Mechanical Electrical Plumbing

STI offers a variety of off the shelf and factory manufactured solutions that are up to the challenge of any MEP penetration. All our products meet or exceed the exacting parameters of ANSI/UL1479, ASTM E814, and ULC-S115.

  • Versatility of Intumescent Sealant
  • Eliminate Core Drilling with Cast-In-Place Firestopping
  • Electrical Outlet Protection
  • The 5/8" Solution Pioneered by STI
  • Acoustical Considerations
  • One Step Firestopping for HVAC Ducts

Versatility of Intumescent Sealant

Our SpecSeal® LCI Intumescent Sealant is used in over 500 Through-Penetration UL Firestop Systems with fire ratings up to 4 Hours. The wide breadth of testing makes LCI the go to solution for any MEP penetration. Only SpecSeal® LCI Sealant can span the range of conditions from simple single metal or plastic pipe or conduit penetrations to complex arrays of multiple penetrants all at the best installed cost.

Eliminate Core Drilling with Cast-In-Place Firestopping

Install SpecSeal® Cast-in Devices before you pour and make core drilling a thing of the past. SpecSeal® Cast-in Devices allow you to firestop during the concrete pour, eliminating the need to pre-form or core drill for each penetration. With SpecSeal® Cast-in Devices, you eliminate scheduling bottlenecks and free up installers to do what they do best without sacrificing code compliance.

Electrical Outlet Protection

STI offers excellent solutions for electrical outlet boxes, the most common penetrant on a typical construction project. SpecSeal® SSP Putty Pads, intumescent, non-hardening putty pads, are tested for 1 or 2 hour ratings on a wide variety of metal and plastic boxes with metal or plastic face plates. Our putty pads are formulates from 100% solids, butyl rubber to stay put and withstand the test of time. Codes, such as the IBC, allow the use of such products to reduce the horizontal separation of boxes to less than 24 inches or to accommodate boxes greater than 16 square inches.

STI’s SpecSeal® Series EP Box Inserts are intumescent pads that insert into the back of electrical boxes for situations where existing boxes are installed into the wall or where installation in the shop vs. the field may be more cost effective. The thin, supple pads do not significantly reduce available box volume, and in the event of fire, expand up to 60x to ensure ratings of 1 or 2 hour walls are maintained.

The 5/8" Solution Pioneered by STI

In gypsum board construction, many competitive products vary the thickness of sealant required dependent upon the hourly rating of the wall assembly. At STI, we pioneered the 5/8” depth solution. Whether 1 or 2 hour rated, our systems are consistent requiring 5/8” depth of caulk to eliminate confusions and costly mistakes.

Acoustical Considerations

All STI product are designed and tested to confirm their abilityto resist the passage of sound, following the parameters of ASTM E90. Sound Transmission Classification (STC) Ratings are an important consideration on many construction projects, and STI products and systems help maintain such ratings. Contact one of our Technical Service Engineers to learn more.

One Step Firestopping for HVAC Ducts

HVAC penetrations have always been a multi-step process of applying firestop sealant, waiting for inspection, then finishing with reinforcing steel angles and waiting for subsequent re-inspection. SpecSeal® FyreFlange Firestop Angle merges the fire resistive ability of a firestop sealant with the structural support of steel angles into one solution. With FyreFlange you can install and move on to the next condition without having to revisit each penetration multiple times.
