<strong>MMC</strong> – Phase Change Materials (PCM’s):<br />
23 (25)<br />
Phase Change Materials (PCM’s)<br />
Thermal Mass, as its name implies, involves<br />
using ‘mass’ to absorb & release heat to help<br />
regulate our buildings.<br />
PCM’s provide a lightweight solution which<br />
has been termed ‘lightweight <strong>the</strong>rmal mass’<br />
or ‘virtual mass’ and <strong>the</strong>re are a number of<br />
products which are becoming mainstream.<br />
PCM’s are ones which change <strong>the</strong>ir phase<br />
from one state to ano<strong>the</strong>r when absorbing or<br />
releasing energy. – Water / Ice / Water<br />

new PCM’s are now being put in fire proof<br />
structural & non structural boards.<br />
