We all know about that itchy ‘stuff’ in the loft that you’re always warned not to touch Insulation in our homes is one of the most important aspects of our home; it also has a massive effect on our energy bills! We all know that heat naturally flows from a warm space to a cool space and both our home and our wallets suffer from this because you’ll be itching for hours.


Remember that itchy stuff that was mentioned earlier? That stuff is called Fibreglass Insulation- a man-made mineral fibre constructed to form a variety of materials, such as sand and recycled glass. Fibreglass Insulation can cause various different health problems, such as:


Skin irritation - Fibreglass insulation is also called glass wool because well, that’s literally what it is. The sand particles and the glass are heated and spun until they form thin fibres of glass particles that are bonded together.


The tiny fibres of glass from the insulation can irritate your skin and eyes. With too much contact comes the ‘irritant’ called contact dermatitis (inflammation of the skin). Breathing in the fibres can also hinder breathing.

Fibreglass, in a sense, phased out Asbestos. Asbestos, unlike fibreglass, is a natural silicate material found in rocks. With it being known to go back to the Ancient Greek times, it has always been admired for its withstand against high temperatures- it's not just resistant to high temperatures, it doesn’t evaporate in the air or dissolve in water or react with most chemicals. These properties made this material very popular and the main material insulation in the late 19th and the majority of the 20th century.

So right now Asbestos sounds like the better option? Why was it phased out?​

The health risks that came with Asbestos were very hazardous. Once Asbestos is inhaled the fibre travel through down to the lungs where they stay for long periods of time, the fibres then start to irritate the lungs and any other parts of the body they travel to- this disrupts cell division by interfering with chromosome distribution and changing genetic material. This increases the chances of becoming ill and having illnesses such as Asbestosis, mesothelioma, etc.


Asbestos is a natural material whilst Fibreglass is man-made- these two materials are often compared because they’re both fibrous. The quality of Fibreglass made it a good substitute once the health effects of Asbestos were deemed unacceptable. It also possesses the same desirable qualities as Asbestos, one being the heat resistance. More are referring to Fibreglass as the “man-made Asbestos”. Early research stated, “Fibrous glass of small diameter is potent chemical”.


Generally, fibreglass is considered safe (when installed properly). Once it is installed, fibreglass rests safely between panels and plaster- but when it’s removed the fibres will become airborne. People are now looking into another way of insulating their homes!
