Fibreglass consists of thin fibres made of glass. To manufacture glass fibres,
molten glass is stretched into thin strands. As well as being used in fibreglass
cables for the quick transmission of data, fibreglass is also optimal for use in
The fibres are woven into materials, so to speak. These are available in
various formats that are suitable for different demands.
Because of their material properties, glass fibres are among the most important
construction materials in the world – they are
- dimensionally stable:
Even in extremely high or low temperatures, glass fibres do not contract or stretch.
- ageing and weather-resistant:
Glass fibres do not absorb moisture. Water does not have any effect on them –
neither physically nor chemically.
- solid, but highly elastic:
Glass fibres have a high strength-to-weight ratio. This is why they are so suited
for use in products that demand high strength with minimal weight.
- chemically resistant:
Only a few chemicals, such as hydrofluoric acid, hot phosphoric acid or highly alkaline
substances can attack glass fibres. The inorganic textile fibres do not mould, rot or disintegrate.
as an inorganic material, glass fibres do not burn. Neither do they encourage combustion.
Even at temperatures of over 500°C they continue to possess around 25% of their original strength.
- low level of heat-conduction:
Fibreglass cloth has a low coefficient of thermal expansion and a low degree of heat-conduction.
