Okno DEF DU8 Z-Wave przeznaczone jest do montażu na dachach płaskich o kącie nachylenia od 2° do 15°. Jeżeli kąt nachylenia dachu jest mniejszy niż 2° lub wskazane jest zwiększenie kąta montażu, należy zastosować kątową ramę montażową XRD-A. W przypadku dachów zielonych, żwirowych lub wentylowanych można zastosować podstawy montażowe XRD oraz XRD/W, które podnoszą okno ponad warstwy wykończeniowe i ułatwiają prawidłowy odpływ wody. Prosta, elegancka forma okna DEF doskonale komponuje się z nowoczesną architekturą. Okno można wyposażyć w akcesoria wewnętrzne oraz markizę zewnętrzną ograniczającą nagrzewanie.

Maximum interior daylighting
Modern buildings with flat roofs do not have to mean limited access to natural daylight, as the use of properly designed windows allows interior spaces to be effectively illuminated. Thanks to specially engineered profile construction, the glazed area can be increased by up to 16%, resulting in noticeably brighter and more comfortable interiors.

Structural durability
Flat roof windows are equipped with advanced glazing units, in which the external pane is made of toughened glass, while the internal pane features P2A safety classification. This solution increases resistance to damage and, in the event of glass breakage, significantly reduces the risk of hazardous fragments.

Year‑round comfort of use
A stable frame made of multi‑chamber PVC profiles filled with thermal insulation material helps maintain proper indoor conditions inside the building. In practice, this results in improved user comfort, especially when replacing older solutions with modern windows offering enhanced performance parameters.
