FprEN 17140
(Main)This document defines characteristics for factory made Vacuum Insulation Panels (VIP), with or without protective layer, which are used for the thermal insulation of buildings. This standard describes the product properties and contains test methods and rules for assessment and verification of constancy of performance (AVCP), identification and labelling. The determination of VIP properties influencing the service life time and VIP performance is content of this standard as well. The standard provides a test method to determine the ageing of the product including the influence of the linear thermal bridges at the edges.
This standard is applicable for all types of VIP independent of the core material or type of envelope. It is also applicable for VIP using desiccants but not getters, due to a lack of experience with ageing of these panels.
This 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 can be found in regulations or non-conflicting standards.
Products with a declared thermal resistance RD lower than 0,5 m2 K/W or a declared thermal conductivity λD according to Annex C of this Standard greater than 0,015 W/(m⋅K) are not covered by this standard.
This standard does not cover products intended to be used for the insulation of building equipment and industrial installations.

This standard defines requirements for factory made Vacuum Insulation Panels (VIP), which are used
for the thermal insulation of buildings. This standard describes the product properties and contains test
methods and rules for conformity evaluations, identification and labelling. The determination of VIP
properties influencing the service life time and VIP performance is content of this standard as well. The
standard provides a test method to determine the ageing of the product including the influence of the
linear thermal bridges at the edges.This standard is applicable for all types of VIP independent of the core material or type of envelope. It is
also applicable for VIP using desiccants but not getters, due to a lack of experience with ageing of these
panels.This 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
can be found in regulations or non-conflicting standards.Products with a declared thermal resistance R lower than 0,5 m K/W or a declared thermal
conductivity λ according to Annex C of this Standard greater than 0,015 W/(m⋅K) are not covered by
this standard.This standard does not cover products intended to be used for the insulation of building equipment and
industrial installations.2 Normative references
