Plasters with microencapsul<strong>at</strong>ed paraffin have similar thermal mass properties as gypsum<br />

boards and they can be used as conventional plasters. They can be used to replace<br />

conventional plasters in internal thermal insul<strong>at</strong>ion systems.<br />

The he<strong>at</strong>-storing capacity of a PCM-plaster can be varied by changing the thickness of the<br />

plaster. (BASF 2011)<br />

3.8.1.4 Example uses of PCM’s -Translucent wall elements<br />

An example of a commercially available PCM-applic<strong>at</strong>ion is the GLASSX crystal. The core of<br />

this system is a PCM salt hydr<strong>at</strong>e, which is used as the storage m<strong>at</strong>erial. Salt hydr<strong>at</strong>e stores<br />

the solar radi<strong>at</strong>ion energy and releases it l<strong>at</strong>er as radiant he<strong>at</strong>. System has also overhe<strong>at</strong>ing<br />

protection with the help of prism<strong>at</strong>ic glass. The prism<strong>at</strong>ic glass blocks the solar radi<strong>at</strong>ion in<br />

summer (<strong>at</strong> angles more than 40 °) and allow the radi<strong>at</strong>ion to pass through in the winter.<br />
