KEEPING GLAZED WALLS HEALTHY

摘要

Like many Other building components, curtain walls do not last forever. "These installations have a finite service life," says Thomas Schwartz, president of the Waltham, Mass., engineering firm of Simpson, Gumpertz & Heger (SGH), which has a major curtain wall consulting practice. Schwartz says many building owners are shocked to learn that a major component of the exterior wall, insulated and laminated glass units, may require replacement well before the remainder of the curtain wall. He finds that the durability of major exterior wall components is often insufficiently evaluated as part of the due diligence in buying a property.
