Asbestos was used in many construction materials between 1930-1990. It was used so heavily due to its plethora of properties making it durable and resistant to heat, electricity and corrosion, that it was perfect for insulation.
One key property of asbestos which was unknown until its ban in 1999 was that it is also a nasty carcinogenic material. When inhaled, asbestos fibres cannot be broken down by the body, and over many years these fibres cause chronic inflammation, scar tissue and eventually can develop into an incurable cancer (mesothelioma), lung cancer, asbestosis or plural thickening.
While asbestos can be a dangerous material, it only poses a risk to health when disturbed or during deterioration. If the asbestos product is in good condition and not disturbed then there is no need to worry. For further information on asbestos visit https://www.hse.gov.uk/asbestos/
The risk comes when asbestos is unknowingly disturbed by homeowners or tradesmen. It is very difficult to identify asbestos with the naked eye, so it’s very easy for homeowners to mistake, for example, an asbestos insulation board for harmless plasterboard. This is why testing for asbestos before carrying out renovation works is very important.

S – Asbestos cement panels T-Roofing felt
Drilling into an asbestos insulation board would release thousands if not millions of tiny asbestos fibres (you can fit 20,000 fibres on the head of a pin).
These fibres can easily be inhaled and will contaminate everything around it. Not only is this very dangerous to health, it’s also a very expensive mistake to rectify (It would require decontamination and an environmental clean of the whole room and any adjoining rooms potentially).
Precautions Before Renovations
If your house was built pre-2000 and you’re thinking of carrying out renovations which could disturb any construction materials, then have the area tested before disturbing – this could save you thousands of pounds in damage and help you avoid exposure to dangerous levels of asbestos.
If you’re going to be doing a full renovation on a house then getting an asbestos survey is your most sensible option to ensure any asbestos is identified.
