**3. Thermal Capacity Testing of Micronal® PCM SmartBoard™ 23**

The composite material Micronal® PCM SmartBoard™ 23, in the form of a plasterboard with the addition of a phase change material (approximately 3 kg of dry Micronal per 1 m2 of the board), was tested. According to the authors of [10], this microencapsulated paraffin avoids leakage during the liquid phase and makes heat transfer easier by increasing the contact area. The authors of [10] analyzed gypsum boards with a mass PCM content up to 45% [11].
