Specifiers love clean details that move when buildings do. JointMaster, the expansion joint systems brand associated with Inpro, is a familiar name in airports, hospitals, arenas and big‑footprint commercial work. Here is how their product range stacks up, and where Environmental Product Declarations (EPDs) are a ready lever for more specs won.

Where JointMaster plays

JointMaster focuses on expansion joint solutions that bridge building movement at floors, walls, ceilings and exterior envelopes. The lineup spans cover-plate systems, compression and foam seals, wide seismic systems, and life‑safety add‑ons like fire and moisture barriers. It shows up wherever traffic, thermal drift or seismic design requires controlled, durable movement joints.

Product range in plain English

Across the catalog you will find floor systems such as the 151, 221, 401 and 516 series, heavy‑duty vehicular options like the 721 family, plus reinforced vapor barriers and related life‑safety components. Taken together the range covers several application categories, with series counts in the dozens and resulting size and finish permutations comfortably in the hundreds. That breadth fits healthcare, aviation, higher‑ed, stadiums and parking structures.

EPD coverage, today

Based on a current scan of public EPD listings, we could not find product‑specific EPDs for JointMaster expansion joint cover assemblies as of December 19, 2025. The same is largely true for close competitors in this niche, which suggests a category‑wide gap rather than a single laggard. Translation, a first mover can set the reference point specifiers use.

Why this matters in specifications

When a project team must account for embodied carbon, picking a product with a third‑party verified EPD avoids defaulting to conservative database factors that can make a solution look worse on paper than it performs in reality. Under evolving owner policies and rating systems like LEED v5, product‑specific EPDs keep options open in tight material screens and reduce the risk of being value‑engineered out late in design.

A likely best seller without an EPD

Consider bread‑and‑butter floor systems such as the 151 Series or 221 Series. These are common choices in corridors and lobbies with movement in the 25 to 50 percent range, yet we do not see public, product‑specific EPDs for these assemblies today. On projects with strict transparency lists, that absence can push a team toward a competing solution that brings verified data, even if performance is similar.

Who JointMaster competes with on projects

Expect to see MM Systems, Balco, Nystrom, Sika EMSEAL, Watson Bowman Acme and the expansion joint group at Construction Specialties on the same bid lists. Many of these firms mirror JointMaster’s breadth across floor, wall and exterior covers, seismic options and fire or moisture barriers. The EPD gap appears industry‑wide for cover assemblies, which turns an EPD program into a simple differentiator.

The fast path to an EPD here

Expansion joint covers are multi‑material assemblies that combine extruded aluminum or stainless steel, elastomeric seals and sometimes mineral wool, intumescent or textile fire modules. There is no single, universally dominant Part B PCR for this exact assembly in North America right now, so teams typically choose an accepted construction products rule that peers have used for analogous systems, then document bill‑of‑materials, regional sourcing, and plant energy as the reference year. A partner who handles internal data wrangling across purchasing, machining and assembly lines makes this painless and quicker than most expect.

Sustainability signal from the parent brand

While product EPDs for JointMaster covers are scarce, the corporate sustainability footing behind the brand is notable. Inpro’s Muskego facility achieved an independently verified 63.99 percent waste diversion for 2023 under the SCS Global Services Zero Waste Program, with a published certificate code SCS‑ZW‑0030 (SCS Global Services, 2025) (SCS Global Services, 2025). The company also received a 2025 Recycling Excellence Award from the Wisconsin DNR for its overall program, reinforcing a culture that can support credible product transparency at scale (Wisconsin DNR, 2025).

If you are mapping a roadmap, start with high‑runner series in floors and exterior conditions, then extend to seismic and fire‑rated variants. The first published EPDs in this category will become the yardstick others must match. Dont wait for competitors to set your benchmark.

Frequently Asked Questions

Does JointMaster currently publish product-specific EPDs for expansion joint cover assemblies?

As of December 19, 2025, we could not locate public product‑specific EPDs for JointMaster cover assemblies. The same appears true across several primary competitors, which signals a category‑wide opportunity rather than an isolated gap.

Which JointMaster product families are most common in specifications?

Floor systems such as the 151, 221, 401 and 516 series are common in healthcare and commercial corridors. Heavy‑duty vehicular systems like the 721 family appear in parking and arena work. Fire and moisture barriers round out life‑safety needs.

What is the business case to create EPDs for expansion joint systems now?

Early EPDs set the precedent for future comparables and keep products in play on owner lists that screen for verified disclosures. Teams avoid penalty factors from generic databases, and sales avoids late‑stage substitutions tied to missing transparency.

If there is no dedicated PCR for expansion joint cover assemblies, how do teams proceed?

Pick a widely accepted construction product PCR used by analogous assemblies, document a clear bill of materials and manufacturing footprint, then verify with a recognized program operator. This is routine, even when a niche Part B PCR does not exist.

Where can I find a sustainability page related to JointMaster’s parent brand?

Inpro publishes a sustainability update on waste diversion with details on its SCS Zero Waste certification here, which is helpful context for future product transparency: Waste Diversion.
