Departed ZZZ enroute to ZZZ2. As we were climbing through FL250; we heard a loud bang and noticed that the Right-Side B Panel Window was shattered. In less than 40 seconds; the window let go and we experienced an explosive decompression. Immediately began an emergency descent with intentions of diverting to ZZZ1. During the emergency descent; ATC was unable to hear our radio calls [requesting priority handling] until we reached a lower altitude when there was less wind noise in the flight deck. It was also hard to hear crew-to-crew communication. We were able to communicate with each other utilizing hand signals. Besides glass; the only known objects that departed through the window were: Oakley Conductor 8 sunglasses and case; Clarity Aloft Headset Case; 6 ft. charging cable for Apple products; aircraft cupholder; tinted sunshade visor; energy drink; plastic Fiji water bottle; and a can of Copenhagen Mint smokeless tobacco.
Approximately 15 minutes after departing ZZZ enroute to ZZZ1 while climbing through 25;000 ft.; we heard a loud pop and determined that part of the copilot side aft window had cracked. We slowed our climb rate and within 30 seconds the rest of the window gave way and we experienced an explosive decompression. We immediately executed an emergency descent. Crew was transmitting our intentions but with excessive wind noise; could not establish communication with ATC. After descending to [a] safe altitude and slowing [the] aircraft to minimize wind noise; we were able to establish communication with ATC and were issued a clearance to land on a visual approach to Runway XX at ZZZ1. We landed and taxied in with no further issues. Emergency and medical personnel were waiting when we arrived...
