Classes and Types of pdlc electro chromic Film Safety Glazing2021-09-08
What is the most important thing for any person? Of course, it is your own safety and the safety of family and friends. Therefore, it is now very important to install protective pdlc electro chromic film, where there is even the slightest risk of explosions, vandalism or illegal entry.
In a word, almost everywhere:
- offices of large companies
- gas stations
- restaurants, as well as private houses or apartments need protection
It is also very important to use impact-resistant films in regions prone to earthquakes or other natural disasters. Hence, where there is a threat of terrorist attacks.
Protective films are divided depending on the purpose:
The advantages of this pdlc electro chromic film have many functions. They provide the creation of explosion-proof and impact-resistant glazing. Such films absorb a significant part of the shock wave. And therefore, they are able to withstand significant mechanical loads. And even if a crack appears on the glass, it remains in the frame and fragments remain on the film.
This protective film consists of several layers of glue and polyester with a thickness of 112-380 microns. It is applied to the window surface from inside the room. And the glass, as a result of a huge mechanical load, nevertheless flies out of the frame. The glass remains on the pdlc electro chromic film, so the fragments do not fall apart.
Impact resistant pdlc electro chromic
Shock-resistant films differ in technical characteristics, on the basis of which they are divided by protection classes into A1, A2 and A3.
Impact-resistant glass is subject to testing on special equipment. This acts on the test specimen with arbitrary impacts of a falling ball of various masses. Impact-resistant glass is used in buildings where there is no need to install safety glass or other mechanical means of protection.
Protective pdlc electro chromic film is used to ensure the safety of people, as well as inventory. It is usually installed in windows and shop windows to prevent illegal entry into the premises. Security glazing will be able to detain the thief at the crime scene. This gives the security services time to respond to the alarm signal, thereby preventing crime.
Where pdlc electro chromic film can be installed?
When installing protective glasses of any class, grilles, shutters, blinds and other security elements are easy to omit. Many govt institutions approve the use of this film. The pdlc electro chromic film is installed at the following objects:
- In premises that do not contain significant material values
- It can be used for internal security system: shops, bars, restaurants, offices etc.
- Impact-resistant films of classes А 2, А 3 (Р4А, Р5А)
- In premises that contain significant material, historical and cultural values
- It can be used under internal or centralized protection;
- Furthermore, in bank rooms, buildings of authorities and administration
- They are installed in: sales rooms of weapons and jewelry stores, as well as in pharmacies
- These films are used in private houses and apartments to provide additional security.
What is the use of mirror films?
Mirror films protect our living spaces and various offices from the sun. The low cost of such a film allows it to be used on large glazing areas as pdlc electro chromic film. Also, these films ensure the confidentiality of indoor spaces, and this effect remains even with the same lighting from inside and outside the room.
Such glass protects well from ultraviolet radiation, reduces glare on computer monitors and TVs, which increases the productivity of office employees.
What is matte film?
The next type of such coatings are matte films, they have high (up to 68%) light transmittance, exclude the visibility of the room from the outside. They are widely used for covering glass of entrance doors, offices, and partitions. Tinting films also perfectly protect the room from overheating in the summer, and also save up to 30% of heat in the cold season.
Also, pdlc electro chromic film is produced, which are relevant in our time for protection against man-made electromagnetic fields. This type of glass coating is especially loved by interior designers and architects – they make it possible to radically change the appearance of buildings and premises.
When sunscreen films are used?
On hot summer days, special sunscreen films are especially useful – this type of coverage reflects most of the incoming sun rays – up to 75%. The application of such a film increases the comfort in the room, reduces the amount of glare on monitors and protects furniture and interior from burnout.
What is the use of decorative films?
Decorative films – this type of coating is specially used to change the design and transparency of the glazed coating. The use of decorative films to the greatest extent changes the color gamut of both reflected glass and light transmitted through the glass.
With the help of such a pdlc electro chromic film, you can change the color of the glass in the doors and windows at will. The effect achieved with such changes is often used to create an unusual look for familiar office spaces.
Do I need to install the film “under the glazing bead”?
When installing protective films on the glass of existing light openings in a building, it is often impossible to remove the glass fastening elements in the frame. In this case, the films are installed with a gap between the edge of the film and the glazing bead along the entire perimeter of 1-2 mm. This gap is necessary for the release of moisture remaining between the film and the glass.
What is the effect of a gap?
The presence of a gap does not in any way affect the strength characteristics of the “pdlc electro chromic film -glass” system. The fact is that the glass fixed around the entire perimeter cracks upon impact with the formation of dagger-like fragments, the tops of which are at the point of impact; the bases are formed by the ends of the glass.
