How to Install Fireblocking (Without Setting Your House on Fire!)
4. Practical Tips for a Successful Installation
Alright, let’s get practical. Installing fireblocking isn’t rocket science, but it does require some attention to detail. First and foremost, safety first! Wear appropriate safety gear, including eye protection and a dust mask, especially when working with insulation or cutting wood. No one wants a face full of fiberglass!
Before you start, thoroughly inspect the areas you’ll be fireblocking. Identify any gaps, holes, or penetrations that need to be sealed. Measure these openings carefully to ensure you cut your fireblocking materials to the correct size. A snug fit is key to an effective fireblock.
When using lumber or plywood, cut the pieces to fit tightly into the openings. You may need to use shims or wedges to ensure a secure fit. Remember, the goal is to create a solid barrier that prevents the passage of fire and smoke. You’re aiming for “airtightish,” not “perfectly airtight,” but close is good.
When using fire-rated caulk or sealant, apply it liberally around pipes, wires, and other penetrations. Make sure to fill all gaps and cracks completely. Follow the manufacturer’s instructions for application and drying time. And don’t skimp! Using a good quality caulk will last longer and seal better.
Finally, double-check your work. Ensure that all gaps and openings are properly sealed and that the fireblocking materials are securely in place. It’s better to spend a little extra time now to ensure the job is done right than to regret it later in the event of a fire.
