The solar control film, easily applicable on window glasses, has the property of reflecting part of the solar radiation received, decreasing the amount of energy that passes through the glass.
Solar films block 99% of UV light that fades furniture
Films add security, slowing down a break in and holding shards together if the window shatters.
While mainly it is a retrofit product, some films can make a low-cost new window as efficient as a low-E, triple-pane unit
Overheating is reduced as well as air conditioning needs
Increase internal comfort
Some window manufacturers warn that films will void their window warranty; however, several film manufacturers offer to match it
Certain lites, latches, and frames make installation difficult, and a bad application can leave glass looking bubbly
Most homeowners are skeptical of the benefits, making film a hard sell that requires education
It can block a great part of natural light, increasing lighting needs
Low investment. The approximate cost of low emissivity layers is 20 €/m2, although it varies for each type of layer. Savings of 1 to 14 €/m2 are expected. Window films can cut utility costs by 30% to 40%. It is much cheaper than replacing windows.
