The "Thermal Battery" Secret: Is Armstrong's Ultima Templok the End of Overheated Rooms?

Armstrong’s Ultima Templok ceiling tiles use Phase Change Material (PCM) on their backing — a high-tech wax sealed in a pouch that melts at 72F — to absorb ambient heat during warm periods and release it during cooler periods, acting as a thermal battery for offices and basements. One 2x2 tile holds as much heat as 11 bricks without the weight, moderating temperature swings in spaces that previously suffered from lightweight construction’s tendency to absorb and lose heat rapidly.
