EN 14318-1:2013 PDF

Overview

EN 14318-1:2013 - Thermal insulating products for buildings - Part 1 - is the European specification for in‑situ formed dispensed rigid polyurethane (PUR) and polyisocyanurate (PIR) foam systems before installation. The standard defines product characteristics, test procedures, marking and labelling requirements, and rules for evaluation of conformity for foam dispensing systems used to insulate cavity walls. It is the harmonised (pre‑installation) part of the EN 14318 series and supports CE marking under the EU Construction Products Directive.

Key topics and technical requirements

This standard covers the specification and conformity assessment of dispensed rigid PUR/PIR foam systems and includes, among others:

• Scope and definitions clarifying rigid vs flexible foam and exclusions (factory-made products and insulation for building equipment/industrial installations).
• Product requirements for dispensed systems used in cavity wall insulation.
• Testing methods and procedures for sampling, specimen preparation, conditioning and specific tests (e.g., thermal conductivity, thermal resistance, substrate adhesion, reaction to fire).
• Aged performance: procedures to determine declared aged thermal conductivity and thermal resistance (accelerated aging and fixed increment procedures).
• Reaction to fire testing and guidance for testing in standardised assemblies and end‑use simulations.
• Evaluation of conformity including Initial Type Testing (ITT) and Factory Production Control (FPC).
• Marking, labelling and technical information obligations for manufacturers (including Annex ZA provisions related to CE marking and attestation of conformity).
• Annexes providing normative test methods and informative examples (e.g., determination of reaction profile, free‑rise density, and performance chart instructions).

Practical applications and who uses this standard

EN 14318-1:2013 is used by:

• Manufacturers of in‑situ dispensed PUR/PIR foam systems to prepare technical datasheets, demonstrate conformity, and obtain CE marking.
• Test laboratories and QA teams implementing the specified test methods for thermal performance, adhesion and fire reaction.
• Specifiers, architects and engineers evaluating products for cavity wall insulation projects and comparing declared thermal properties.
• Regulatory bodies and certification bodies assessing compliance with EU Construction Products Directive requirements.
• Installers and contractors who need to understand pre‑installation product characteristics, marking, and performance claims.

Practical uses include product development, compliance documentation, tender specifications, and producing thermal resistance performance charts for design validation.
