What Is Asbestos Overcladding for Roofs

A naturally-found mineral, Asbestos is made up of soft and flexible fibres resistant to heat, electricity and corrosion.

The mineral is added to many materials such as paper, cement, and so on to make it firmer and more robust. Although, over the years, its impact on human health and the environment has come to light. 

Since the exposure is highly toxic, the use of the substance has been made illegal in many countries worldwide.

Asbestos Overcladding for Roofs in Brief

It is a very cost-effective roof restoration process that greatly reduces the mess at the site. Overcladding also reduces the mineral’s layer’s expensive disposal that needs to go back to the legal landfill.

You must provide a sheet of insulation while covering your asbestos cement roof to satisfy the legal regulations. 

The process begins by fixing the structure required to hold the metal plates, which are placed directly to the support below the cement layer. 

The structure is then insulated to support the new roof layer, followed by placing the metal sheet.

Warrington asbestos overcladding for roof offers many advantages too.

You won’t lose any extra revenue since the process involves minimal site disruption.

Enhances the overall energy efficiency by stopping damps and draughts.

Types of Asbestos

Asbestos is an umbrella term that refers to a group of minerals. The classification is as follows:

Chrysolite

Present in the modern-day walls, ceilings, floors and roofs of many businesses and house, White Chrysolite Asbestos is the most often used group of Asbestos. It has a very high resistance to heat.

Tremolite 

This type is a prime risk to health and considered a significant polluting substance in items consisting of Asbestos.

Actinolite

Although Actinolite is very rarely made use of, this type is present in asbestos-containing products. 

Crocidolite

Crocidolite is the extensively toxic group of Asbestos, owing to its very minute fibres that can be inhaled and stashed in the lungs’ lining. Also known as “Blue Asbestos”, this category is one of the most efficient heat resistants.

Anthophyllite

When it comes to its commercial usage, this category has to be one of the least common forms of Asbestos. Traces of Anthophyllite can also be found present in White Asbestos, Talc and Vermiculite.

Amosite

In the past, this category in the cement industry and insulating pipes. The needle-like anatomy of its fibres endows it with moderately high heat resistance and tremendous tensile strength.

Conclusion

Given the nature of its harmful and toxic components and the whole legal aspect, it is better to hire professional help.
