Serrialu complies with the CLASSE + (acronym for Product Energy Labelling System in Portuguese) certification, informing its clients of thermal comfort and acoustic gains, compared to less efficient windows.
Following national and European norms, the definition of environmental goals brought energy sustainability to the centre of the debate. Taking into account that energy efficiency of casements is one of the main points to consider in the construction or remodelling of buildings, Serrialu offers its clients a performance comparison between the casement systems it sells.
We thus embrace the compromise and the challenge to contribute towards better construction systems and reduces energy consumption. Energy costs will decrease, as well as the effort of families to heat and cool their homes.
Markets are increasingly demanding, and Serrialu follows this natural trend in its I&D department, developing new products with better energy performances and consequently, more quality.
