Firestopping

In commercial construction, firestopping isn't optional. It's life-saving.


Sawtooth Fortified installs UL-tested and approved firestopping systems that prevent fire and smoke from spreading through wall penetrations and joints, giving occupants valuable time in emergencies.

Safety You Can Count On


  • Mechanical and electrical penetrations
  • Top-of-wall joints
  • Slab edge and curtain wall systems
  • Complex commercial and healthcare facilities

Firestopping Done Right

In commercial construction, few elements are as critical as firestopping. A poorly sealed penetration can allow fire, smoke, and toxic gases to spread rapidly – threatening lives and property within minutes. At Sawtooth Fortified, we take this responsibility seriously. Over the last 5 years, we've partnered with general contractors, owners, architects and consultants to install firestopping systems that meet the highest standards of safety and compliance.

Our work isn't just about passing inspections. It's about protecting people, preserving assets, and giving owners peace of mind that their buildings are built to perform under the most demanding conditions.

Northside Electric has had the pleasure of working with Sawtooth on numerous commercial projects over the past few years. Their expertise in firestopping, caulking, and waterproofing has consistently delivered high-quality results, meeting tight schedules and strict standards. The Sawtooth team is professional, reliable, and a true partner in ensuring our projects succeed.

This horizontal construction joint is backed with mineral wool and sprayed with STI AS200. AS200 is an elastomeric firestop spray that accommodates high dynamic joint movement while having the ability to hold up to a 4-hour rating. Due to this condition being exposed, our team took the time to tape and mask, ensuring a clean and smooth appearance.
