CEN/TC 88/WG 21 - Reflective insulation products

This document is applicable to factory-made reflective insulation (RI) products intended for use as thermal and acoustic insulation of buildings. The products are manufactured in the form of rolls or boards. They are made from low emissive film(s) and infrared semi-transparent material layer(s) or air cavities.
This document describes the methods and criteria for assessing the performance of factory-made reflective insulation products in relation to essential product characteristics and includes the procedures for assessment and verification of the constancy of performance.
Reflective insulation products require specific setup instruction(s) depending on their level of compressibility.
This document does not specify the required level of a given property to be achieved by a product to demonstrate fitness for purpose in a particular application. The levels required for a given application can be found in regulations or non-conflicting standards.
This document does not cover:
-   products intended to be used for the insulation of building equipment and industrial installations;
-   products made of mineral wool, polystyrene or polyurethane foams (not inclusive) faced with aluminium or metalized foil on one or both external surfaces (which are already covered by a corresponding harmonized European product standard);
-   membranes used as vapour control layer (VCL) or vapour-permeable roof or wall underlay (which are already covered by a specific harmonized European product standard).

This European Standard specifies the requirements for factory made reflective insulation products, which are used for the thermal insulation of buildings. The products are manufactured in the form of rolls, boards or sheets and are used in conjunction with an air space or spaces and in non load-bearing applications.
It applies to thermal insulation products that derive a proportion of their claimed thermal properties from the presence of one or more reflective or low emissivity surfaces together with any associated airspace(s).
This European Standard describes product characteristics and includes procedures for testing, evaluation of conformity, marking and labelling.
This European Standard does not specify the required level of a given property to be achieved by a product to demonstrate fitness for purpose in a particular application. The levels required for a given application are to be found in regulations or non-conflicting standards.
This European Standard covers the use of products for heat retention in buildings (cold or temperate climate) and an informative annex provides for the provision of further information on the product performance for applications with downwards heat flow.
