Optimal+

The Optimal+ system is the upgrade of the Optimal system with thicker construction of the exterior walls and thicker thermal insulation of the roof. In most cases, we meet the standards of passive construction with this system, if the proper construction of the builders’ joinery and the orientation on the plot is ensured. When choosing…

The Optimal+ system is the upgrade of the Optimal system with thicker construction of the exterior walls and thicker thermal insulation of the roof. In most cases, we meet the standards of passive construction with this system, if the proper construction of the builders’ joinery and the orientation on the plot is ensured. When choosing this system, you may also obtain non-repayable grants from the Environmental Fund in accordance with the currently applicable terms.
