(Main)Thermal insulation products of buildings - In-situ formed products from loose-fill expanded polystyrene (EPS) beads and bonded expanded polystyrene beads - Part 2: Specification for the bonded and loose-fill products after installation
General Information
- Abstract
This European Standard specifies the requirements for expanded polystyrene (EPS) beads and the adhesive, which are after installation used for the thermal insulation of buildings. The EPS beads and the adhesive are mixed and processed on site.
This standard does not specify the required level of a given property to be achieved by a product to demonstrate fitness for purpose in a particular application. The levels required for a given application are to be found in regulations or non-conflicting standards.
This standard does not cover factory made insulation products in the form of prefabricated shapes or boards made of bonded EPS beads.
Products with a declared thermal resistance lower than 0,25 (m² x K)/W or a declared thermal conductivity at 10 °C greater than 0,1 W/(m x K) are not covered by this standard.

Overview
EN 16809-2:2017 is a CEN European Standard that specifies the requirements for in‑situ formed thermal insulation made from loose‑fill and bonded expanded polystyrene (EPS) beads after installation. It applies to EPS beads and any site‑applied adhesive used to insulate masonry cavity walls and frame constructions. The standard focuses on post‑installation verification (installed thickness, volume, thermal resistance) and the checks an installer must perform and declare. It does not cover factory‑made EPS boards, mats or batts and excludes products outside specified declared thermal resistance/conductivity limits (see the published standard for the exact threshold values).
Key topics and requirements
- Scope and exclusions: In‑situ loose‑fill and bonded EPS beads for building insulation in cavity walls and frame constructions; factory‑made prefabricated EPS products are excluded.
- Post‑installation assessment: Requirements for measuring and calculating the installed thermal resistance (R), using the declared thermal conductivity (D) and installed thickness (d). The standard provides rounding rules for declared R.
- Installation checks:
- Average cavity width measurement (Annex A) using a minimum number of inspection holes.
- Machine output and flow controls for bead and adhesive dosing (Annex B).
- Installed volume verification by comparing material supplied with calculated cavity volume; endoscope inspection method for disputes (Annex C).
- Installer responsibilities: Inspect building suitability, follow manufacturer and national rules, perform in‑situ checks and complete an installer’s declaration that records product ID, EC certificate (if any), installed thermal resistance, installed thickness/area/volume, site and date.
- Normative procedures: Detailed test/check methods and forms are provided in normative annexes (A–D) covering measurement procedures, flow checks, and suitability/installation declarations.
Applications and users
- Who uses it: Insulation installers, site supervisors, manufacturers of in‑situ EPS systems, specifiers, building control authorities and inspectors, conformity assessors, and quality auditors.
- Practical applications:
- Verifying that cavity wall and timber/metal frame insulation installations meet declared performance.
- Ensuring correct machine settings and adhesive dosing for bonded systems.
- Producing compliant installer declarations for building owners and regulatory compliance.
- Supporting quality control, dispute resolution (endoscope checks), and conformity procedures tied to Regulation (EU) 305/2011.
