Energeto 8000 Model

With its 338 inch profile depth, six chambers and carbon fiber reinforcement, the Energeto 8000 is designed for new construction whose goal is excellent insulation values, including Passive Houses. Although vinyl doesn't begin with the same natural insulating properties as wood, advanced German engineering and manufacturing techniques enable the Energeto 8000 profile to achieve an R-value of 7.3 with triple glazing and warm edge spacers. Vinyl is more robust and requires little upkeep from homeowners. The use of multiple chambers and carbon fiber instead of steel make this vinyl profile both environmentally friendly and easy on your purse strings.

First-class Thermal Protection with Multi-Chamber Systems

The larger profile of the Energeto 8000, with its increased frame depth, makes effective use of the multi-chamber design principle. By utilizing innovative carbon fiber reinforced inserts, internal chamber volumes are optimized all without the disadvantages of thermal bridging from steel inserts. Fully bonded double or triple glazed units allow Energeto 8000 windows to achieve excellent passive house certified thermal Uw-values.

Multi-chamber technology and a range of glazing options to achieve R-values of 7.3

Practically no design restrictions

A huge range of options allow the Energeto 8000 to be customized to individual projects. You can choose from a wide selection of colors and decors for both the inside and outside of the frame, including different colors on each should you desire. Further upgrade options include acoustic insulation glass, concealed hinges, ornamental glass and higher security levels (resistance classes). In addition, Energeto 8000 windows can also be equipped with roller shutters, providing further privacy and burglary protection.
