Clarifying cool roofs

I am writing regarding "The un-cool consequences of cool roofing," July issue, page 36, by Samir Ibrahim, director of design services for Carlisle Construction Materials, Carlisle, Pa.

Although, as the author points out, recognition of the energy and environmental benefits of cool roofing goes back only 15 years or so, many highly reflective membranes have been in use for much longer than that.

My company has produced nothing but light-colored, highly reflective membranes for more than 50 years. Being a Boston-based company, many of our earliest reference projects, which continue to perform problem-free, are located in New England and exhibit none of the condensation or loss of adhesion issues attributed to cool roofs in the article.
