Understanding Concentrated Solar Reflection and Its Potential Damaging Effects

Damage to property caused by concentrated solar radiation reflected off multi-pane Low-e windows is infrequent and occurs only under a unique set of conditions.

As exterior cladding is among the several documented materials repeatedly affected, the Vinyl Siding Institute (VSI) is committed to documenting and sharing available information related to this phenomenon.

If you are a member of the media researching this topic, we encourage you to start with our “Open Letter to Journalists.”

Builders, remodelers, and architects: We’ve included links to white papers that provide technical information.

And all are welcomed and encouraged to watch a less technical illustration of the phenomenon in this short video (below) or click links to the right to view media stories broadcast in local markets.
