Cardinal IG Company of Eden Prairie, Minn. manufactured the reflective glass units.Four Seasons Solar Products, LLC, of Holbrook, N.Y., through its dealers and franchisees, sold and constructed sunrooms that used these glass units.
Cardinal IG and Four Seasons are aware of four fires that could be attributed to this scenario. There are no reported injuries. The damage ranged from minor damage to shingles and underlying sheathing to incidents that caused some structural damage to roofs and walls.
The repair program involves only the roof glass in sunrooms (including skylights installed as part of the sunroom) that reflect sunlight onto nearby cedar shingles or cedar shakes. It involves reflective Code 77 roof insulating glass units. It includes new sunrooms sold from 1996 through 2002, but possibly constructed later, and those sunrooms, regardless of when built, that had roof glass or skylights replaced with Code 77 glass from 1996 to 2005.
The glass was sold through franchisees and Four Seasons retail stores in the United States and Puerto Rico from January 1996 through October 2005.
Owners of Four Seasons Sunrooms described above should call the toll free number to determine if their units are affected and if so, to obtain a free repair. Cardinal IG and Four Seasons working together will repair the roof glass through installation of a capillary tube. The repair can be completed from the exterior of the sunroom except for certain types of skylights. There is no need to replace the glass.
