Meeting Title

Joe Lstiburek

The tragic fire in London, UK, raises issues with respect to claddings and continuous insulation in high performance buildings as well as retrofits. The first part of this session addresses the physics of the fire in London and why such an occurrence is unlikely in the United States and Canada.

Billions of dollars worth of hard coat stucco litigation have been filed within the last 12 months. What is driving the stucco failures? The patterns are eerily reminiscent of the failures of EIFS claddings in the 1990’s. The second part of this session addresses the changes in materials and construction practice leading to the failures.
