Industrial: MOL Car Carrier


Results • Gaina was formally employed in covering the deck of a

large car carrier. • Lower deck temperatures decreased from 65℃ to 38℃

and the internal work efficiency had been greatly improved.

• Normally, workers are exposed to large amounts of UV. In one week, the thermal environment changed drastically, and after a careful examination of the product it was decided to make it a standard specification. (Comments from MOL supervisor)

Goal for Using Keisoukun Gaina Temperature reduction for car carrier roof.

Museum: Todaiji Temple Museum


Results • Conserving national treasures requires a large amount of

energy for HVAC. This design case sought to reduce energy consumption by increasing the amount of thermal insulation.

• As a material that avoids condensation, Gaina has been carefully evaluated in-house for several years, and we have a high regard for its insulation properties, its ability to resist dirt, and its design characteristics. (Comments from chief designer)

Goal for Using Keisoukun Gaina Surface temperature comparison for factory roof.

Applied to Interior


Color White (N-95)

Industrial: Kansai Airport Shuttle


Results • The roof of the Kansai Airport Wing Shuttle (AGT) was

treated with Gaina. • With the area under the roof having decreased from 57℃

to 47℃, Gaina was chosen as a new technology to enhance air-conditioning efficiency and to enable energy savings.
