Asbestos is a group of naturally occurring minerals that are composed of thin, fibrous crystals. Because of these characteristics, asbestos was once widely used in construction materials due to its properties that made it heat resistant, durable and fireproof. Some of the most common products that may contain asbestos include:

• Insulation materials
• Ceiling tiles
• Roofing materials
• Floor tiles
• Adhesives and sealants
• Heating and cooling systems

While asbestos was banned in the UK in the year 1999, many properties built before then still contain products that may contain asbestos. These materials are generally harmless if they are in good condition and not disturbed, but if they are damaged or begin to deteriorate, they can release asbestos fibers into the air, which can be harmful if inhaled.
