Overview

EN 17101:2018 (CEN) defines identification methods and laboratory test methods for moisture‑curing one‑component polyurethane (1C‑PU) adhesive foams used as adhesive for External Thermal Insulation Composite Systems (ETICS). The standard is limited to 1C‑PU foams dispensed from pressurised containers for adhesive use; other foam types are excluded. EN 17101:2018 supports consistent performance evaluation of adhesive foams used in façade insulation systems.

Key topics and requirements

• Scope and definitions: Clear definition of PU adhesive foam, foam density, tack free time, cutting time, post application expansion behaviour, cohesion and shear strength.
• General test rules:
  • Canisters from the same batch shall be used.
  • Conditioning of canisters and specimens at (23 ± 2) °C and (50 ± 5)% r.h. for at least 24 hours.
  • Canisters shaken vigorously prior to use and first (50 ± 5) g discarded.
• Measured characteristics and test methods:
  • Foam density: five cylindrical strings (20–30 mm diameter, trimmed to 100–150 mm) measured by water displacement and mass - mean of five measurements.
  • Tack‑free time: time until a dispensed string no longer adheres to a polyethylene rod - mean of three measurements.
  • Cutting time: time until foam can be cleanly cut without damaging the structure.
  • Post application expansion behaviour: dimensional increase between substrate and insulation board during curing (specified specimen dimensions and spacers).
  • Cohesion strength and shear strength: specimen geometries, conditioning and number of measurements specified (see standard for details).
• Reporting: Test report requirements and calculation methods (formulas and rounding rules).

Practical applications

• Product development and R&D for 1C‑PU adhesive foams used in ETICS.
• Quality control and batch verification in manufacturing.
• Independent laboratory testing to verify supplier claims and performance.
• Technical specification and procurement when selecting adhesive foams for façade insulation systems.
• Comparative performance assessment for façade designers and installers.

Who should use this standard

• Foam manufacturers and formulation engineers
• Third‑party testing laboratories and quality assurance teams
• Façade system designers, specifiers and installers involved with ETICS
• Technical consultants and regulatory bodies assessing product conformity

• EN ISO 9229 (Thermal insulation - Vocabulary)
