STI offers a variety of versatile and cost effective firestopping solutions for addressing Mechanical, Plumbing, and Electrical Penetrations through Fire-Rated construction. Intumescent firestop sealants like our SpecSeal® SSS and LCI Sealants are the go to products for individual or small grouped penetrations. While partnering SpecSeal® SSM Firestop Mortar with our Intumescent Wrap Strips and Firestop Collars make a cost conscious method of addressing oversized openings with a variety of plastics, cables and combustible insulations.
SpecSeal® Composite Sheet is an ideal choice when addressing oversized openings with a variety of penetrations like the tops of shafts. SpecSeal® Composite Sheet forms a robust permanent seal over large spans while providing a professional finished appearance. In tightly packed spaces where space between pipes is at a minimum nothing competes with the ease of installation of the SpecSeal® SSB Firestop Pillow. Available in a variety of sizes the SSB Pillows make short work of tight spaces allowing for installation from a single side of the assembly.
