S20 and S30 solar window films are indeed related variants designed for solar control, but they differ primarily in terms of their light transmission and shading properties. Here's a comparison between S20 and S30 solar window films:
S20 Solar Window Film:
- Light Transmission: S20 solar window film typically allows less visible light to pass through compared to S30. It has a lower visible light transmission (VLT) percentage, which means it is darker and provides more shading.
- Solar Heat Rejection: S20 films are effective at rejecting solar heat and can help reduce indoor temperatures, making them a suitable choice for locations with intense sunlight and heat.
- Glare Reduction: Due to their darker tint, S20 films can provide effective glare reduction, enhancing visual comfort by reducing the intensity of direct sunlight and reflections.
- Privacy: The darker appearance of S20 films can also enhance privacy during daylight hours, making them a popular choice for commercial spaces and residential areas where privacy is a concern.
- Aesthetics: S20 films have a more shaded appearance, which can create a sleek and contemporary look for windows. They are often chosen for their aesthetic qualities in addition to their solar control benefits.
S30 Solar Window Film:
- Light Transmission: S30 solar window film allows more visible light to pass through compared to S20. It has a higher visible light transmission (VLT) percentage, making it lighter and less shaded.
- Solar Heat Rejection: S30 films still provide effective solar heat rejection but allow more natural light into the space, which can be preferable in areas where preserving a brighter interior is important.
- Glare Reduction: While S30 films reduce glare, they may not provide the same level of glare reduction as S20 films due to their higher VLT.
- Privacy: S30 films are typically less effective at enhancing privacy during daylight hours because they allow more visible light and transparency.
- Aesthetics: S30 films maintain a clearer and more natural view, making them suitable for spaces where maintaining a brighter and more open atmosphere is desired.
In summary, S20 and S30 solar window films are related products within the same family, and their differences primarily revolve around the amount of visible light they allow through, their shading properties, and the resulting aesthetics. The choice between S20 and S30 depends on your specific needs and preferences, including the desired level of privacy, heat reduction, glare control, and the aesthetic impact on your space. It's important to consult with a window film professional to determine which variant is the best fit for your particular situation.
