The gypsum wallboard was covered which has a primer and cover coats of latex paint. This analyze focused on the results where the paper were burned absent (consumed) and where the paper were peeled up (penetration). To accomplish this, the scientists evaluated the variability of the flame top compared to the height and location of injury.
