Sunwo GD75 Photochromic Window Film (Fixed Width 1.52M x Custom Length)

 GD75 photochromic window film is an environmentally friendly material that automatically reduces light transmittance and lowers temperature. It boasts excellent UV and infrared blocking, heat insulation, and light transmission properties, making it suitable for most glass applications. The photochromic window film significantly blocks infrared rays from entering the room, effectively reducing air conditioning load. This means customers can achieve a constant temperature with less air conditioning energy consumption, thus helping to save energy. Simultaneously, it also features UV protection, anti-glare, and anti-condensation functions, contributing to improved indoor comfort.

 Product Features:
 Intelligent temperature control
 Midday/High Sunlight Hours: The stronger the sunlight, the darker the tinted glass becomes, maximizing its heat insulation and light-blocking effects, effectively blocking high outdoor temperatures.
 Early morning/evening/cloudy days: As sunlight weakens, the photochromic film automatically returns to its highly transparent state. At this time, it will not block weak natural light and can keep the indoor space bright.
 Winter greenhouse effect utilization: In cold winters, due to weaker sunlight, full-view glass covers maintain high light transmittance, allowing more sunlight to penetrate into the room, creating a natural greenhouse effect, increasing indoor temperature, and reducing the need for heating.

 Energy saving benefits
 Reduce peak air conditioning load: Effectively prevents indoor overheating caused by direct sunlight, eliminating the need for the air conditioner to operate at high power for extended periods.
 Maintaining a constant temperature: The smart color-changing film can reduce the uneven temperature phenomenon in the room, such as "extremely hot near the window and cold away from the window", making the air conditioning distribution in the whole space more uniform and saving an average of 15% to 30% of air conditioning power consumption.

 Lowering indoor temperature in summer
 Effective heat blocking: The heat in sunlight mainly comes from infrared rays. When exposed to strong sunlight, the color of the photosensitive heat-insulating film will quickly darken, greatly reflecting and absorbing solar radiation heat, preventing heat from penetrating the glass and entering the room, effectively blocking more than 80% of infrared heat energy.
 Reduce thermal conductivity: Ordinary glass becomes a large "heat source" under direct sunlight, radiating heat into the room; while anti-UV glass film can effectively block this heat energy from the outside, greatly improving the comfort of living and working.

 Preserve the view outside the window
 It changes color instantly according to the intensity of sunlight, automatically reducing light transmittance and eliminating glare under bright sunlight; it restores high transparency on cloudy days or in the evening, maintaining excellent lighting. Even when the color is changed, the full-view window film still maintains a clear field of vision and does not affect the lighting in your home.
