PVC/uPVC or vinyl cladding products usually have a fire rating of C or D, which means this type of cladding is combustible. For comparison, most untreated wood cladding products have a fire rating of D.

Is cladding a fire risk?

When combustible materials are used for cladding or when materials are applied in the wrong way, there are increased risks regarding fire safety. But luckily, when you make the right choices, facade cladding is a completely safe option.

Which cladding material is flammable?

Aluminium composite panels (ACPs), as used at Grenfell, containing a polyethylene core can be highly flammable. High-pressure laminate (HPL) cladding, which is also widely used on high-rise buildings, is at least as flammable.
