EN 14318-2:2013 PDF

Overview

EN 14318-2:2013 - “Thermal insulating products for buildings - In-situ formed dispensed rigid polyurethane (PUR) and polyisocyanurate (PIR) foam products - Part 2” is the CEN specification for the installed insulation product used in cavity walls. It complements EN 14318-1 (the system specification before installation) and, together with Part 1, links product characteristics to the essential requirements of the EU Construction Products Directive. This Part 2 standard covers installation checks, measurements and the installer’s declarations needed to document compliance for in-situ dispensed PUR/PIR cavity wall insulation.

Key topics and requirements

• Scope: Applies to in-situ dispensed rigid PUR and PIR foams installed into building cavity walls. It does not cover factory-made boards or insulation for building equipment/industrial installations.
• System compliance: Installers must use a foam system that complies with EN 14318-1.
• Suitability check: Installer must inspect the building (see Annex B) and verify the cavity and site are suitable prior to application.
• Installed thickness (d): The declared installed insulation thickness - the average cavity width - is determined according to the procedure in Annex A (measurement through injection/drill holes). The installed thickness must not be less than the client’s or manufacturer’s minimum.
• Declared aged thermal resistance (RD): RD (time-average thermal resistance over 25 years) is declared using the manufacturer’s performance chart and procedures from EN 14318-1; corrections for moisture/temperature follow EN ISO 10456 where applicable.
• On-site quality checks: Installer carries out manufacturer-defined on-site foam quality checks and generates test samples per EN 14318-1 (and local rules). Annex C addresses water vapour passage control in insulated cavities.
• Installer’s declaration: Mandatory information to the customer includes installation date, declared installed thickness, declared RD, product trade name/designation, and EC certificate of conformity.

Practical applications

• Use for documenting, verifying and certifying cavity wall insulation projects using in-situ dispensed PUR/PIR foams.
• Useful for builders, insulation contractors, energy retrofit specialists, building inspectors and specifiers who need to ensure installed performance and regulatory compliance.
• Supports energy-efficiency retrofits and new-build cavity insulation where in-situ rigid foam is specified.

Who should use this standard

• Insulation installers and contractors (installation procedures, measurements, declarations)
• Product manufacturers (to link Part 1 product information with installed product requirements)
• Building certifiers, architects and regulators (to assess fitness for purpose and conformity)
• Facility managers and homeowners (for informed procurement and compliance documentation)
