Fireblocking is required and very important for your home. Fireblocking is a method used to seal vertical openings in concealed spaces behind the walls, floors, and ceilings to block flames from spreading fast through your home. This allows you and your family more time to escape in the event of a fire. (See example of fireblocking above.)
The pre-drywall phase of your new construction is your only chance to see if fireblocking is properly installed or missing. Once the walls go up, hidden gaps can’t be checked.
