Although we generally refer to the towers as being constructed of fiberglass, we should actually refer to them as being FRP (Fiberglass Reinforced Plastic)

FRP should not be confused with the translucent fiberglass roofing panels, and in particular with the cheaper grades which have given poor results even only in a few years. Without an adequate protective layer, the sun's ultra violet rays draw the fibers upward so that 'hairs' appear to be growing on the panels as with fiberglass hulls, the "Advance" tower casings have a protective Neopently Glycol gel coat, which apart from containing the pigment colour, entirely resists the sun's rays. As a result, "Advance" towers do not need painting. However, if a client wishes to have a colour scheme changed, painting is possible.

Compared with timber towers which will ultimately rot, or steel towers which will rust despite increased maintenance, the fiberglass tower has a tremendous financial advantage for the wise investor. Unfortunately, many buyers appear to be only concerned to maintenance, running costs or rate of deterioration.
