Isover Saint‑Gobain UK enters the EPD arena

Published: January 6, 2026

Specs move fast when the paperwork is already done. Isover Saint‑Gobain UK just published its first Environmental Product Declarations for glass mineral wool, putting clear numbers on performance so project teams can compare apples to apples instead of guesswork. It is a smart, commercial move that opens more doors in bids where product‑specific EPDs are a pass‑fail filter.

What just went live

EC3 shows Isover Saint‑Gobain UK with product‑specific EPDs for Acoustic Partition Roll APR 1200 in 50 mm and 65 mm thicknesses. These sit in MasterFormat 07 21 16 Blanket Insulation and were issued by EPD International AB under EN 15804 A2. The listed LCA developer is Renuables Ltd, with Callum Hill as practitioner. Scope is single products by thickness, a clean starting point for a family rollout.

Why it matters in the market

Product‑specific EPDs remove penalty assumptions in low‑carbon projects. That keeps Isover in contention when specifiers must document embodied carbon instead of relying on conservative defaults. These are tangible signals the market was waiting for, they lower friction in tendering.

Where to find the documents

Isover has created a dedicated EPD resource page with downloads for Acoustic Partition Roll sizes. Bookmark it so sales and distributors do not hunt through folders later (Isover UK EPD Certificates). The EPD International library also lists additional Isover entries such as APR 1200 100 mm valid through 21 April 2030 (EPD International, 2025) and Cladding Roll 40 100 mm valid through 31 March 2030 (EPD International, 2025).

Quick company backdrop

Isover is Saint‑Gobain’s UK insulation brand for residential and commercial buildings. The range spans acoustic rolls, cavity wall slabs, technical pipe and duct wraps, and loft rolls used across partitions, roofs, facades, and services. An EPD foothold here brings their core portfolio into more specification sets where transparency is no longer optional.

Competitive snapshot

Closest rivals in the UK glass and stone mineral wool set include Knauf Insulation, ROCKWOOL, and Superglass. Knauf already publishes multiple glass mineral wool EPDs across formats in Europe. ROCKWOOL has stone wool blanket EPD coverage with European operators. Superglass lists at least one product EPD for blowing wool. Isover’s first entries close a visibility gap in partitions and signal more to come in slabs, loft, and technical insulation.

What this debut means for bids

  • Sales can answer the two questions that stall submittals most often. Do you have an EPD and is it product‑specific.
  • Estimators can model embodied carbon with declared values instead of generic penalties.
  • Spec writers can cite program operator, PCR, and declared unit directly in section 07 21 16 notes.

Smart next steps

Round out the family so common thicknesses and facings have coverage. Align future EPDs to the PCR choices most used by comparable products to keep comparisons fair in multi‑bid evaluations. Make the EPD hub easy to find from every product page and the sustainability menu. If the plan is to scale quickly, pick an LCA partner that takes on data collection and publishes with your preferred operator while your team focuses on operations rather than spreadsheet wrangling. That is where speed saves real money.

Final word

Isover Saint‑Gobain UK has entered the transparency arena with credible, verifiable declarations for building‑scale insulation. It is not just good enviromental housekeeping. It is a practical edge in projects that reward clarity over claims.

Where can I download Isover UK’s EPDs?

How does this change competitive dynamics?

Competitors like Knauf and ROCKWOOL already publish EPDs for mineral wool. Isover’s first wave removes a prior barrier to being written into specs that require product‑specific declarations, especially in partitions, and positions them to expand into slabs, loft, and technical insulation next.
