The idea

How window film works

Sunlight is a mix of visible light, infrared (heat) and ultraviolet (UV). A film on the glass lets most of the visible light in and keeps a large share of the heat and UV out.

How window film worksSunlight is 3 percent ultraviolet, 43 percent visible light and 54 percent infrared heat. A film on the glass lets most visible light through and reduces much of the infrared and ultraviolet.Sunlight = 100%UV 3%Visible light 43%Infrared (heat) 54%Glass + filmMuch of the UV is reducedMost visible light passesMuch of the heat is reducedInside

The exact reduction depends on the film; each film’s specification sheet comes with your quote.

Where the sun’s energy comes from

Sunlight is a mix of three kinds of light. Together they make up 100% of the sun’s energy that reaches us.

Approximate split of sunlight at the ground (NREL reference spectrum). Window films are designed to let visible light through while reducing infrared and UV. How much depends on the film, so we share each film’s specification sheet with your quote.

Questions

Quick answers

Will film work on every window?

Not always. Some glass types, such as certain insulated, laminated or already-damaged panes, need extra care or a different film. Kexova checks this before quoting and will tell you if a window isn’t a good fit.

Will it block my phone or Wi-Fi signal?

Non-metallic films such as ceramic don’t use metal layers, so they are not expected to interfere with cell, Wi-Fi or GPS signals. Metallic films can, which is one reason we lead with ceramic.

Can I still see out?

Yes. Clear ceramic and clear safety films keep the view and natural light. Darker or reflective films change how much light and view you get; we’ll talk it through before you choose.

How long does installation take?

Timing depends on how many windows there are and how large they are. Your quote confirms it.

Do I need to call or can I use the online form?

Call Phone number or use the online quote form, whichever you prefer. Quotes and estimates are always free, and Kexova replies with next steps.

How much does window film cost?

Every home is different, so we quote each job on its own. The price depends on the film you choose, how many windows and how large they are, the type of glass, how easy the glass is to reach, and the warranty tier. Price ranges will be published here soon. Until then, quotes and estimates are always free, and a quote names the exact film.
