Out of the Sun Solar Window Film – Product Specifications and How It Works
Solar window film is a specially designed thin film applied on the interior- or exterior side of your windows and doors. This is to effectively reduce heat, glare, and harmful UV rays while maintaining your view and natural daylight. At Out of the Sun in Spain, our high-quality solar films offer excellent heat control tailored for the intense Spanish sun.
How Solar Window Film Works
Firstly, solar window film works by filtering the sun’s rays before they enter your living space. It reflects and absorbs a large portion of the sun’s infrared heat. This is the invisible energy that causes warmth in your rooms. At the same time, it blocks up to 99% of harmful ultraviolet (UV) rays which cause fading of furniture, flooring, and harm to your skin.
Secondly, the film’s advanced materials allow most visible light to pass through. So, your rooms remain naturally bright and inviting. In fact, you will hardly notice any difference from the inside in terms of daylight or views. This means that anyone concerned about losing natural light can rest assured that our films preserve your sunshine without the intense heat.
Moreover, our films come with a reflective silver or neutral finish outside that increases privacy during the day/ This while still maintaining a clear view from inside your home. This blend of comfort, protection, and aesthetics makes solar window film a smart solution for Spanish homes.

Interior window film or exterior window film ?
Some glass types require solar window film to be applied on the inside (interior) of the window, while others need the film on the outside (exterior). Usually:
Interior film is used on most standard residential windows where the glass surface is accessible from inside. The film goes on the inner glass surface, protecting it from wear and weather since it’s indoors. This installation is easier and lasts longer because it’s shielded from rain, wind or dirt.
Exterior film is needed for windows with special glass types like laminated or tempered safety glass or certain types of coated or treated glass. Also, windows hard to reach inside (like skylights or large commercial windows) often get exterior film. Exterior film faces the weather and needs to be tough and weather-resistant. It blocks solar heat before it hits the glass, giving better heat reduction but is more complex to install and may have shorter lifespan due to exposure.
How to check by sound (simple test):
You can tap the glass gently with your finger or a small object and listen carefully. Laminated or safety glass tends to produce a duller, softer sound because it has a special plastic layer or treatment. Normal glass sounds clearer and sharper. If your windows sound like soft or muted taps, they might be safety or laminated glass which usually require exterior film.
For most standard clear glass windows accessible inside your home, interior film is best. If you have doubt, a professional can help identify your glass and recommend the right film and installation method.
In summary:
- Standard glass + easy inside access → Interior film (easier, longer-lasting)
- Laminated/safety/coated glass or hard-to-reach windows → Exterior film (stronger protection, better heat rejection, needs weatherproof film)
Silver 20 Interior
Silver 20 interior solar window film is a high-performance metallized polyester film designed for indoor window installation.
It blocks up to 77-80% of total solar energy, reduces glare by around 78-81%, and blocks 99% of harmful UV rays. Despite its strong heat rejection, it still allows about 19% of visible light to pass through, maintaining natural daylight inside your home.
Additionally, it offers daytime privacy with a reflective silver finish outside, while preserving clear views inside.
This film helps keep interiors cooler in summer, protects furnishings from fading, and reduces air conditioning costs, making it a premium solar control solution for hot climates like Spain.

Silver 35 interior solar window film is a premium metallized polyester film created specifically for indoor application on windows.
It effectively blocks approximately 65-70% of total solar energy, cuts glare by 65-70%, and filters out 99% of damaging UV rays. Although it provides strong heat rejection, this film permits roughly 35% of visible light to enter, ensuring your space remains bright and naturally lit.
Moreover, its reflective silver exterior grants daytime privacy while retaining clear outward visibility.
Ideal for hot environments like Spain, this film keeps rooms cooler, protects furniture from sun damage, and helps lower cooling expenses, offering a high-quality heat control solution.
Silver 50 Interior
Silver 50 interior solar window film is a high-quality metallized polyester film designed for indoor window application.
It effectively blocks approximately 50-54% of total solar energy, reduces glare by around 40-47%, and filters out up to 99% of harmful UV rays. Despite its strong heat rejection, about 47-52% of visible light still passes through, ensuring your living spaces remain bright and naturally lit.
Additionally, the film features a reflective silver exterior that provides daytime privacy without compromising outward views.
Perfectly suited for the intense sun in Spain, this film keeps interiors cooler, protects furnishings from fading, and helps reduce air conditioning costs.
Silver 20 XTR
Silver 20 XTR window film is a premium, metallized reflective film designed specifically for exterior application on windows and doors. Unlike typical interior films, this film must be installed on the outside surface of your glass because it is engineered to withstand harsh weather conditions, including rain, wind, and UV exposure. Installing it outside ensures maximum durability and optimal performance in reflecting solar heat before it even passes through the glass, helping keep your interiors much cooler.
This high-performance film reflects up to 83-86% of total solar energy, blocks 99.9% of harmful UV rays, and significantly reduces glare by approximately 83-84%. Despite its strong heat rejection, it transmits about 10-15% of visible light, maintaining natural daylight inside your home while providing excellent daytime privacy thanks to its reflective silver finish on the outside.
Regarding safety glass, this type of glass is designed to hold together when shattered. It is usually either laminated—two layers of glass bonded with a plastic layer—or tempered—heat-treated to break into small, less dangerous pieces. Solar window films like Silver 20 XTR increase safety by holding broken glass fragments together in case of impact or accidents. This helps protect people inside from injury and secures the property from break-ins or damage.
In simple terms, Silver 20 XTR is applied outside because it is tough and weather-resistant, offers superior heat and UV protection, reduces glare, and improves privacy without darkening your indoor light. Plus, it enhances your windows’ safety by reinforcing the glass structure.
If you want a durable, effective, and safe heat control solution for your windows and doors, the Silver 20 XTR exterior window film is an excellent choice for sunny climates like Spain.
Titanium XTR and Interior
Silver TitaniumXTR window film is a cutting-edge exterior solar window film designed to deliver long-lasting durability and excellent solar heat control. Unlike interior films, TitaniumXTR is applied on the outside of your windows and doors to maximize performance and withstand weather exposure such as rain, wind, and UV rays. This exterior installation method ensures your film stays effective for years, reflecting a large portion of solar heat before it even reaches the glass.
From the outside, TitaniumXTR film has a sleek, neutral grey appearance with a moderate reflective finish that provides high privacy and a modern, professional style. It looks smooth and uniform, blending well with most building facades without appearing overly dark or mirrored. On the other hand, when viewed from the inside, this film is designed to be low reflective and quite clear, allowing you to maintain natural daylight and outside views with minimal change in brightness.
Simply put, the difference in look is that from outside the film offers privacy and a stylish tinted effect, while from the inside it remains subtle and mostly transparent to keep your rooms bright. This balance makes TitaniumXTR ideal for residential or commercial properties in sunny climates like Spain, where heat reduction and UV protection are essential but preserving daylight and outward views matters just as much.
In summary:
- TitaniumXTR is an exterior film with strong weather resistance and long life.
- Outside, it looks like a sleek grey tint providing privacy and heat reflection.
- Inside, it stays clear and low reflective, maintaining daylight and views.
- The exterior installation ensures better durability and solar performance than interior films.
