An EPD, or Environmental Product Declaration, is a document that transparently describes the environmental impacts of a product over its life cycle. TAVINOX has EPDs for two product groups — other products, such as the GROOVE system or tools, do not have an EPD:
- • TAVINOX – Stainless steel welded tubes — TAVINOX welded stainless steel tubes (Ø 15–108 mm)
- • TAVINOX PRESS – Stainless steel press fittings — the press fitting range
The EPD was verified by Technický a zkušební ústav stavební Praha, s. p. (the Czech technical and test institute for construction), certification body no. 3015, accredited by the Czech Accreditation Institute.
What an EPD is and why it matters
An EPD is a type III environmental product declaration. It documents the environmental impacts of a product transparently, under uniform rules and a uniform methodology. For construction products, EPDs are becoming increasingly important wherever the following are addressed:
- • environmental assessment of buildings,
- • sustainability of construction works,
- • ESG requirements,
- • public and developer tenders,
- • technical documentation with documented environmental data,
- • whole-building assessment to EN 15978 during design preparation.
For designers and investors, an EPD matters above all because it provides verified data. It is not a marketing claim by the manufacturer but a document based on a life cycle assessment of the product and verified by an independent third party.
Verified EPDs for two TAVINOX product groups
The verification covers TAVINOX welded tubes and TAVINOX PRESS press fittings.
| Product group | EPD registration number |
|---|---|
| TAVINOX – Stainless steel welded tubes | 3015-EPD-030070030 |
| TAVINOX PRESS – Stainless steel press fittings | 3015-EPD-030070031 |
The verification of the environmental product declaration was issued on 16 June 2026 and is valid until 16 June 2031. The separate EPDs for the two product groups carry a version date of 17 June 2026 and are valid until 17 June 2031.
The rules the EPD was prepared under
The EPD was prepared and verified in accordance with recognised standards for environmental declarations and life cycle assessment. The main documents used are:
- • ČSN ISO 14025 – Environmental labels and declarations, type III environmental declarations,
- • ČSN EN 15804 + A2 – Sustainability of construction works, environmental product declarations,
- • ČSN EN ISO 14040 – Life cycle assessment, principles and framework,
- • ČSN EN ISO 14044 – Life cycle assessment, requirements and guidelines,
- • the product category rules PCR ČSN EN 15804+A2:2020,
- • the rules of the National Environmental Labelling Programme.
The EPD is registered in the NPEZ – National Environmental Labelling Programme, whose programme operator is the Ministry of the Environment of the Czech Republic.
What the EPD covers
The EPD describes the environmental impacts of the product across its life cycle. For TAVINOX products, the stages included are mainly:
- • A1–A3 – raw materials, manufacturing and related processes,
- • A4 – transport to site,
- • A5 – installation and handling of packaging (declared for the fittings only),
- • C1–C4 – end of life: dismantling, sorting, recycling or disposal,
- • D – benefits and loads beyond the system boundary, in particular those relating to recycling.
Stages B1–B7 are excluded for these products, because tubes and fittings are passive parts of the system and, in normal operation, require no further inputs or maintenance that would be included in the EPD calculation.
The EPD for TAVINOX welded tubes
The EPD for TAVINOX – Stainless steel welded tubes covers stainless steel welded tubes. The declared scope includes tubes:
- • in diameters from 15 to 108 mm,
- • with a wall thickness of 1.0 to 2.0 mm,
- • in a standard length of 6,000 mm.
The declared unit is 1 tonne of finished stainless steel tube. TAVINOX tubes are made of stainless steel and are used for MEP pipework and other applications where material resistance, a long service life and system stability matter. The EPD also states the recycled input content of the stainless steel — for TAVINOX tubes a 73% share of post-consumer recycled material is declared.
The EPD for TAVINOX PRESS press fittings
The EPD for TAVINOX PRESS – Stainless steel press fittings covers stainless steel press fittings made of AISI 316L corrosion-resistant steel. The declared scope includes press fittings in sizes 15, 18, 22, 28, 35, 42, 54, 76.1, 88.9 and 108 mm.
The declared unit is 1 kg of finished stainless steel press fitting. TAVINOX PRESS fittings are intended for use in pipework for:
- • drinking water,
- • heating,
- • cooling,
- • compressed air,
- • industrial applications.
For TAVINOX PRESS fittings, the EPD states an 80% share of post-consumer recycled material in the stainless steel.
Why the EPD matters to designers and investors
With MEP pipework, the long-standing focus has been on the material, the pressure rating, certification, service life and the installation method. Alongside these, the importance of environmental data keeps growing.
An EPD helps designers and investors work with a product on the basis of verified figures. That matters above all on projects that address sustainability, environmental assessment of the building or a transparent choice of materials. For designers, an EPD is a way to add more precise information about the products used to the technical documentation; for investors, a verified EPD is a further argument when choosing a material solution.
Stainless steel: long service life and recycling at end of life
TAVINOX builds on stainless steel as a material for MEP pipework with a long service life. Stainless steel is corrosion resistant, hygienically stable and suitable for a wide range of building services applications.
Stainless steel is a fully recyclable material. At end of life the EPD calculation assumes that 85% of the steel from fittings and 87.9% of the steel from tubes is recycled; this is a modelling assumption, not a measured figure. That matters above all on construction projects where not only the purchase price and technical function are tracked, but also the impact of the chosen material over its whole life cycle.
What it means in practice
The verified EPDs for TAVINOX welded tubes and TAVINOX PRESS press fittings have practical uses across the whole supply chain.
For designers
Designers gain a verified basis for specifying stainless steel tubes and press fittings in the technical documentation. The EPD can be used in particular on projects that address the environmental parameters of products, the sustainability of the building or a whole-building assessment to EN 15978. Only EPDs prepared under the same EN 15804 rules can be compared directly.
For installation companies
Installation companies can attach the verified EPDs for the press fittings and tubes to their quotation, alongside the technical certificates. The investor, the designer and site supervision then have the environmental data of the products used documented.
For investors
The investor gains a more transparent basis for decision-making. An EPD documents the environmental parameters of the product with verified figures that can be used when choosing materials for MEP pipework.
For wholesalers
Wholesalers gain a further technical document for talking to customers. On projects that require documented environmental parameters of products, the EPD is a document that can be passed on directly.
