What OBEX just published
OBEX released six product‑specific EPDs across its CORTEX line, covering interface sealing membranes, EPDM membranes, paste adhesives, and one hybrid cement board. Publication month for the first in this set is April 2025. The program operator of record is EPD Hub.
Scope matters. These are product‑specific declarations that map to real SKUs used around windows, doors, curtain walls, and SFS interfaces. For specifiers, that means fewer substitutions and faster whole‑building LCA checks when envelope details get tight.
Why this portfolio matters now
Envelope sealants and membranes often trip projects into generic, pessimistic carbon assumptions. With verified numbers on adhesives and membranes, OBEX products can stay in play when teams need third‑party data rather than claims. Think of it like switching from rumor to replay review during crunch time.
Competitive snapshot
Illbruck already lists multiple current EPDs for window and façade membranes through Smart EPD, so membrane buyers know what “good” looks like. See the quick take here: Illbruck, in focus.
SIGA shows a smaller public set of membrane and vapor‑control EPDs with IBU, which signals activity but not full coverage across its catalog.
Sika UK posts at least one EPDM membrane EPD with IBU for its SikaMembran line, which gives contractors a recognized alternative in certain markets.
Taken together, OBEX has entered the transparency arena with credible coverage right where façade packages make or break. In head‑to‑head membrane specs, they are catching up to established players, not chasing shadows.
The basics, translated for sales and PMs
- Product‑specific EPDs reduce the use of conservative defaults in LCA models, which can help products clear carbon screens without getting squeezed on price.
- Having adhesives and membranes covered in the same family shortens submittal ping‑pong, since adjacent materials in a detail now carry matching paperwork.
- If a GC asks “is it verified,” the answer is yes. EPDs are published by a recognized operator and align to EN 15804 and ISO 14025 conventions.
Where to find the paperwork
OBEX has begun listing EPDs directly on product pages. Example: the CORTEX 0771FR Paste Adhesive page includes an “Environmental Product Declaration” link for fast downloads (OBEX 0771FR). We recommend adding clear EPD links on every relevant membrane, adhesive, and board page, plus a central sustainability hub. Visibility is key for speedy submittals and fewer substitutions. It’s definately worth the 10‑minute CMS update.
What to watch next
Three practical moves will keep momentum high. First, extend coverage to any remaining high‑volume adhesives or membrane variants so entire interface details are consistently documented. Second, mirror links in distributor libraries and BIM objects to cut search time. Third, track PCR updates at the operator level so the next renewal lands on current rules without a scramble.
Bottom‑line signal
OBEX’s first‑ever EPDs give façade and glazing teams spec‑ready data in categories where it matters most. Competitors like Illbruck, SIGA, and Sika are active, yet this debut puts OBEX on equal footing in the details that decide bids. That is how a transparency step turns into more shortlisted packages and fewer last‑minute swaps.
