERGY EFFICIENCY • Green Building, Low carbon foot print – LEEDS / BREEAM, DGNB, etc. • ENERGY EFFICIENCY, less CO2 • Longterm Durability – building lifecycle • Low Facade maintenance • Building Integrated PV • Etc.

Façade Trends vs. Technology Trend in high - rise buildings Curved glass High wind Protective Glazing Impact on Structural Design Higher Thermal dilatation High movement Capability Higher Loads Larger SG Joints Higher Design Strength Smaller joints

SG-Silicones – High Strength vs. High movement Higher Strength lower Movement Capability Higher Strength Higher surface stress Higher Strength Sealant 2-3 times higher surface stress Dow Corning 993 Structural Glazing Silicone
