Pros

  • โ€ขEffectively seals plumbing, pipe penetrations, and large holes.
  • โ€ขExpands significantly to fill gaps, ideal for varied applications.
  • โ€ขEnsures safety with no reported fire incidents since use.
  • โ€ขReliable for indoor and outdoor insulation, especially around outlets and lights.
  • โ€ขProvided in a noticeable orange color, making application visible.

Cons

  • โ€ขDifficult to control when applying to ceilings; may require expertise.
  • โ€ขMessy foam results in waste, similar to other foam insulations.
  • โ€ขNozzle and tip issues, including breakage and clogging.
  • โ€ขFlow inconsistencies, even with adjustments.
  • โ€ขThe 'no drip' feature is ineffective as tips tend to leak.
  • โ€ขNot reusable; users find the tipped product from stores more efficient.

Bottom Line

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.
