Window film is a polyester film generally made of PET, Polyethylene Teraphthalate, the same polymer used to manufacture water bottles, for example. Most films are applied to the interior surface of a glass window in a home, commercial building, or car. They have a scratch resistant coating on the outer surface to protect the film.
There are many types of window films. Some are clear and feature multiple layers of PET to offer protection from shattering glass; others are tinted with metals, dyes or pigments to reduce the visible light transmitted through the glass, and block heat coming through from the sun. There are even decorative window films that can replicate the look of frosted glass or etched patterns.
Window films have many benefits depending on your choice of film.
Safety films can hold shattered glass in place to offer protection from threats like:
- Burglary attempts
- Wind-born debris
- Natural disasters
- Bomb blasts
Tinted window films, also called solar control films, can do the following:
- Significantly reduce solar heat gain and temperature inside a building
- Reduce air conditioning costs
- Extend life of HVAC systems by reducing maintenance and strain on the system
- Decrease a building’s environmental emissions
- Increase occupant comfort
- Reduce glare to improve visibility inside, especially for computer and TV screens
- Provide daytime privacy
- Block up to 99% of UV radiation
- Offer significant fade protection for furniture, carpets, woodwork, and other interior furnishings
- Improve building aesthetics and accent windows
Answer: Windows with film applied are easily cleaned without damage to their appearance as long as a few common-sense guidelines are followed:
1. Use a soft clean cloth, soft paper towel, or clean synthetic sponge.
2. Use a soft cloth or squeegee for drying the window.
3. Use any normal glass cleaning solution which contains no abrasive materials.
The availability of scratch resistant coatings as a standard feature of quality films has virtually eliminated the need for extra special precautions in cleaning.
Kaedah 5 (1) dan Kaedah 5 (3),Kaedah-Kaedah Kenderaan Motor (Larangan Mengenai Jenis-Jenis Kaca Tertentu) Pindaan 2000, menetapkan cermin cermin depan hendaklah telus cahaya tidak kurang 70%, manakala cermin belakang dan tepi hendaklah telus cahaya tidak kurang dari 50%.
The use of Tinted Film on vehicle Front light penetration at least 70% & above, Side window at least 50% light penetration, Rear at least 50% light penetration and the width should not exceed 20% of the length of the windscreen.
Film provides various advantages like heat rejection, protection from harmful UV rays (upto 98%) and protection from flying splinters in the case of accidental breakage of glass; which are not achieved in tinted glass. Thus it is better than tinted glass on these parameters.
SAFETY FILMS - Consist of a single thin sheet of polyester with 4 to 7 mil or .004 to .007 inches in nominal thickness.
Safety films are available in clear, solar control reflective or architecturally tinted and Ultra-Violet (UV) radiation protection
Safety films are primarily utilized for limited shatter resistance from light load bearing affects which would normally crack, shatter or cause breakage from accidental or limited natural causes
SECURITY FILMS consist of multiple layers of polyester film laminated together with pressure sensitive acrylic adhesive.
Security films are typically made in nominal thickness of 8mil and above.
Security laminates are the single most cost effective means for the prevention of penetration and resultant injury and damage from forced entry attacks, explosive blasts and projectile entries on retrofit applications.
BUYER BEWARE. They are a lot of installers claim that the 4mil safety film can prevent the force entry attacks and the claim is not valid.
There is no way that the safety film can stop the bullet or offer any kinds of resistance to the bullet.
Security film with the thickness of at least 12mil and apply to the glass thickness of 6 inches making it possible to defeat 0.38 caliber round, 0.45 caliber jacketed hollow point bullets and 9mm jacketed hollow point bullet.
Security film with the thickness of less than 12mil might be able to offer some resistance to small caliber handgun bullet but to be safe, the 12mil is still required.
Reason 1 – decrease heat
Solar film can provide up to 70% solar energy rejection (IR is not the accurate measurement of heat rejection, instead you should focus on the Total Solar Energy Rejection to determine the quality of the film), with the reduction in solar energy, the interior of the car & building will become cooler and this will significantly reduce air conditioning usage
Reason 2 – Reduce fading
Solar film that blocks up to 99% UV rays help to protect and extend the life of automobile & building interior including seats, carpets, dashboard and wood trim
Reason 3 – Diminish Health Risks
Exposure to UV rays from sun is known to pose potential health risks for eyes and screen
Reason 4 – Cut Hazardous Glare
Glare from either sun or headlight could endanger the driving because the glare can blind your vision when on the road
The safety and security film provides the same benefits like the solar film but the security film provides additional protection against
- Accidental injury
