Fiber bloom is where the constant exposure to UV rays of the sun erodes the matrix of the material and exposes the glass fibers. With preventative maintenance, by coating the surface, it can be stopped. However, without the maintenance, it can proceed to the point where replacement is the only viable solution.

Such is the case with the skylights at LifestyleRx a wellness center in Livermore, California.
