Verdict
The Great Stuff 99112831 Smart Dispenser Fireblock is a solid option for those targeting large gaps and insulation around outlets and plumbing, with its expanding foam properties proving effective. However, it can be messy and presents challenges with its nozzle and tip usability. If you're searching for a more controlled application, consider testing the product on a smaller scale first to manage material usage better. Despite its drawbacks, it provides reliable insulation performance, especially for floor and wall applications.
