Asbestos encapsulation is often needed to ensure the wellbeing of people in commercial and industrial environments.
During the 50s through to the 80s asbestos was extensively used in British Building programs.At this time asbestos was perceived as a product that could provide a cheaper method of fire and insulation protection.Used in the main for building of industry s and health service s structures. During the 90s it became apparent asbestos if disturbed could cause major health issues. In 1999 ACM( asbestos containing materials) and banned.
It is now apparent that exposure to ACM s could cause extreme respiratory problems which only manifest themselves years after exposure to disturbed structures containing asbestos.
The majority of ACM s we are asked to survey are roof and cladding sheets. These materials were used widely ,estimated over 1.5 million properties in industry with content in walls and roofs. Many organisations alleviate the problem by removing or disposing with licensed contractors. This is extremely costly and laborious.
The Health and Safety Executive say in Control of Asbestos Regulations 2012 "if ACMs are in reasonable shape and aren’t possible to damage, they could be left in situ, their state monitored and assessed to make sure they aren’t moved."
HSE state encapsulation or immersing in ACMs that are in reasonable state are viewed to be non licensed installation ,which is why asbestos encapsulation is being used more prevalently.
Many buildings have been encapsulated with closed cell polyurethane insulation with asbestos issues. Therefore solving the problem and preventing condensation at the same time. The application is sprayed onto the inside membrane of substrate at a depth of 25mm or greater if a u value is required. Polyurethane insulation is applied in liquid form and solidifies in 60 seconds to form a solid but pliable barrier.
This seals in fibres and deters exposure all together. At the same time it ceases the degradation of the underlying asbestos. So as well, it stops the release of dangerous fibres but it also gives high u values, reducing your thermal footprint and increasing efficiency. Obviously this enhances the ECO/Green credentials of the building. Our system is BBA and Fire Regulated,it’s fast and accesses difficult areas as well as makes the structure air tight where applied.
External applications can also be carried out on cement asbestos roofs and walls when they become exposed for long periods to the elements. These structures erode over the years and become victim to extensive thermal movement meaning leakage and asbestos fibre disturbances. Our polyurethane and elastomeric coating method weatherproofs the structure, does the core job of encapsulation, reduces your carbon footprint and gives exceptional thermal performance.
