The Attica explained.
So simple that anyone could have invented it. Nevertheless, we were the first.
Overtec consists of a single-shell, weather-resistant wood cement board (3), usually two metal angles (4b), which rest in a milling on the outside (11) and a parapet cover plate (17). The attic is placed vertically, as an extension of the outer edge of the wall (5b). It sits either directly on the wall (5b) or on the already concrete ceiling (9). While the parapet plate (3) is between 30mm and 40mm thick, the cover plate (17) is between 24 and 32mm thick. All steel angles (4b) are weather-resistant, hot-dip galvanized. To the outside, the parapet plate (3) forms the base for the facade structure (12) and to the inside the base for the sealing (20). The parapet sheet is attached to the cover plate (17) on the top side (16).
This type of attic reduces material and saves weight. This benefits CO2 emissions and increases the roof area. Thanks to the single-shell construction, it can be installed in just a few steps and saves valuable working time.
