Even in the innovative and rapidly changing world of green building, some of the old ways and traditional materials are often the best. For thousands of years, natural clay and lime plasters have been used to create beautiful and long-lasting interior and exterior finishes. While these materials continue to be used extensively throughout the world, they have been largely replaced in North America by cement and acrylic stuccos.

Tale of Two Homes

San Francisco Bay Area Media

Today “green” construction comes in many different colors and flavors, depending on the style, need, material, criteria, architect, contractor, designer, environment, and much more. Two very different green homes in the San Francisco Bay Area were recently highlighted in detailed profiles, both finding St. Astier Lime Plaster to be the ideal solution for their exterior finishes.

Lime Plaster

limeplaster“What makes TransMineral USA’s lime-based plaster, mortar, and paint green? Most notably, their products contain no VOCs and no polymers, so there’s no off-gassing. The plaster Fine Homebuilding editor Chris Ermides reports on comes premixed (just add color) and applies in two coats. The result is a durable, smooth wall finish sealed with an olive-based sealant. The cost is $1 per sq. ft. for materials or $8 per sq. ft. for materials and application by a contractor-well worth it if you’re one of the millions of Americans with chemical sensitivities.”

“Today, there’s a big trend of using finishes from Tuscany, and all these faux finishes. Well, faux in French, means fake. Why would you want a fake finish when you can have a real finish,” asks Michel Couvreux.

Santa Clarita Transit Maintenance Facility Receives Award

January 2007

Santa Clarita Transit Maintenance Facility awarded LEED® Gold certification, sports St. Astier NHL exterior finish

Just awarded the Leadership in Energy and Environmental Design (LEED) Gold certification by the U.S. Green Building Council (USGBC), the new Santa Clarita Transit Maintenance Facility in Santa Clarita, CA, sports a St. Astier Natural Hydraulic Lime (NHL) plaster exterior and interior finish over a straw bale construction.

Completed in May 2006, and touted as a first for a government building—being constructed of straw bales—this LEED certification has attracted the attention of the press, including the Aug. 9, 2006 edition of the Wall Street Journal, and honorable recognition for the architectural firm of HOK Sustainable Design, making this their 12th project to earn a LEED recognition from the USGBC.

Among many of the building’s redeeming LEED qualities is that the lime plaster-straw bale combination allows for efficient, effective insulation, and a healthier environment due to a considerable reduction in carbon dioxide emissions compared to cement stucco.

“We were able to exceed California Energy Efficiency Standards by over 40 percent,” notes HOK Senior Project Manager, Charles Smith.
