You cover your building with styrofoam and then you're shocked when it goes up like a Roman torch.
In Toronto, the exterior of a house that is within 1 or 2 meters of the neighbouring house must have noncombustible cladding. This means you can use cement board, aluminium siding...or, flammable and toxic vinyl siding....why? Because the vinyl siding industry lobbied the city and paid off a few politicians. The risk to life safety is trumped by money in the pocket.
