Metal Roof Coatings: 50 Years of Development

Provider: Englert Inc.
Program Number: E104
Lu Hours: 1.00
HSW: Yes

Description: According to the presenter, this program is the most comprehensive review of metal roof coatings ever presented. It focuses on several different types of metal roof coatings, including their composition, features, benefits and weaknesses--all supported by references to performance testing. It also investigates the relationship between cool metal roof coatings and the LEED program, specifically Credit 7.2 for roofs that reduce the urban heat island effect.

The presentation concentrates on the three components of coatings--resins, pigments and solvents--and reviews the coil coating process. It examines the three primary resins used for coil coating exterior metals--polyesters, silicone-modified polyesters and polyvinylidene fluoride--and their strengths and weaknesses, and discusses the testing that paints undergo to determine performance characteristics. The session also reviews the three concerns facing metal coatings including fading, chalking and loss of gloss retention. And it reviews in detail the differences between LEED and Energy Star standards for evaluating cool roof coatings, including solar refectance, thermal emittance and Solar Reflectance Index (SRI) used to measure the effectiveness of roofing materials. The unit rounds out with a look at emerging coating technlogies.
