• 40% of all energy is used to heat and cool buildings

• 39% of energy leakage passes through the wall

• EIFS provides continuous air barrier and a continuous layer of insulation

• EIFS reduces this leakage significantly

Requirements for fresh mortar:

• Good workability for manual and mechanical application

• Long open time

Requirements for hardened mortar:

• Good adhesion to polystyrene boards and other substrates (concrete, brick, old stucco)

• High flexibility and impact strength

• Good vapor permeability

• Hydrophobic properties (water repellency)

• Good weathering resistance

STRINGENT REQUIREMENTS FOR MORTAR AS THE CRITICAL COMPONENT OF EIFS


WACKER’S VINNAPAS® POLYMERS DELIVER ALL FOUR PERFORMANCE FEATURES

• Improved adhesion to all substrates (polystyrene, polyiso-C, concrete, bricks, old stucco etc.)

• Increased flexibility and improved impact resistance

• Excellent hydrophobicity• Durability and long-term

performance

WACKER’s VINNAPAS® products give EIFS stability, flexibility and durability

Functions of VINNAPAS® Polymersin EIFS mortars:


LABORATORY TESTING IS MANDATORY FOR A SUCCESSFUL EIFS SYSTEM


VINNAPAS® MAKES THE DIFFERENCE

Savings during the last 50 years reached with EIFS in Germany:

~ 7,950,000,000 sq.ft. installed EIFS

~ 63,660,000,000 gallons Savings in heating oil ~ 670,000,000 tons Reduction in CO2 ~ $174,000,000,000 Lower heating costs (oil price 2007)

THE GERMAN EXPERIENCE

Source: Market study “Quo vadis WDVS 2007-2012“

• EIFS has been a well established and approved building method for several decades.

• EIFS is ecological since it reduces residential energy consumption and CO2 emissions significantly.

• EIFS is economical since it reduces heating costs significantly with reasonable expenditures.


EIFS POTENTIAL CONTRIBUTION TO LEED® PROJECTS

• U.S. Green Building Council has developed Leadership in Energy and Environmental Design (LEED®) Green Building Rating System.

• Points for materials, construction methods and systems that minimize a building’s impact on the environment.

• EIFS can contribute significantly to attainment of:

• LEED® Energy and Atmosphere Credit 1 – via air barrier and broad range of R-Values

• LEED® Material and Resource Credits 1 and 2 – via installation of EIFS to existing structure and building reuse

WACKER‘S TARGETS FOR THE SOUTHERN U.S.

Our Targets

• We want to promote EIFS • We want to promote a “System Mindset” for EIFS

• We want to promote quality awareness in the field of EIFS and dry-mix mortars

We are looking forward to discussions …

• … with architects, construction companies & specifiers on EIFS and trends in exterior wall insulation.

• … with authorities on system quality and norms • … with individuals who want to enter the EIFS field
