- Almost all window films will block UV by 99%, thus making this component almost irrelevant.
- The darker films will almost always block more heat than the lighter products, since they remove more of the visible light. This is why dark "car tint" blocks more heat than the lighter shades.
- Reflective window films often provide the highest heat reduction numbers because they reflect the heat away before entering the penetrating the glass.
- Films that block or filter high amounts of IR light can also provide good performance without the loss of too much light.
Finding the right combination for your specific needs is the key to a good balance. For example, our ASWF Day Dream 15 will block as much 75% of the sun's heat by reflecting a large portion of the heat at the window surface, but will also reduce the volume of light entering your windows making some rooms darker. On the other hand, our Firewall 70 and Nova 70 will allow in a greater amount of light. While the heat reduction performance is not the same, it will none the less reduce the over all volume of heat coming in.
When considering which product is right for you remember, more expensive does NOT mean better performing. Nano-ceramic window films are effective, but often do not provide a very good return on investment. Be a wise consumer and look closely at the numbers. "Brand name" products often cost much more and in the end, you don't receive any additional benefit.
