Designs for Steel Stud and Rainscreen Conditions
Rainscreen conditions represent a unique design challenge when it comes to maintain fire resistance ratings. Ventilation gaps and drainage critical to protect the structure from forming mold can just as easily allow for flame and smoke propagation floor to floor during a fire event.
STI offers a complete package of tested perimeter fire barrier designs that maintain fire resistance ratings without interfering with ventilation and drainage.

Curtain Walls are the most prominent aspect of any building and one of the most challenging elements to work with from a fire resistance perspective.Let our team of Curtain Wall and Facades Firestopping experts assist by reviewing your design and provide appropriate recommendations to ensure performance under fire without compromising on your design aesthetic.
Perimeter fire containment systems are tested according to ASTM E2307, "Standard Test Method for Determining Fire Resistance of Perimeter Fire Barriers Using Intermediate-Scale, Multi-Story Test Apparatus (ISMA)".
The ISMA structure is a two-story furnace that subjects a perimeter fire containment system to fire exposure from two sides simultaneously
One published design listing covers insulated spandrel panel, valance insulated panel, and zero spandrel/all vision glass designs that can be field or shop installed!
