Introduction
This document provides rules for the assessment and quantification of parameters describing the
environmental impact of thermal insulation products to prepare environmental product declarations.
It defines complementary product category rules (PCR) for thermal insulation products based on the core
rules for all construction products established in EN 15804:2012+A2:2019 . These rules are intended to
be used in conjunction with EN 15804:2012+A2:2019 .
These PCR apply to all CEN/TC 88 thermal insulation product standards (EN 13162 to EN 13171,
EN 14063-1, EN 14064-1, EN 14303 to EN 14309, EN 14313, EN 14314, EN 14315-1 to EN 14320-1,
EN 14933, EN 14934, prEN 15100-1, EN 15101-1, EN 15501, EN 15599-1, EN 15600-1, EN 15732,
EN 16025-1, EN 16069, prEN 16491, EN 16809-1, EN 16863, EN 16977, EN 17140) in order to minimize
intra-sectoral deviations. These PCR are also valid for thermal insulation products outside of CEN/TC 88
and for thermal insulation products involved in other CEN/TCs.
As in EN 15804:2012+A2:2019 , the results from the assessment are expressed following the modularity
principle in a form that allows aggregation (addition) to provide complete information for construction
works. These PCR do not deal with aggregation at the construction works level nor does it describe the
rules for applying the environmental parameters in a construction works assessment.
The reduction in energy used and the reduction of emissions produced during the installed life of
insulation products exceed by far the energy used and in most cases the emissions occurring during the
production, installation and disposal processes. 5.4 of this document provides the rules for declaration of
any such benefits as additional information.
NOTE The titles of the clauses in this document follow EN 15804:2012+A2:2019 to enhance readability.
1 Scope
This document provides the product category rules (PCR) for Type III environmental declarations (as in
EN 15804:2012+A2:2019 ) for factory made and in situ thermal insulation products.
Complementary to EN 15804:2012+A2:2019 , the PCR described in this document:
— specify the declared unit to be used;
— define the system boundaries for thermal insulation products;
— specify/describe the default scenarios and rules for defining scenarios for certain life cycle
information modules.
These PCR are intended to be used for cradle to gate, cradle to gate with options or cradle to grave
assessment, provided the intention is properly stated in the system boundary description.

5 General aspects
5.1 Objective of the core PCR for insulation products
The objective is as in EN 15804:2012+A2:2019 and the Scope of this document.
5.2 Types of EPD with respect to life cycle stages covered
These PCRs identify two main families of EPDs:
1) EPDs for factory made thermal insulation products;
2) EPDs for in situ thermal insulation products including installation.
To be in compliance with this document, the mandatory and voluntary product stages to be declared for
both families are described in Figure 1. This table applies as well for factory made thermal insulation
products, that have their applicable technical characteristics (e.g. thermal resistance) at the factory gate
as well as for in situ formed thermal insulation products that establish their applicable technical
characteristics after activities on site.
For an EPD type “Cradle to gate with options” the declaration of modules A4, “Transport” and A5
“Installation” of the construction process stage is optional. Also, the modules B1 to B7 covering the use
phase are optional. The declaration of the modules of the other life cycle stages is mandatory.
For an EPD type “Cradle to grave” all modules are mandatory.
For each of these EPD, mandatory and voluntary stages are described as in Figure 1.

o Optional
i Mandatory provision of scenario description and technical information

5.3 Comparability of EPD for construction products
In principle, the comparison of products on the basis of their EPD is defined by the contribution they
make to the environmental performance of the construction works. The comparison of the environmental
performance of construction products using the EPD information should meet both the required
functional and technical requirements. In some cases, construction products are not functionally
equivalent; if so, the EPDs could be still used, not to compare but to evaluate the environmental
performance and its impacts on the construction works, and shall consider the complete life cycle (all
information modules). End use applications are defined in Annex A. Cradle to grave analyses can describe
all relevant requirements for the end-use application of the product.
The main purpose of incorporating thermal insulation products is to reduce the energy consumption in
the use stage of buildings. Since the reduction of the environmental impacts due to energy savings during
the use stage is in most cases much higher than the environmental impacts of the insulation products
themselves, focus on good performance on building level during use is more important than comparing
insulation products.
5.4 Additional environmental information
Additional environmental information shall be as in EN 15804:2012+A2:2019 and Annex A of this
document.
If benefits of thermal insulation products due to energy saving during the installed life are reported in
relation to the environmental performance of a building, they shall be reported as additional information.
The environmental impacts shall be calculated using EN 15978. The benefit is the difference between the
impacts of at least two thermal insulation performances for the same building considered over the whole
life cycle. The scenarios shall be fully described in the EPD and sufficient information given to the verifier
to verify this.
5.5 Ownership, responsibility and liability for the EPD
The ownership, responsibility and liability for the EPD shall be as in EN 15804:2012+A2:2019
Communication formats.
The communication format of the EPD shall be in accordance with EN 15942.

6.2 Life cycle stages and their information modules to be included

the thermal resistance (R-value) is not relevant for a specific building equipment or a specific civil
engineer
