Metal Technology 4-35 Hi + Windows

Metal Technology’s System 4-35Hi+ is the perfect window system for properties which are located in remote areas where there are strong winds and heavy rainfall as they provide excellent weather performance.

When manufacturing Metal Technology’s System 4-35 Hi+ Windows, Stag Aluminium includes specially designed thermal gaskets and profiles which reduce heat loss and ensure the windows achieve excellent thermal efficiency. The windows have been accessed and meet BREEAM certification, a standard which is occasionally specified by Architects or Project Developers for certain projects where windows must achieve an ‘A’ rating.

The Metal Technology System 4-35 HI + Windows are ideal in Commercial Buildings and can be manufactured in a wide range of RAL colours and finishes.
