Asbestos vs. Fibreglass — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Updated on April 24, 2024
Asbestos is a natural silicate mineral known for its heat resistance and durability, while fibreglass is a synthetic fiber, prized for its lightweight and insulation properties.

Key Differences
Asbestos is a naturally occurring mineral that has been used extensively in construction for its fire resistance and insulating abilities. In contrast, fibreglass is a man-made material composed of fine glass fibers, used similarly for its insulation and non-flammable properties.
Asbestos fibers are strong and resistant to chemicals and heat, making them ideal for use in high-temperature environments. On the other hand, fibreglass also exhibits resistance to heat but tends to be less durable in chemical-heavy environments compared to asbestos.
One of the significant risks associated with asbestos is its health hazard when inhaled, as its tiny fibers can cause severe respiratory issues, including cancer. Whereas fibreglass is generally considered safer, though it can still irritate the skin, eyes, and respiratory tract upon contact.
In terms of environmental impact, asbestos disposal is heavily regulated due to its hazardous nature, requiring special handling and disposal techniques to avoid contamination. Conversely, fibreglass involves less rigorous disposal methods, though it is not biodegradable and still poses environmental challenges.
Asbestos use has declined significantly due to health risks, leading to bans in many countries. In contrast, fibreglass remains widely used in various applications, including insulation, automotive parts, and recreational items, benefiting from its relative safety and versatility.

Handling fibreglass requires protective gear to prevent skin and lung irritation.
Asbestos
Banned or restricted in many countries.
The use of asbestos is now banned in over 50 countries worldwide.
Fibreglass
Used in a variety of products.
Fibreglass is used in boat manufacturing due to its lightweight and strength.
Asbestos
Asbestos (pronounced: or ) is a naturally occurring fibrous silicate mineral. There are six types, all of which are composed of long and thin fibrous crystals, each fibre being composed of many microscopic "fibrils" that can be released into the atmosphere by abrasion and other processes.
Fibreglass
Silica based glass extruded into fibers that possess a length at least 1000 times greater than their width.
Asbestos
Any of six incombustible chemical-resistant silicate minerals, including one serpentine (chrysotile) and five amphiboles (amosite, crocidolite, and fibrous forms of actinolite, anthophyllite, and tremolite), that separate easily into long, thin, flexible fibers and that have been widely used commercially in products such as fireproofing, electrical insulation, building materials, brake linings, and chemical filters. Mining and use of asbestos has been restricted because inhalation of asbestos fibers can cause asbestosis and cancer.
Fibreglass
Ellipsis of fibreglass wool
Asbestos
Fabric or material containing any of these mineral forms.
Fibreglass
