Series SSS Latex Intumescent Sealant

SpecSeal® Series SSS Sealant is a latex based, high solids firestop compound. This material, when properly installed, will effectively seal penetration openings against the spread of fire, smoke, toxic gasses and water.

SpecSeal® Series SSS Sealant features STI’s patented and proprietary two-stage intumescent technology. When exposed to high temperatures or fire, this material expands aggressively in a highly directionalized fashion to quickly close off voids left by the burning or melting of combustible materials.

SpecSeal® Series SSS Sealant’s unique multi-viscosity formula yields a single grade that has excellent caulking properties as well as high build properties on vertical or overhead surfaces. This single grade may be pumped, caulked (standard cartridge or bulk loaded), knifed or troweled. In addition, SpecSeal® SSS does not contain PCB’s or asbestos.

Series PEN300 Silicone Joint Sealant

Pensil® 300 Silicone Sealant is a one-part neutral curing silicone sealant exhibiting superior performance in applications where sealing apertures in walls and floors are needed to control the spread of fire, smoke, toxic gasses, and water during fire conditions. Pensil® 300 Silicone Sealant reacts with atmospheric moisture to form a tough durable seal that will adhere to most building substrates without the use of primers. Pensil products do not contain asbestos or PCBs. Pensil 300 Silicone Sealant may also be used to seal vertical and horizontal joints between metals, masonry, concrete and other common construction materials.

Series PEN200 Two-Part Silicone Foam

Pensil® 200 Firestop Foam (PEN200) is a two-component RTV silicone foam that features excellent crack-and-void filling capabilities. Unlike other foams, PEN200 exhibits uniform cell structure, assuring reproducible, smoke-tight, fire resistant installations. Minimal pressure during foaming virtually eliminates shrinkage of the cured material. The elastic properties of the foam readily accommodate minor vibration of the pipe, conduit, etc. without loss of system integrity. Used in a 1:1 mix ratio, PEN200, when properly mixed, expands to approximately 4 times its original volume, filling available spaces and forming an effective barrier against fire, smoke and water penetration.

Series SSM FireStop Mortar

SpecSeal® Firestop Mortar is an economical, light-weight portland cement-based firestop product. This passive (non-intumescent) material utilizes a combination of heat sinking and insulating properties to provide an extremely high level of fire resistance. SpecSeal® Firestop Mortar mixes with water to form a non-shrinking, high yield mortar that may be applied by pouring, pumping, or troweling. Its low density and light weight means that less forming as well as less forming support is required. Its low density also makes re-penetration for retrofitting a simple task. SpecSeal® Firestop Mortar is designed to dry quickly and will not crack or spall due to freezing or changes in temperature.

Series SSB FireStop Pillows

SpecSeal® Firestop Pillows are through-penetration firestop products resembling small cushions or soft bricks. These intumescent and highly resilient pillows are installed in openings by compressing and stacking into the opening in a brick-like fashion.  SpecSeal® Firestop Pillows consists of a mineral fiber core material sealed with a water-resistant intumescent membrane. This coated core material is then heat-sealed in a tough, nonirritating, fire-retardant poly bag.

Series SSC Intumescent Collars

The SpecSeal® Firestop Collar is a factory-manufactured device designed to protect plastic pipes penetrating fire-rated walls and floors. Utilizing a heavy gauge galvanized metal collar to house a molded intumescent insert, the SpecSeal® Collar is specifically sized to fit 1-1/2", 2", 3", 4", and 6" trade sized pipes.  This product utilizes STI’s patented two-stage intumescent technology, providing a very responsive and highly directionalized expansion. Expansion is extremely fast, providing quick closure for burning combustible pipes.  When exposed to temperatures in excess of 250F (121C), the SpecSeal® Collar’s molded insert begins to expand (intumesce) rapidly to form a dense, highly insulative char. Its free expansion ranges from 16-24 times original (pre-expanded) volume. Expansion continues up to 1,000F.

Series LCC Intumescent Collars

The SpecSeal® Series LCC Firestop Collar is a factory-manufactured device designed to protect plastic pipes penetrating fi re-rated walls and fl oors.
