The design is so innovative that despite the relatively narrow profile, it is possible to use triple glazing with modern glass panes. Thanks to smart fastening techniques, presents a clean and proper fitting. Replacing old windows with modern MARKAL 76 windows is therefore a neat task.

The new MARKAL 76 doesn't compromise but offers all the advantages of a modern frame. From design to operation, construction physics and insulation values in terms of environmental protection and value conservation, it meets not only current but also future requirements.

Of course, modern three-fold or specially functional glazing up to 48mm thick can be used in MARKAL 76. The result: On the one hand, the valuable heating energy is not lost, and on the other, the solar heat penetrates into the space through the large solar windows . It is impossible to save energy in a more beautiful and simple way

The 7 chambers were designed with the latest methods and provide high thermal insulation, optimum stability and maximum lifting power for heavy loads (heavy glazing)

Highly energy efficient double-sealing system with a total depth of 76 mm

Excellent thermal insulation values: Uf-value=1.2 W / (m²K) already in its basic version of MARKAL 76 AD

Optimum sound insulation up to 47 dB through innovative insulations

A wide range of glass options up to 48mm thickness offering the use of modern triple glazing or special functional glazing

The mechanisms are secured through multiple reinforced layers on the main areas of load holding aided by special screws

Burglar protection. Resistance category up to RC 2 (WK 2). Designed for anti-burglary mechanisms
