PCMs are used in many applications from cooling food and drinks, maintaining greenhouse temperatures, and conditioning buildings. One area that is often overlooked within the construction industry is the ceiling plane – the large surface area is ideal for PCM placement.

Lightweight construction trends shifted to thicker and tighter wall insulation, more efficient HVAC systems and more sophisticated control systems as thermal mass is removed from buildings. Installing phase change material in the built environment adds thermal mass back into the structure at a fraction of the weight of materials such as concrete. For example, one ULTIMA TEMPLOK ceiling tile is the equivalent of 11 bricks. Each ceiling tile adds thermal mass to an interior space and incrementally improves thermal stability.

TEMPLOK ceilings offer the greatest temperature moderating effects in spaces with large temperature variations. This is typically caused by the climate or the presence of heat generating sources during the day (occupants, computers, or solar load) that dissipate during the night.

In various climates, use of PCM in spaces with high heat gains during the day, like classrooms, conference rooms, perimeter offices, and lobbies can be effective. In these settings, with intermittent heat sources, the PCM can help to stabilize temperatures hour-to-hour. This can lead to reduced HVAC cycling and excess heat recovery to keep the building warmer overnight.
