Tremco Sealants: where EPDs stand today

Who they are and what they sell

Tremco Sealants & Waterproofing sits inside Tremco CPG with a broad building‑envelope lineup. The range spans silicones and polyurethanes for glazing and weathersealing, self‑adhered and fluid air‑vapor membranes under the ExoAir brand, below‑grade and deck waterproofing, traffic coatings, transition membranes, and precompressed joint systems. Their site highlights LEED, GREENGUARD and Living Building Challenge alignment and provides a sustainability hub you can hand to design teams (Tremco Sustainability).

Breadth and depth of the catalog

Across these families, Tremco plays in several major categories rather than being a pure play in one chemistry. Think a dozen‑plus product families and hundreds of SKUs when you include sizes and colors. Examples on the membrane side alone include ExoAir 110, 110AT, 120, 130, 2000 and 230, each aimed at different permeability and application windows.

Current EPD coverage at a glance

Publicly visible, product‑specific EPDs tied to Tremco’s core U.S. sealants and ExoAir membranes appear limited as of December 2025. Within the wider Tremco CPG family, we do see EPD activity on sister brands. Illbruck has multiple façade membrane EPDs valid through 2030 and Nullifire publishes a verified EPD for its FB750 coated batt with a current validity window to mid‑2029 (Nullifire, 2025). Nudura also lists an ICF EPD under the International EPD System with validity into late 2027 (EPD International, 2027). Those are positive datapoints, but they sit adjacent to, not inside, Tremco’s U.S. sealants and air‑barrier flagships.

The gap that matters commercially

More owners and AEC teams now filter submittals for product‑specific, third‑party verified EPDs. If a sealant or membrane lacks one, the modelers drop in conservative defaults that can make a specifier skittish in tight carbon budgets. That does not mean the product performs worse in reality. It simply means the project team takes a penalty in their accounting, so a competitor with a ready EPD is easier to approve.

A quick “spec‑off” reality check

Pick a likely high‑volume Tremco product that shows up on many bids, for instance Dymonic 100 or Spectrem 1 on the sealant side, or ExoAir 230 on the membrane side. We could not locate public EPDs for those specific items on Tremco’s site or major EPD registries as of today. Meanwhile, direct or adjacent alternatives do exist with current declarations. Pro Clima’s SOLITEX ADHERO 3000 membrane carries a valid EPD published March 31, 2025 and running to March 31, 2030 (EPD International, 2025). Mapei’s Mapesil AC Zero silicone sealant shows a publication date of November 5, 2024 and validity to November 4, 2029 (EPD International, 2024). In several bid rooms, that single PDF is the difference between an immediate green light and a return‑to‑vendor.

Program rules are moving (in a good way)

If internal teams worry that “the PCR isn’t clear,” the rulebooks are catching up. The International EPD System transitioned Construction PCR 2019:14 from version 1.3.4 to 2.0.0 in 2025 and issued guidance on timing for new publications and maintenance updates into 2025 (EPD International, 2025). In North America, the Adhesive and Sealant Council engaged Smart EPD on June 20, 2025 to refresh the adhesives and sealants PCR used for building and construction, creating a cleaner on‑ramp for U.S.‑market EPDs (Adhesive and Sealant Council, 2025).

Competitive set Tremco meets most often

On sealants for glazing and façades, the usual cast includes Dow’s DOWSIL, Sika, Pecora and Soudal. In air and water barriers and liquid flashings, Henry (Carlisle Weatherproofing Technologies), Prosoco and Pro Clima appear frequently. For passive fire protection, Nullifire is already in the Tremco CPG family. Many of these brands list current EPDs across membranes, tapes, or silicones that show up on envelope specs, which is exactly where Tremco’s core U.S. portfolio could gain ground by publishing enviromental declarations of its own (EPD International, 2025).

Where to start if you’re prioritizing SKUs

Aim first at the handful of products that drive most of the revenue and most of the submittals. For Tremco, that likely means one high‑runner silicone, one high‑runner polyurethane or hybrid, and one fluid air‑barrier grade. Choose the PCR that matches your buyer’s expectations and your competitors’ format, then keep it simple on the first pass. Gather one solid reference year of plant energy by carrier, packaging weights, yields per cartridge or pail, and realistic installation scenarios. The right partner will do the cross‑plant data wrangling and set you up to rinse‑and‑repeat across the line without burning internal time.

What this means for sales

A single product‑specific EPD often unlocks an entire segment of projects that would otherwise pass you by. Sales teams rarely log the deals they never pursued because of missing documentation, which is why the ROI on the first three or four EPDs can be bigger than it looks on paper. Publish where the spec friction is highest, keep renewals on a tidy calendar, and use the first wave as a template for the rest of the catalog.

Closing thought

Tremco has the breadth to win whole‑envelope packages. Translating that reach into a visible, current set of EPDs for its marquee sealants and membranes would make project teams’ lives easier and reduce substitutions when carbon targets are tight. The playbook is straightforward. Pick the right PCR, prioritize the top movers, collect once, publish fast, then scale.
