Highly Transparent Energy-Saving Film for Windows: Refleshine™ TW32

Solar radiation entering through windows during hot seasons heats up the room, while during cold seasons, cold air occupies the area beside windows. One sheet of Refleshine™ mitigates both problems for coolness in summer and warmth in winter. This film helps create a comfortable living environment or office space while reducing power consumption.

What is Refleshine™?

The highly transparent film for windows Refleshine™ shields and insulates heat, yet it does not affect brightness in the room. Simply affixing it to window panes inside the room reduces heat from sunshine (near-infrared rays) by about 60% in summer, while it reduces the heat escape (far-infrared rays) by about 70% from the room heated up by a space heater in winter. Thus Refleshine™ maintains the room at a comfortable temperature for coolness in summer and warmth in winter, reduces use of the air-conditioning system, thereby reducing energy use from air-conditioning and the resultant CO2 emissions throughout the year. Meeting the nationwide need for power-saving measures, Refleshine™ exhibits energy- and power-saving performance all year round.


Where is Refleshine™ used?

Highly transparent and daylighting Refleshine™ ensures bright living spaces.

It is used in factories, offices and railroad cars, as well as in schools and medical/nursing care facilities that require high daylighting, heat shielding and heat insulating effects. Refleshine™ creates spaces for people to stay comfortably in various everyday situations.

What are the difficulties in developing Refleshine™?

Energy-saving films for windows are required to resist surface scratches and corrosion, and withstand dusting and similar activities. It was a difficult challenge to achieve both heat insulation and practical durability since the protective film formed over the heat ray reflecting film would absorb far-infrared rays, or heat from the heater. Using Tokai Rubber’s polymeric material blending and bonding techniques, we worked on developing an innovative design of a protective film able to provide both heat insulation and durability.

What features of this product are well regarded by customers?

The Refleshine™ TW series are well-received by our customers as heat shielding and insulating films provided with the industry’s highest practicality. Refleshine™ is appreciated as a handy commodity for renovation, which provides energy-saving air-conditioning effects and improved living spaces beside windows all year round.

On October 1, 2014, Tokai Rubber Industries, Ltd. will change its name to Sumitomo Riko Company Limited.
