Thermal insulation products for building equipment and industrial installations - Factory made products of expanded polystyrene (EPS) - Specification

This European Standard specifies the requirements for factory made products of expanded polystyrene which are used for the thermal insulation of building equipment and industrial installations with an operating temperature range of approximately - 180 °C to + 80 °C. Modified expanded polystyrene polymers with a higher temperature resistance are also covered by this standard.
Below an operating temperature of - 50 °C, special tests regarding the suitability of the product in the intended application are advised (e.g. liquefaction of oxygen). Manufacturers’ advice should be heeded in all cases.
The products are manufactured in the form of faced or unfaced boards, rolls, lags, pipe sections or other prefabricated ware.
This standard describes product characteristics and includes procedures for testing, evaluation of conformity, marking and labelling.
Products covered by this standard are also used in prefabricated thermal insulation systems and composite panels; the performance of systems incorporating these products is not covered.
This standard does not specify the required level or class of a given property that should be achieved by a product to demonstrate fitness for purpose in a particular application. The classes and levels required for a given application can be found in regulations and invitations to tender.
Products with a declared thermal conductivity greater than 0,060 W/(m·K) at 10 °C are not covered by this standard.
This standard does not cover products for in situ insulation (for loose fill or poured insulation) or products for the insulation of the building structure.

Overview

EN 14309:2015 - "Thermal insulation products for building equipment and industrial installations - Factory made products of expanded polystyrene (EPS) - Specification" is a CEN European Standard that defines requirements and test procedures for factory‑made EPS products used for thermal insulation. It covers EPS items (faced or unfaced) in forms such as boards, rolls, pipe sections, lags and other prefabricated ware intended for building equipment and industrial installations with an approximate operating temperature range of −180 °C to +80 °C. Modified EPS with higher temperature resistance is also included. The standard sets out characteristics, testing, conformity assessment, marking and labelling - but not the required performance levels for specific projects.

Key topics and requirements

• Scope and exclusions: Applies to factory‑made EPS; excludes in‑situ loose fill/poured EPS and products for building structural insulation. Products with declared thermal conductivity > 0.060 W/(m·K) at 10 °C are excluded.
• Temperature guidance: Special suitability tests are advised below −50 °C (e.g., to address oxygen liquefaction risks); manufacturers’ instructions must be followed.
• Product properties and tests: Specifies thermal conductivity, dimensions and tolerances, dimensional stability, reaction to fire, compressive and tensile strength, water absorption, apparent density, vapour transmission and other durability characteristics.
• Test methods and sampling: Includes conditioning, sampling and standardized test procedures for performance verification.
• Conformity and factory control: Describes Product Type Determination (PTD), Factory Production Control (FPC), Assessment and Verification of Constancy of Performance (AVCP) and marking/CE labelling requirements (see Annex ZA for Construction Products Regulation links).
• Annexes: Normative annexes cover factory production control, product classification and minimum service temperature determination; informative annexes list additional properties.

Applications

EN 14309:2015 applies to EPS insulation used in:

• HVAC and building services pipework and ducts
• Refrigeration and cold chain installations (including cryogenic equipment, with caution below −50 °C)
• Process pipework and industrial installations where factory‑made EPS components are specified
• Prefabricated thermal insulation systems and composite panels (note: system performance is not covered)

Who uses this standard

• EPS manufacturers and product designers (for product specification and FPC)
• Specifiers, mechanical and building services engineers (for material selection)
• Test laboratories and conformity assessment bodies (for AVCP testing)
• Procurement teams and contracting authorities (to reference in tenders and regulations)
• Regulators ensuring compliance with CPR and CE marking

Related standards

EN 14309 is part of a CEN package for factory‑made thermal insulation products (e.g., EN 14303, EN 14304, EN 14307, EN 14308). For project suitability, check applicable national regulations, tender specifications and manufacturer guidance.
