What are the pros and cons of fiberglass?
Fibreglass last a long time, it can be coloured, shiny or dull. It is low maintenance, anti-magnetic, fire resistant, good electrical insulator and weatherproof. The disadvantages is that it needs to be re-gel coated about every five years and can result in airborne fibres which may be an issue to asthma sufferers.
