Exposure test @ Miyakojima

Resin sashes and aluminum-resin composite sashes are becoming more popular in order to improve their heat insulation performance, but in order to confirm the UV weather resistance of vinyl chloride resins, exposure tests are being conducted at our test centers in Miyakojima, Tokyo and Okinawa. This year, the 5th year measurement was carried out after the declaration of the state of emergency was lifted. Since Miyako Island has a lot of airborne salt, the barbed wire was not made of steel but made of glass fiber reinforcedresin.
