Valerie Block will examine the safety concerns around glass in railing systems and the new building code requirements that address the use of these systems. The results of impact testing will be presented, and the need to verify the compatibility of sealants and grouts will be discussed. The course will cover issues such as different glass types used in railing systems; laminated glass interlayers and the role they play in glass retention after breakage; building codes and standards that are directed toward glass railings in buildings; and the difference in post breakage performance of glass types in minimally supported glass systems, among others.
Block works with architects and specifiers, structural engineers, façade consultants and glass fabricators on the specification, design and use of laminated glass in buildings. She has chaired the Glazing Industry Code Committee and is a frequent speaker and author of articles about the use of glass in buildings. Block brings more than 30 years of experience in the glass and glazing industry.
