Fire containment System for Valance Insulated Panel, Non-Backpan Designs.
We are excited to introduce the firestop industry’s first perimeter fire containment system for valance insulated panel, non-backpan designs. This cutting-edge design listing is a cost-effective, “all vision glass solution” that can be installed in the shop or on-site or as a new install method for traditional insulated spandrel areas.
- Cost-effective All Vision Glass solution that can be installed in the shop or on-site
- Allows lower section of spandrel area to be insulated for thermal or uninsulated
- Multiple spandrel types including vision glass, glass, stone, ACM, and MCP panels
- Designs allowing structural silicone in addition to pressure plate/gasket
- Anchor shielded from direct flame impingemen
- Class II or III Movement Capability - +/-5% Vertical Shear
- Less than 1 CFM L rated
- Specs call for minimum 3” thick 8 pcf faced or unfaced ROCKWOOL CURTAINROCK 80 insulation
- 2 Hour Rated
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!
STI manufactures two grades of elastomeric firestop coatings:
SpecSeal® AS Elastomeric Spray is a latex-based firestop spray formulated for high movement and rate of application
SpecSeal® Series FT Fast Tack Firestop Spray, a hybrid polymer coating designed for use in inclement weather
The Quick Clip™ Perimeter Fire Containment System is designed to accelerate the installation of curtain wall spandrel insulation. The system's unique U-brackets clip onto mullions without screws to support the curtain wall insulation. Self-locking fasteners secure the insulation panels in place.
