BREDI® offers a comprehensive range of thermally broken windows and door known as BREDI-
S® and BREDI-H® These systems designed and tested to maximize thermal performance and
meet contemporary aspirations for energy efficiency. BREDI® residential window and door
systems deliver up to 33% better efficiency than comparable double glazed aluminium windows
or doors.

4.3 Material Components/Denitions
4.3.1 Alloy Aluminum alloys are alloys in which aluminium is the predominant metal. The
typical alloying elements are copper, magnesium, manganese, silicon, and zinc. Selecting
the right alloy for a given application entails considerations of its tensile strength, density,
ductility, formability, workability, weldability, and corrosion resistance. In aluminum
proles systems the most used alloys are 6060 and 6063.
