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,
the latest edition of the publication referred to applies.

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.
