Asbestos

Legh Richardson
I have been watching the parliamentary select committee regarding the independent review of building regulations which included specifically cladding of buildings to provide suitable insulation and fire proection. It appears from the statements given by the witnesses called that all cladding known materials do not provide the necessary protection against combustion and toxic release under certain or even most circumstances.

Do you think there is a place now for the reintroduction of asbestos as a cladding on high rise buildings being non combustible as this appears to offer reasonable insulation as long as protection can be provided against damage and flaking ?

    Legh Richardson:



    "steel and mineral wool cladding is pretty well totally incombustible" --- I witnessed a building collapse while on fire due to the failure of the steel RSJs. So although steel may be fire resistant it will buckle under the heat generated from a full scale blaze.

    Sure - but we were discussing cladding rather than the building frame 


    Structural steel framing can be readily provided with material cover such that they don't suffer premature or disproportionate collapse in fire - ranging from over-boarding products to paint or spray on intumescent coatings (some of which can be applied at manufacture to ensure consistency and quality)


    I would be fairly happy to take a concrete structure such as Grenfell and apply steel and mineral wool cladding to improve thermal performance and aesthetics (coupled with appropriate cavity barriers) and be reasonably assured of it's ongoing safety in fire conditions.
