Bravo, Kouruset’s first EPDs are live

What dropped in October

Kouruset has published three Environmental Product Declarations for its Vesiset balcony water‑control line. The debut wave landed in October 2025, with an additional declaration following in November. All three are verified and published by EPD Hub.

The scope at a glance

The release covers the core portfolio specifiers actually touch:

• Stainless steel–based Vesiset balcony drainage systems (product family coverage).
• Aluminium‑based Vesiset balcony drainage systems (product family coverage).
• Vesiset throw‑out pipes for direct slab discharge (component‑level coverage).

In plain terms, that spans both interior and exterior balcony drainage approaches plus the common spout detail used on precast slabs. Validity runs into late 2030, giving teams a long runway to reference these in submittals.

Who Kouruset serves, and why the timing matters

Kouruset designs and supplies balcony water‑control systems for mid‑ and high‑rise residential, with deep roots in Nordic precast workflows. EPDs make those choices easier in markets where project teams now expect product‑specific data instead of conservative defaults. It flips a frequent spec penalty into a level playing field and helps avoid last‑minute swaps when carbon budgets bite under LEED v5 and similar owner requirements.

Competitive read in this niche

• Vieser Oy, another Finnish drainage name, shows multiple current EPDs for floor and linear drains in EC3, so transparency is already in their toolkit for interior wet‑area drainage.
• Lindab carries EPDs for rainwater systems and ventilation components that often intersect façade water paths, including Rainline and recycled‑content lines.
• Traditional balcony drain brands frequently seen on drawings, such as HL Hutterer & Lechner, Loro, and Sita, did not return current balcony‑drain EPDs in EC3 at the time of writing. That leaves room for Kouruset to define the category standard on balconies specifically.

Net effect. Kouruset has entered the transparency arena where some adjacent players are active but many balcony‑specific alternatives still lack published EPDs. That is a tangible visibility edge in multifamily specs.

Program operator and rules

The declarations sit with EPD Hub and align to EN 15804+A2 and ISO 14025, the rulebook combo most European design teams expect. One quick benefit is consistent formatting across the family EPDs, which speeds up reviewer checks and keeps apples‑to‑apples comparisons clean.

Where to find the documents

Kouruset has begun surfacing the EPDs on its product pages. See the Vesiset overview that lists EPD links for aluminium, stainless steel and throw‑out pipes: https://www.kouruset.fi/vesiset-parvekevedenpoisto/
Product‑specific pages for the exterior UP system and the internal Plus system also reference EPDs for designers:

• Vesiset UP: https://www.kouruset.fi/vesiset-ulkopuolinen/
• Vesiset Plus: https://www.kouruset.fi/vesiset-plus-parvekevedenpoisto/
  If any PDFs are missing from those pages, add a visible “Environmental Product Declarations” block on each SKU page and a central library link in the main navigation. Small change, big visbility win.

What this means for bids and prequals

• Product‑specific EPDs remove default penalties and keep Vesiset in play when carbon accounting is mandatory.
• Family coverage means fewer holes for value‑engineering to exploit across interior, exterior and throw‑out options.
• Publishing now positions Kouruset to ride portfolio‑wide updates faster, rather than scrambling one project at a time. We see that as the smart play.

One step to keep momentum

Map the next two publication milestones to sales priorities, not just engineering order. For fast‑moving residential pipelines, that usually means refreshing any adjacent fittings and accessories that land in the same submittal folder. Dont make reviewers hunt. Tie each EPD link to model downloads and installation guidance so the whole package moves together.
