[DeAaron]

You can open the windows at any time after applying the film. The benefits of window film are as follows: 1. Protective effect: Especially when the temperature is high, prolonged exposure of the glass can be dangerous, and the film provides protection. 2. Heat insulation and insulation effect: In summer, it can block heat from entering directly, and in winter, it can prevent indoor heat from dissipating, regulating indoor and outdoor temperatures, making it energy-saving and environmentally friendly. 3. Strong anti-explosion capability: When the glass shatters, it sticks to the film and does not scatter on the ground, providing excellent protection during typhoons or other force majeure events. 4. Privacy protection: Generally, we apply the film on the inside, which enhances privacy. It does not affect the external light of the house but reduces visibility, especially for ground-floor residents who need it more.
