STI Firestop: products, scope, and the EPD gap
Specified Technologies Inc. is a pure‑play firestopping brand with broad penetration, joint, curtain wall, and pathway solutions. The product range is deep. Their environmental paperwork appears thinner. Here is a crisp view of what they sell and how their EPD coverage stacks up, so product managers can decide where to move first.
Who they are
Specified Technologies Inc. (STI Firestop) focuses solely on passive fire protection. Their engineering team and training footprint are prominent, and they publish tools, UL system support, and LEED letters on their site. See their overview and engineering services on STI’s About us.
What they sell, at a glance
STI’s catalog spans penetrations, construction joints, curtain wall perimeter systems, smoke and acoustical sealants, fireblocking, protective wraps, and cable pathway devices. Think classic firestop sealants and sprays, intumescent collars and wraps, pillows, putties and mortars, coated batts, endothermic wraps, and EZ‑Path cable pathways. Across these families, SKUs run into the hundreds, with dozens per major category.
Are they a pure play or diversified?
Pure play. Everything centers on firestopping and adjacent passive fire protection. That specialization shows in breadth of systems and application support for healthcare, data centers, education, offices, and industrial projects.
EPD coverage today
As of December 19, 2025, we could not locate any current, third‑party verified Environmental Product Declarations publicly listed for STI products with major program operators. If STI has a newly issued EPD not yet visible in public operator libraries, we’re happy to be corrected, but public discoverability matters for specs.
Why that matters commercially
Architects and contractors chasing low‑carbon targets or LEED v5 disclosure credits often default to products with product‑specific EPDs. Without one, teams must rely on generic or penalized assumptions in their carbon accounting, which can quietly push a product out of contention even when performance is great. Getting a product‑specific EPD removes that hidden handicap so the conversation shifts back to fire performance, install speed, and total cost.
A likely first move: sealants
STI’s workhorse lines include intumescent and acrylic firestop sealants such as SpecSeal SSS or LCI. Those are classic best‑sellers in penetrations and construction joints, yet we don’t see public EPDs for them. Several direct competitors do publish EPDs for comparable sealants and systems, which means they are more plug‑and‑play for projects that score or prequalify using disclosure.
- Example competitor coverage: Hilti’s FS One Max firestop sealant has a verified declaration with EPD Hub dated June 17, 2025, valid to 2030 (EPD Hub, 2025) citeturn2search0.
- Example competitor coverage: Nullifire’s firestopping systems and intumescent range carry current EPDs registered with Environdec, including the FZ100 system, valid to December 3, 2029 (Environdec, 2024) citeturn1search10.
If a submittal asks for product‑specific EPDs, those SKUs can be selected without extra paperwork or substitutions. That is where STI might be loosing out most frequently in tight specs.
Product range depth and where EPDs would pay back fastest
- Penetration sealants and sprays used daily by electricians and plumbers. High run‑rate, high spec visibility, easy to model from existing plant data.
- Coated batts and modular blocks used in cable trays and busier risers. These often appear in owner standards and data‑center playbooks, so an EPD shows up in every bid package.
- Collars, wraps, and endothermic wraps in mechanical rooms and shafts. Volumes are lower, but EPDs help land complex alternates where like‑for‑like comparisons are scrutinized.
Start with one high‑volume sealant and one high‑visibility system component. That two‑SKU strategy covers most daily details and the big show‑and‑tell photos in a submittal. It is also an efficient data collection sprint.
Competitors you’ll meet on the same drawings
- Hilti for sealants, blocks, sleeves, collars, and wraps, with a growing list of EPDs across firestop and fastening categories (EPD Hub, 2025) citeturn2search0.
- Tremco CPG’s Nullifire line for coated batts and intumescents, with multiple EPDs in Environdec (Environdec, 2024) citeturn1search10.
- 3M for legacy fire protection in certain markets, plus distribution muscle.
- Regional brands that publish EN 15804 EPDs for acrylic or silicone fire‑rated joint sealants, giving local bidders a quick disclosure box‑tick (Environdec, 2025) citeturn2search1turn2search2turn2search6.
Where to find STI’s stance on sustainability
STI’s site highlights engineering quality, training, LEED letters, and process discipline, including participation in UL’s Technical Evaluation Developer Program. That quality story resonates. A dedicated sustainability or EPD page would make it easier for specifiers to confirm enviromental credentials on deadline. Their About us page is the best current entry point for LEED documentation.
What a strong EPD plan looks like for STI
Pick the PCRs competitors already use for firestop sealants and coated systems so specifiers see a comparable basis. Capture one recent full production year per plant, then model variants as additional scenarios. Publish with a mainstream operator, keep PDFs easy to find from each product page, and add the EPDs into submittal builder downloads. That makes the disclosure truly usable in the field. Do that and the ROI shows up quickly in fewer substitution fights and cleaner yeses from owners chasing portfolio‑level carbon goals.
Bottom line
STI is definately competitive on application depth and engineering support. Adding product‑specific EPDs for a few flagship SKUs would align that strength with how projects are scored and awarded in 2026 specs. It is a small lift for a big commercial unlock.
Frequently Asked Questions
Does STI Firestop currently have public EPDs specifiers can download?
As of December 19, 2025, we could not find current, public EPDs for STI products in major operator libraries. If a brand‑new declaration exists but is not yet listed publicly, teams may still face delays in submittal acceptance without a linkable document.
Which STI product types would benefit first from EPDs?
High‑volume intumescent and acrylic sealants, plus coated batts or modular blocks used in cable and MEP penetrations. These SKUs appear on most details and submittals, so disclosures have immediate spec impact.
Do competitors publish EPDs for equivalent firestop products?
Yes. Examples include Hilti FS One Max with a 2025 EPD in EPD Hub (EPD Hub, 2025) citeturn2search0 and Nullifire systems with valid Environdec registrations through 2029 (Environdec, 2024) citeturn1search10.
