The patented FCM curb mounted fixed skylight is sized to work with all types of site-built curbs, whether they're slightly out-of-square, pre-existing, or surrounded by unusually thick flashing and roofing material. Heavy-duty materials ensure the FCM skylight is built to withstand the installation process, as well as anything Mother Nature throws its way.
Green fact
Many times, model FCM skylights are used to replace old, inefficient plastic bubble skylights with energy-efficient insulated glass panes. (These are inexpensive and a handy DIY homeowner with proper tools can do the work in a few hours. Professional installation can be arranged).
