Window Film Checklist
What is the primary reason for having window film installed onto your windows? Typically, there are three reasons why someone chooses to have window film installed. Fade protection, glare reduction or heat rejection; there are quite a few film choices dependent on those reasons.
If glare reduction is the primary choice, it would be vital that the film reduces visible light passing through the film. Our V14 Ultima or R20 Silver would be ideal for reducing the glare; they both have a reflective nature from the exterior, while the V14 Ultima has a much lower interior reflection than the R20 Silver window film. The primary benefit of a lower interior reflection would be that you would not have a mirrored effect when looking outward.
If heat rejection is the primary issue, then it is essential to review the level of heat rejection required.
The most reflective window film, either the V14 or R20 window film, would be ideal if there is no concern about significantly reducing the light or having a reflective appearance from the exterior.
If there are concerns about dramatically reducing the light or having a highly reflective film, then the V28 Luminance is an excellent choice. The exterior reflective nature will help reflect the sun’s heat, while the less reflective appearance from the interior allows for excellent visibility even during overcast days.
If the need to increase the efficiency of your air conditioner is the primary concern, then the V38, V51 or Ceramic 40 are the best options. The V38 does have a slight reflective nature from the exterior, while the V51 and Ceramic 40 do not. The V51 and Ceramic 40 have a reflection rate of 8-9%, similar to actual glass.
When fade protection is the primary concern with no concern for heat or glare reduction, the best options are the V48, V51 and the Ceramic 60. There are slight differences in the amount of light that each film allows, however, they look very similar when installed onto the window.
Window film costs can range from $5.00 square foot upwards of $17.00 square foot, not including mobilization charges or expenses related to ladders and scaffolding requirements. Most residential costs would fall in the range of $6.00-$8.00 per square foot.
In summary, it is crucial to identify your needs. The three major components are very different in terms of the issues that they can create. If fade protection is your primary concern, then a dark or reflective film would not be appropriate; conversely, if glare reduction is the main issue, then a dark or reflective film would be required.
