According to most building codes, brick is officially listed as “non-combustible.”
If an exterior fire starts from leaves burning, another house on fire or from some other source, brick will not burn. Fire will not penetrate brick walls from the outside.
In a one-hour severe fire test, brick withstood the flames. Fiber cement crumbled before the end of the test. And vinyl siding was completely destroyed in 18 minutes. Brick's one-hour fire rating protects your family better than any other non-masonry building material. Good for your safety. Good for lower homeowner insurance premiums year after year.
