Addressing Rising Summer Electricity Costs: The Growing Focus on 'Heat-Shielding Sheer Curtains'

Interest in home-based 'heat countermeasures' is rising due to increased summer electricity bills and extreme heat. Since a significant portion of indoor heat enters through windows, revisiting 'window surroundings' is gaining attention.

Intellex (HQ: Wakayama City, Wakayama Prefecture; President: Taro Kimura), which operates the custom curtain shop 'Just Curtain,' is proposing heat-shielding sheer curtains as a simple, no-construction heat and electricity-saving measure.

While summer heat countermeasures often focus on A/C settings and operation, the 'window surroundings'—which heavily influence comfort and cooling efficiency—are frequently overlooked. The Agency for Natural Resources and Energy recommends cutting sunlight with sheer curtains or blinds and closing curtains during the day, even when away, to save energy.

According to the Japan Building Materials and Equipment Industry Association, approximately 73% of heat entering homes during summer cooling comes through openings such as windows. As balancing heat countermeasures and electricity bills becomes a major issue, interest in easily adoptable energy-saving measures is growing.

Just Curtain emphasizes the use of heat-shielding sheer curtains. Compared to standard options, these limit the influx of solar heat and reduce temperature rise near windows, potentially improving cooling efficiency and saving electricity.

These curtains can be easily adopted by simply replacing existing sheer curtains. Functions are diversifying to include heat shielding, UV protection, privacy, and heat retention. Just Curtain offers products with clearly stated performance metrics, such as '50% heat shielding' and '88% UV protection.' These features help reduce the load on air conditioners, leading to electricity savings.
