Energy efficient fixed roof window FNP

FNP windows are non-opening windows mounted in the roof. They provide very good lighting of the interior and contact with the external environment. The design of FNP windows allows for the application of larger glazing units than those fitted in opening windows.

The sash is permanently fixed in the frame by means of screws – no possibility of opening the sash, windows can be installed very low above the floor level.

The structure of the window and glazing units applied provide excellent thermal insulation properties.

Please note, standard glazing units are only suitable for installation of up to 3,000 feet above sea level.
