Curtains with enhanced heat-shielding effects suppress indoor temperature rise and improve air conditioning efficiency, leading to savings on electricity bills.

In particular, "3-pleat double fullness" curtains are said to improve insulation by creating an air layer within the curtains due to the numerous pleats, making it difficult for external heat and cold to penetrate. Furthermore, the beauty of the pleats is enhanced, giving the space a high-quality and sophisticated impression. It is also recommended for those who prioritize visual luxury in addition to functionality.

Additionally, curtains with lining have further enhanced heat-shielding properties due to their double-layered structure, maintaining their beautiful appearance for a long time while preventing deterioration from sunlight.

Furthermore, tests comparing general curtains and heat-shielding curtains have shown temperature differences of up to approximately 6°C on indoor sofas, indicating that preparing before the full onset of intense heat leads to a more comfortable summer life.

*Test Content: A test simulating sunlight entering through a window was conducted, and the sofa was photographed with a thermographic camera after 60 minutes, comparing the temperature of the backrest. Effects may vary depending on the curtain.
