General Information
- Abstract
This European Standard specifies requirements for in-situ formed dispensed polyurethane foam (PUR) and polyisocyanurate (PIR) foam products when installed into cavity walls.
This Part 2 of this European Standard is a specification for the installed insulation product.
This Part 2 of this European Standard describes, when taken together with Part 1 of EN 14318, the product characteristics linked to the essential requirements of the EU Construction Products Directive. It also specifies the checks and tests to be used for the declarations made by the installer of the product.
This European Standard does not specify the required levels of all properties to be achieved by a product to demonstrate fitness for purpose in a particular application. The required levels are to be found in regulations or non-conflicting standards.
This European Standard does not cover factory made rigid polyurethane (PUR) or polyisocyanurate (PIR) foam products or in-situ products intended to be used for the insulation of building equipment and industrial installations.
NOTE Foam products are either called flexible or rigid. The flexible products are used in upholstery and mattresses and are characterised by their ability to deflect, support and recover to their original thickness continually during their in-use phase. Those that are not flexible are termed rigid and do not possess these flexible characteristics. They are mostly used for thermal insulation purposes and vary widely in their compression strength values. Once the cell structure is crushed in a rigid foam, it does not recover its thickness fully. Some of these rigid foams are very low in density with very low compression strengths and are sometimes described “commercially” as “soft foams” or “semi-rigid” foams. This note has been included to clarify that all foams with such descriptions are covered by this standard’s used of the term rigid foam.

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)
