Phase Change Material Ceilings Save Energy

What are Phase Change Materials?

A Phase Change Material (PCM) is a substance which releases or absorbs energy at phase transition to provide useful heat or cooling.

TEMPLOK Ceilings use safe and proven phase change material (consisting of a water and salt solution) that solidifies and dissolves as it changes phase.

TEMPLOK Ceilings with advanced Phase Change Material technology are specially designed to change phase around comfortable indoor temperatures. As a building changes temperature, the PCM resists the change by absorbing or releasing heat. The temperature moderating effect can improve thermal comfort and enhance energy efficiency.

How Phase Change Material Works

PCMs are used in many applications from cooling food and drinks, to 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. Learn how the phase change material technology works within TEMPLOK Energy Saving Ceilings to cool and help regulate indoor temperature passively.
