Overview

The European Standard prEN 15752-1 titled Glass in building - Adhesive backed polymeric film - Part 1: Definitions and descriptions establishes clear definitions and performance characteristics for adhesive backed polymeric films designed for application on building glass. Developed by CEN Technical Committee CEN/TC 129, this standard provides a crucial framework for manufacturers, architects, and builders by defining material properties, usage limitations, and testing protocols for these specialized films.

This standard excludes adhesive backed polymeric films made from polyvinylchloride (PVC) and highlights that additional specifications may apply for films used within composite glass assemblies such as laminated or insulating glass units. Its focus is on ensuring mechanical and thermal stability of these films without degradation.

Key Topics

• Adhesive Backed Polymeric Film Definition
  Defined as one or more layers of polymer film with an adhesive on one side, potentially including elements like UV absorbers, metal or metal oxide layers, and scratch-resistant surfaces.

• Film Types
  The standard outlines various categories of adhesive films designed for glass modification, including:

  • Clear films - for basic surface protection or appearance.
  • Solar control films - reduce solar heat gain and glare.
  • Safety and security films - improve impact resistance and prevent shattering.
  • Decorative films - alter aesthetic appearance.
  • Anti-graffiti films - protect glass surfaces from vandalism.
  • UV reducing films - block harmful ultraviolet radiation.
  • Low emissivity (Low-E) films - enhance thermal insulation.
  • Privacy films - restrict visibility.
  • RFI/EMF shielding films - attenuate electromagnetic frequency interference.

• Performance Characteristics
  Includes detailed parameters for thickness tolerances, optical properties, adhesion strength, abrasion resistance, durability under accelerated weathering, and haze measurement techniques.

• Testing Methods
  The document specifies evaluation procedures such as:

  • Accelerated weathering tests to simulate long-term environmental exposure.
  • Taber abrasion testing to assess scratch and wear resistance.
  • Solar optical measurements to gauge glare reduction and solar heat control.
  • Adhesion and tensile strength tests for safety/security films.

Applications

Adhesive backed polymeric films, as defined by prEN 15752-1, serve numerous practical applications in modern building design and renovation:

• Energy Efficiency
  Solar control and Low-E films help reduce energy consumption by improving glazing solar heat gain and thermal insulation.

• Safety Enhancement
  Safety and security films improve occupant protection by reinforcing glass integrity in case of impact, blast, or forced attack.

• Aesthetic and Privacy Control
  Decorative and privacy films provide versatile options for visual appearance and occupant seclusion without permanent architectural changes.

• Surface Protection
  Anti-graffiti films preserve glass surfaces in public or high-risk environments, reducing cleaning and maintenance costs.

• Electromagnetic Interference Shielding
  RFI/EMF films protect sensitive electronic environments by limiting electromagnetic penetration through glass panes.

These films can be applied in new constructions or retrofit projects on various building types such as commercial offices, residential buildings, schools, hospitals, and public facilities.

Related Standards

prEN 15752-1 aligns and references several important glass-related European and international standards, ensuring comprehensive quality and safety compliance:

• EN 356: Resistance to manual attack on glass.
• EN 410: Methods for determining luminous and solar characteristics of glazing.
• EN 673: Calculation of thermal transmittance (U-value) in glazing.
• EN 12600: Pendulum impact testing for flat glass.
• EN 50147-1: Measurements for shield attenuation in anechoic chambers.
• EN 1063 and EN 13541: Standards for bullet resistance and blast resilience of glass respectively.

These standards collectively support the integration of adhesive backed polymeric films into glazing products to achieve enhanced performance in safety, energy efficiency, and durability.

adhesive layer. These are removed prior to film installation.
A typical construction of an adhesive backed polymeric film is shown in Figure 1.
