Whether you are renovating or building, insulation is an important consideration. The Energeto 8000ED series meets the highest European requirements including those for passive houses and offers U-values well beyond Energy Star standards. This is made possible by innovative fiber-reinforcement and a special polyurethane foam filled profile which boots the frame's insulation ability.

Saving Energy & Money with the Energeto 8000ED

Windows and doors are typically the number one source of energy loss in homes based on studies and thermal imaging. The Energeto 8000ED profile easily solves this via a combination of advanced features , such as Ultradur® carbon fiber inserts, which eliminate the effects of thermal bridging while helping to create the multi-chamber design required for an efficient profile. Next, multiple chambers are filled with precision high-pressure foam giving the frame a substantial boost in insulation while also reducing its overall heat conductivity. 

Passive house efficiency using Ultradur® inserts and foam-insulated cavities lead to long-term savings

Reliability & Security

In addition to their superb energy efficiency, the Energeto 8000ED models also meet the highest standards of burglary protection. German made Winkaus activPilot hardware ensure durability and security with a range of further upgrade options to suit your requirements based on the window's location.
