Seth aluminium window and door system


The main aim of the design was to achieve similar or better thermal coefficients compared to existing systems, but only if the system is significantly simplified, which in turn causes a significant simplification of the technology of assembling ready-made window and door constructions and results in a large production time saving and limits the inventory of companies producing ready window constructions.

SETH – the base system from which the rest of SoEasy systems originates. It was designed to meet the rigorous requirements of construction regulations, the needs of designers and is characterised by the ease and speed of prefabrication. The folding of the frame + wing is only 83 mm.


Window frame thickness88 mm
Window wing thickness97 mm
Pane thickness21-70 mm
Coefficient of thermal permeability UfUf od 0.81 W/m2K
