The alternative to fan #1: solar film
Tired of feeling hot even in the shade? Solar film is THE solution for reducing the heat entering your home while preserving natural light!
The benefits of solar film :
- Significant heat reduction;
- Maintaining natural light;
- Energy savings (less air conditioning, less fan) ;
- Easy installation and immediate effect;
- Aesthetic, discreet solution.
How does solar film work?
The secret of solar film lies in its metallized technology: tiny particles (aluminum, titanium, silver) embedded in the film reflect some of the sun's rays outwards and absorb others, preventing heat from penetrating the glass. The result? A naturally cooler home without having to live in the dark!
💡Goodto know: The more tinted the film, the more effective it is against heat! It's up to you to find the right balance between protection and natural light.
