TOPLINE plus
The VEKA System for the best Heat Insulation

TOPLINE plus is the logically consistent development of the TOPLINE system with a special profile geometry and highly effective insulating cores. It has a deep edge cover and with its triple insulating glazing, it obtains U_W values of less than 0.8 W/m²K. Thus, it is already primed for being used in passive houses where there is no need for an active heating system neither in the summer nor the winter, and without any restrictions to modern living.

TOPLINE plus is certified by the Passivhausinstitut Darmstadt (Dr. Feist) as a window system which is suitable for being used in passive houses and complies with all requirements of DIN and Euro standards as well as with the Energieeinsparverordnung (EnEV) [The German Energy Savings Regulation] – and all this with the modern TOPLINE design.
