EN 16809-1:2019 - Overview

EN 16809-1:2019 (CEN) specifies requirements for in‑situ formed thermal insulation products made from loose‑fill and bonded expanded polystyrene (EPS) beads before installation. It covers product characteristics, test procedures, marking and labelling for EPS beads intended for filling masonry cavity walls and frame constructions. This part is the product specification (Part 2 of EN 16809 covers installed products). The standard does not set application‑specific performance levels - those are determined by regulations or complementary standards.

Key topics and technical requirements

• Scope and exclusions
  • Applies to loose‑fill and bonded EPS beads for masonry cavities and frame constructions.
  • Excludes factory‑made EPS boards, products for building equipment/industrial installations, airborne/acoustic products, and products with declared R < 0.25 m2·K/W or λ > 0.060 W/(m·K) at 10 °C.
• Thermal properties
  • Thermal resistance (R) and thermal conductivity (λ) measured per EN 12667 / EN 12939.
  • Declared values must represent at least 90 % of production with 90 % confidence (90/90). λ rounded upwards to 0.001 W/(m·K); R rounded down to 0.05 m2·K/W increments.
• Physical properties
  • Density of a sale unit (EN 1602) must meet manufacturer’s declared minimum.
  • Bead size measured per EN 933‑1 (typical bead sizes ~1–10 mm depending on injection method).
  • Settlement (loose fill) measured per Annex G; bonded beads have no settlement.
• Reaction to fire
  • Classification per EN 13501‑1 using relevant reaction‑to‑fire tests and mounting rules (EN 15715 and Annex D).
• Durability and ageing
  • Declared thermal properties and reaction‑to‑fire performance are considered durable; settlement covers long‑term loose‑fill behaviour.
• Quality & conformity
  • Procedures for product type determination, factory production control (FPC), marking, labelling and Declaration of Performance (DoP) are specified.

Applications and who uses this standard

• Target users:
  • EPS manufacturers, product developers and quality managers
  • Testing laboratories and certification bodies
  • Architects, specifiers and building contractors specifying cavity and frame insulation
  • Regulators and conformity assessment bodies
• Practical use:
  • Establish product datasheets and DoP for marketed EPS bead products
  • Define test programmes for thermal performance, density, settlement, and fire reaction
  • Ensure labelling and FPC meet European market requirements before on‑site installation

Related standards

• EN 12667, EN 12939 (thermal tests)
• EN 1602, EN 1609, EN 12086 (density, water absorption, vapour)
• EN 13501‑1, EN 13823, EN ISO 1182, EN ISO 11925‑2 (reaction to fire)
• EN 13172 (conformity), EN 15715 (mounting for fire tests)

EN 16809‑1:2019 is essential when marketing, testing or specifying in‑situ EPS bead insulation - it defines how product performance must be measured and declared prior to installation.

4.3.6 Release of dangerous substances
National regulations on dangerous substances may require verification and declaration on release, and
sometimes content, when construction products covered by this document are placed on those markets.
In the absence of European harmonized test methods, verification and declaration on release/content should
be done taking into account national provisions in the place of use.

5.3.2 Thermal resistance and thermal conductivity
Thermal conductivity shall be determined in accordance with EN 12667 and EN 12939 for thick products under
the following conditions:
— at a mean temperature of (10 ± 0,3) °C;
— after conditioning in accordance with 5.2;
— the test specimen shall be prepared according to Annex C of this document.
Thermal resistance and thermal conductivity may also be measured at mean temperatures other than 10 °C, if
the correlation of the relationship between temperature and thermal properties is documented.
Thermal resistance and thermal conductivity shall be determined directly at the measured thickness. In the
event that this is not possible, they shall be determined by measurements on other thicknesses of the product
providing that:
— the product is of similar chemical and physical characteristics and is produced on the same production
unit;
— it can be demonstrated in accordance with EN 12667 and EN 12939 for thick products that the thermal
conductivity does not vary more than 2 % over the range of thicknesses where the calculation is applied.
5.3.3 Reaction to fire
Test shall be carried out in accordance with EN 13501-1.
Rules for mounting and fixing when testing are given in Annex D and EN 15715.
6 Designation code
The manufacturer shall give a designation code for the product. The following shall be included except when
there is no requirement for a property described in 4.3:
— In situ formed EPS beads EPS
— This document number EN 16809-1
— Settlement class (only for loose-fill beads products) Si
— Water absorption WS
— Water vapour diffusion resistance factor MUi
where “i” shall be used to indicate the relevant class or level.
The designation code for a loose-fill expanded polystyrene product is illustrated by the following example:
EXAMPLE EPS EN 16809-1 – S1 – WS – MU1
7 Assessment and verification of the constancy of performance
7.1 General
The manufacturer or his authorized representative shall be responsible for the conformity of his product with
the requirements of this document. The verification of the constancy of performance shall be carried out in
accordance with EN 13172 and shall be based on product type determination (PTD) and factory production
control (FPC) by the manufacturer, including product assessment and tests on samples taken at the factory.
The compliance of the product with the requirements of this document and with the stated values (including
levels and classes) shall be demonstrated by:
— Product type determination (PTD);
— Factory production control by the manufacturer, including product assessment.
If a manufacturer decides to group his products, it shall be done in accordance with EN 13172.
7.2 Product type determination
All characteristics defined in 4.2 and those in 4.3 if declared shall be subject to product type determination
(PTD), in accordance
