After the tragic fire that swept through London’s Grenfell Tower on June 14, killing an estimated 79 people, the British government ordered tests to be carried out on buildings across England with similar cladding.

Information is still coming out about what caused the fire and why it spread so quickly, but the initial belief is that cladding added during a recent refurbishment may have played a large role in causing the fire to spread. An ongoing criminal investigation will determine if the cladding complied with the relevant fire and building regulations.
