Responding to Questions About Concentrated Solar Reflection and Heat Distortion
Cases of siding distortion caused by concentrated sunlight reflected from windows have been getting media attention, leading to questions on the phenomenon. The Vinyl Siding Institute is committed to addressing these questions–be they from homeowners, builders, remodelers, architects, code officials or the media.
The questions answered here were pulled from reader comments posted to a number of media stories, and occasionally they are re-phrased to suit the format of this Q&A. Be sure to read VSI’s summary of the key points about the issue, and the technical review by the National Association of Home Builders first. These questions and answers are intended to supplement the information in those documents.
