er, no...
Fibreglass is glass fibre, RCF is Refactory Ceramic Fibre...
;o)

True, but neither 'glass' nor 'ceramic' defines a single chemical substance.
RCF and fibreglass are both likely to be silicates, and their physical form is likely to be fibres.

RCF Composition % by Weight
RCF Alumina Silica Organic Binder
Group 1 65-88 0-15 6-27
Group 2 65-88 0-15 6-27
Group 3 96-99 - - 0-5
Group 4 82-96 0-15 0-15
Glass Fibre
Fibrous Glass (E-type, continuous filament)
Composition consisting principally of oxides, silicon, aluminium, calcium, boron and magnesium, fused in an amorphous vitreous state.
90.0% min
If I remember correctly the fibres have different sensitising effects.

Fibre Glass is a form of Silica (SiO2). Fiberglass, (also called fibreglass and glass fibre), is material made from extremely fine fibers of glass. It is used as a reinforcing agent for many polymer products; the resulting composite material, properly known as fiber-reinforced polymer (FRP) or glass-reinforced plastic (GRP), is called "fiberglass" in popular usage.
Refractory Ceramic Fibre (RCF)is a structure composed of Alumino Silicate. RCF is a category 2 carcinogen under EU classification. This is used for a number of specialist high temperature insulation applications within various industries.
