Overview

EN 14063-2:2013 is the CEN European Standard that specifies requirements for in‑situ formed loose‑fill expanded clay lightweight aggregate (LWA) when installed in buildings. It is Part 2 of the EN 14063 series and defines the specification for the installed product used in roofs, ceilings, floors and ground floors. Part 2 is intended to be used together with EN 14063-1 (the product/specification for loose‑fill before installation) and supports declarations and checks made by the installer. Note: EN 14063‑2:2013 does not set absolute performance levels for particular applications - these are established by national regulations or non‑conflicting standards.

Key topics and requirements

• Scope & exclusions: applies to loose‑fill expanded clay LWA installed on site; excludes factory‑made LWA products and insulation for building equipment/industrial installations. Acoustic performance (airborne sound insulation / absorption) is not covered.
• Installer obligations: use products compliant with EN 14063‑1, inspect building suitability, follow manufacturer instructions and Annex B installation guidelines when national rules are absent.
• Declared installed thermal resistance (R): calculated from the declared mean installed insulation thickness (d) and the declared thermal conductivity (λ) using R = d / λ. R must be declared by the installer.
• Declared installed thickness & measurements: the mean installed thickness after compaction must meet the designer’s specified thickness. Measurement protocol: at least five thickness readings per 100 m² (pin or ruler; EN 823 referenced for disputed cases).
• Compaction & density: installer must achieve specified degree of compaction; compaction is expressed as a percentage of initial thickness. Annex A gives the method to determine density and compaction in dispute cases. Typical compaction for rounded aggregates: 5–15%.
• Moisture content: measured per EN 1097‑5 when required (e.g., when in contact with timber).
• Installer’s declaration: must include product trade name/code, confirmation that installed thickness ≥ design thickness, declared R, total quantity used, installation date and related details.

Applications and users

Who uses EN 14063‑2:2013:

• Building contractors and installers of loose‑fill expanded clay insulation
• Architects and specifiers writing installation requirements
• Manufacturers (for producer/installer interface)
• Building control authorities and inspectors
• Test laboratories and consultants verifying in‑situ performance

Practical use cases:

• Thermal upgrade of roofs, lofts, floors and ground floors using in‑situ expanded clay LWA
• On‑site verification of installed thermal resistance and thickness for compliance and energy performance calculations

Related standards

• EN 14063‑1 (product specification for loose‑fill LWA)

Foreword
This document (EN 14063-2:2013) has been prepared by Technical Committee CEN/TC 88 "Thermal
insulating materials and products", the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by January 2014, and conflicting national standards shall be withdrawn at
the latest by January 2014.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This European standard consists of two parts. The first part is the harmonised part satisfying the mandate and
the CPD. It is the basis for the CE marking covering the products, which are placed on the market. The
second part, which is the non-harmonised part, covers the specification for the installed products. Both parts
need to be used for the application of the insulation products in the end-use applications covered by
EN 14063.
Part 1 of this European Standard has been prepared under a mandate given to CEN by the European
Commission and the European Free Trade Association and supports the essential requirements of EU
Directives. For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of Part 1.
Attention is drawn to the need to take into account any complementary member state rules (e.g. installation
rules) which together with this European Standard ensures the fitness for purpose of the installed product.
This European Standard is one of a series for mineral wool, expanded clay, expanded perlite, exfoliated
vermiculite, polyurethane/polyisocyanurate, cellulose, bound expanded polystyrene and expanded polystyrene
in-situ formed insulation products used in buildings, but this standard can be used in other areas where
appropriate.
The reduction in energy used and emissions produced during the installed life of insulation products exceeds
by far the energy used and emissions made during the production and disposal processes.
According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following
countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech
Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece,
Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal,
Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
