High-Risk Asbestos Materials in Construction

Thermal Lagging and Pipe Insulation

Most thermal lagging, especially around pipework, contains high concentrations of brown asbestos, sometimes up to 80%. This is due to asbestos's exceptional thermal and water resistance properties.

Examples of Asbestos-Containing Insulation

• Flue Sections: Visible brown asbestos mixed in, shown in the provided image.
• Insulated Tanks and Pipes: Asbestos layers on green tanks and cream-coloured pipes.
• Boiler Systems: Extensive asbestos lagging from top to bottom.

Cement Flues and Wrap Insulation

Cement flues, particularly in poor condition, pose a risk due to the presence of asbestos. Wrap insulation, often damaged and deteriorating, can release asbestos fibres.

Asbestos Coatings

High-risk asbestos coatings were commonly used in steelworks and concrete beams. Photographs showcase the haphazard application of asbestos coatings, highlighting the potential for widespread contamination.

Loose Fill Insulation

The most hazardous form is loose fill insulation, consisting of 100% raw asbestos, used in walls, cavities, and lofts. Images illustrate how this material, resembling dust balls, poses a significant risk when disturbed.

Recognizing Potential Asbestos Contamination

When encountering materials that require fire resistance, water resistance, or sound insulation, there's a higher likelihood of asbestos presence. Always exercise caution and consider the potential for asbestos in older buildings.
