- Abstract
The present research has the objective of analysing the influence of the ceramic coatings simulating the external side, and in gypsum, with different thicknesses, simulating the internal side of a masonry prototype of block seal of solid waterproof gypsum, seeking to improve the thermal performance mainly in the block joints of the block. For this, two specific test methods were used: the thermal chamber and the infrared thermography. We sought to analyse the temperature differences between the internal and external surfaces, by means of thermocouples connected in the middle of the prototype and the mapping of the temperature profile on the surface of the coating. It was verified that the addition of gypsum coatings plus ceramic improves the thermal performance of the sealing system. Noting that the thickness variation of gypsum mortar provides a gain in thermal resistance, reduction in thermal transmittance and gain in thermal capacity.
