Differences Between the Safety & Security Window Films

Window films are those thin laminated films which are installed to the interior glass of automobiles also to the interior and exterior glass of the home and buildings. These sheets are made from the Polyethylene Terephthalate, also known as the PET. PET is an especial element of the polyester family which is greatly used for its many benefits like clarity, dimensional stability, embedded treatments and tensile strength. Depending on the manufacturing materials, substrate type and technical functions these films can be of different types. Safety and security window film are such variation of the window films which is mainly used to guard the window glasses against any unexpected incident. Here we will discuss these films and their differences.

 

Safety Window Films

Safety window films or commonly known as the safety coating are manufactured from the PET or Polyethylene Terephthalate. These films are available in both clear and tinted sheets. It prevents the glasses from breaking into dangerous shards after breaking. The films are available in different variety based on its thickness. If installed properly, they can’t be identified on the glasses fro their clarity. These sheets can be installed to the glass after manufacturing or installation with the help of special adhesives. During any unexpected situation like earthquakes, burglary, windstorms or accident hazards it protects the glasses from shuttering.

 

Apart from this, the safety window films can also increase fire safety by holding them back for a longer time.They also provide protection from the harmful solar rays and prevent heat from entering the house by absorbing it. These sheets can be used in automobiles, homes, buildings as well as on the glass tables or shelves.

 

Security Window Films

Though both safety window film and security window films are manufactured from polyesters, the security window films are more durable and stronger than the previous one. This window film is mainly used in the higher threat environment where high-security protection is needed. The security films are made laminating one or more layers of polyesters together using adhesives. The layers of these sheets determine the thickness of the window films. The thickness may vary from 4 mils to 14 mils.

Depending on the desired characteristics of the films the adhesives also changes. The films come in a number of packages. Among these the most common packages have the width of 36”, 48”, 60” and 72” when the length varies between 50 and 100 feet. It is the thickness of the film that mainly determines how strong the film will be. When the thinner films are mostly used in the lower threat environment, the thicker one is appropriate for the higher threatening places.

 

Comparison of Safety and Security Window Films

Both these window films are made to protect glasses from shattering. But they have some differences. These are:

 

  1. The safety window films can handle accidental breakage or smaller impact situations when the security films work in superior glass hazards like bomb blasts, earthquakes, hurricanes etc.

 

  1. Safety films are mostly used in residential areas when the security films are perfect for government buildings and at high-risk communities.

 

  1. Safety films are available in a number of varieties like clear films, solar control shades to block heats, glare etc. But the Security films are only found in clear films.
