Glass in building - Adhesive backed polymeric film - Part 1: Definitions and descriptions

This European Standard defines adhesive backed polymeric film and the performance characteristics of adhesive backed polymeric film for use, on glass, in buildings. This standard does not apply to adhesive backed polymeric films manufactured from polyvinylchloride (PVC). Other requirements, not specified in this standard, may apply to adhesive backed polymeric film that is incorporated into assemblies, e.g. laminated glass or insulating glass units. The additional requirements are specified in the appropriate product standard. Adhesive backed polymeric film, in this case, does not lose its mechanical or thermal characteristics.

Introduction

Adhesive backed polymeric film is designed to be applied to glass to modify the properties and performance of

the glass.

There are a number of different types of films that are manufactured to modify specific properties of glass:

solar energy transmittance, visible light transmittance, emissivity, Ultra Violet transmittance, privacy,

appearance, impact behaviour, electromagnetic frequency (emf) attenuation, and surface protection.

1 Scope

This European Standard defines adhesive backed polymeric film and the performance characteristics of

adhesive backed polymeric film for use, on glass, in buildings.

This standard does not apply to adhesive backed polymeric films manufactured from polyvinylchloride (PVC).

Other requirements, not specified in this standard, may apply to adhesive backed polymeric film that is

incorporated into assemblies, e.g. laminated glass or insulating glass units. The additional requirements are

specified in the appropriate product standard. Adhesive backed polymeric film, in this case, does not lose its

mechanical or thermal characteristics.
2 Normative references

This European Standard incorporates by dated or undated reference, provisions from other publications.

These normative references are cited at the appropriate places in the text and the publications are listed

hereafter. For dated references, subsequent amendments to be revisions of any of these publications apply

to this European Standard only when incorporated in it by amendment or revision. For undated references,

4 Adhesive backed polymeric films
4.1 General

Adhesive backed polymeric film products are made from one or more polymeric film layers.

The adhesive on the external surface of adhesive backed polymeric film products is either a dry water

activated adhesive or a cross-linked acrylic pressure sensitive adhesive. There are instances where a

water-based installation solution is required to facilitate the adhesion to the glass pane. The adhesive

system can be specifically designed for a performance characteristic.

A release liner or a water soluble non-sticky (detackifying) coating or both may be used to protect the

adhesive layer. These are removed prior to film installation.

A typical construction of an adhesive backed polymeric film is shown in Figure 1.

NOTE 1 The main polymeric material is bi-axially orientated polyethylene terephthalate film.

NOTE 2 Adhesive backed polymeric film manufacturers provide correct installation recommendations.
