ISO 16478:2023

Thermal insulation products — Vacuum insulation panels (VIPs) — Specification

This document: — defines requirements for vacuum insulation panels (VIPs) with silica or glass fibre core, which are used for thermal insulation of buildings; — outlines required product properties, their performance, test methods and rules for conformity evaluations, identification and labelling; — provides a test method to determine ageing factors and the influence of the linear thermal bridges at the edges. This document is applicable to all types of silica and glass fibre core VIPs, independent of the type of envelope. In the case of a glass fibre core VIP, it is only applicable to VIPs with desiccants whose service life is ≥ 25 years. This document is not applicable to: — any specific installation and application requirements; — products intended to be used for the insulation of building equipment and industrial installations.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
