PUSH OUT CASEMENT WINDOWS
Outward opening casement windows allow to take advantage of the whole space inside the building. Opening such windows does not cause the need of removing the flowers, decoration, curtains or blinds. Such windows can either be fully opened or just a little for ventilation thanks to the friction brakes, restrictors or the hinges. The combination of comfort of use with the highest quality of manufacturing, very good tightness and energy efficiency cause that it is the most common window among all Drewexim's customers.
TYPE I (DUN114)
Outward opening casement window where the sash is flush with the frame is the most popular type of casement window among Drewexim's customers. All the frames are very slim which gives the impression that the window is bigger than it actually is offering at the same time very interesting aesthetic aspect. The hinges used might be traditional exposed butt hinges (brass, stainless steel or powder coated with any colour) or concealed friction hinges fitted on the top and bottom of the sash. This type of hinges allow to push the sash aside a little bit to access the external side of the window for cleaning. To suit customers' requirement even better this type of windows is offered in two shapes of the frame and sash: square - modern and decorative - traditional.
TYPE II (CAS68)
Rebated outward opening casement window where the sash overlaps the frame is a typical system for the UK market and this is where this window is the most popular. It is equipped with concealed friction hinges which allow for cleaning the outer part of the sash (easy clean hinges). Additionally this type of window may be equipped with fire escape hinges and so the window might be an emergency exit.
TYPE III (NOR93)
Scandinavian outward opening casement window is again the type where the sash is flush with the frame. However, this type is common mainly in Scandinavia.

It is possible to use opening restrictors to block opening the the window in full especially by children or in case the window is installed rather low in the wall. Normally Drewexim uses multipoint locking espagnolette and handles but it is also possible to use single point locking traditional hooks. Window of this type with triple glazing achieves the whole window U value of Uw=1,15 W/m2K certified by SP Institute in Sweden.
