Definition
Meaning and Definition
A material consisting of extremely fine filaments of glass, used for reinforcing plastics and resins, for insulation, and for making fabrics.
Also refers to the final composite product (e.g., fiberglass) made from these filaments and resin, known for its strength, light weight, and insulating properties.
Dialectal Variation
British vs American Usage
Differences
In British English, 'glass fibre' is the standard spelling for the raw material. The product is often called 'fibreglass'. In American English, 'glass fiber' is the spelling, and the product is 'fiberglass'. The one-word forms dominate in both dialects for common usage.
Connotations
Identical connotations of strength, lightness, and modern manufacturing.
Frequency
The two-word form is more frequent in technical and manufacturing contexts. The one-word form ('fibreglass'/'fiberglass') is far more common in everyday speech.

FAQ
Frequently Asked Questions
'Glass fibre' (or 'glass fiber') typically refers to the raw filaments of glass. 'Fiberglass'/'fibreglass' is the finished product—a composite material made by embedding those glass fibres in a plastic resin.
The fine fibres can irritate the skin, eyes, and lungs if inhaled. Proper safety equipment like gloves, goggles, and masks is essential when handling loose glass fibre insulation or during cutting/sanding of composites.
Recycling is challenging due to the combination of glass and resin. While the glass itself is recyclable, separating it from the polymer matrix is difficult and energy-intensive, making it less common than metal recycling.
Key advantages include high strength-to-weight ratio, corrosion resistance, electrical insulation properties, design flexibility, and relatively low cost compared to advanced fibres like carbon or aramid.
