What type of cladding was used at Grenfell?
The cladding used on the Grenfell Tower was Metal Cladding. This is usually used in Commercial Buildings and Factories. It is one of the most durable claddings available in the market. This type of cladding has changed the way buildings look and gives them a hi-tech edge.
What is an MCM panel?
MCM (Metal Composite Material) consists of two metal cover sheets and a fire rated core. The commonly used metals are Zinc, Stainless Steel, Copper or Aluminum Plate but other specialty metals are available.
What are ACM and MCM panels?
Introduced more than 50 years ago as aluminum composite material (ACM), this product category evolved into metal composite material (MCM), reflecting the inclusion of natural metal skins such as zinc, copper, stainless steel, and titanium.
Who made Grenfell cladding?
Arconic, formerly known as Alcoa, supplied the Reynobond 55 cladding panels with a polyethylene (PE) core that were used in the refurbishment of Grenfell Tower, and were later found to have fuelled the blaze which claimed 72 lives.
What type of cladding is banned?
Ministers have announced plans to outlaw the use of metal composite material panels with an unmodified polyethylene core (MCM PE) as part of an overhaul of building regulations and guidance, which will come into effect on 1 December.
Which cladding is flammable?
While there are numerous types and brands of cladding available, there are 2 types of combustible cladding that may pose a risk for building occupants, as well as the community more broadly. These are: aluminium composite panels or ‘ACP’ expanded polystyrene or ‘EPS’
What is Category 3 ACM cladding?
ACM with an unmodified polyethylene filler (category 3) with any type of insulation presents a significant hazard on buildings over 18m and should be replaced.
What type of insulation was Grenfell?
Celotex’s RS5000 boards were the primary insulation material for Grenfell Tower. The boards are made from a combustible plastic called ‘polyisocyanurate’, which lets off toxic gases including cyanide when it burns.

Do all flats need an EWS1 form?

What is PE cladding?
Most aluminium composite cladding consists of a layer of plastic sandwiched between two aluminium sheets. And it’s the plastic layer, usually made of polyethene (also called polyethylene), that’s the main culprit. Polyethene isn’t only found in cladding — not by a long shot.
What is WPC cladding?
WPC is a blend of wood powder and virgin polymers which provides its product applications excellent dimensional stability and green ratings. However, the WPC Cladding Solutions are prepared from fillers, pigments, stabilizers, and recyclables.
