STRINGENT REQUIREMENTS FOR MORTAR AS THE CRITICAL COMPONENT OF EIFS 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 Messrs. Hepburn & Tessier, November 2009, Slide 17
WACKER S VINNAPAS POLYMERS DELIVER ALL FOUR PERFORMANCE FEATURES Functions of VINNAPAS Polymers in EIFS mortars: 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 Messrs.

THE GERMAN EXPERIENCE 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 CO 2 ~ $174,000,000,000 Lower heating costs (oil price 2007) EIFS has been a well established and approved building method for several decades. EIFS is ecological since it reduces residential energy consumption and CO 2 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 Messrs.
