Which is the better choice: PIR insulation or another type of thicker boards?
As a PU insulation has a very low thermal conductivity one only needs to choose a minimal material thickness in order to achieve the required thermal efficiency. This is a considerably lower thickness than in case of the most products of the competitors indeed. On the one hand, it has a positive impact on the room use and the structural requirements: the whole masonry requires smaller width, the cornice smaller depth, the fixation smaller length and so on. It affects the expenses and makes possible the best use of the available building, site and/or the living environment. These factors are worth considering whilst choosing as well.
