Five isulation chambers offer optimum thermal insulation and intensify the complete window construction. Besides the thick window frame construction the patented connection technology of frame and window frame guarantees additionally high tightness against air permeability and driving rain.

Test certificates of the ift Rosenheim proof the high quality of joint permeability (DIN EN 42), water tightness under static presure (DIN EN 86), restistance to wind (DIN EN 77) and to mechanical stress (DIN EN 107). Tests according to EN 1027 show, that even at a waterpressure of 600 Pa over a period of five minutes neither on the rear window nor on the cut edge of the sandwich panels a water penetration is detectable.

This rain-tightness of the Fech-Jet System ® was conducted by Illbruck in his own laboratory. The Fech-Jet-System® of course meets all relevant standards for thermal insulation and the new EnEV.

Construction
The Fech-Jet-System® can be manufactured as turning, sliding and tilting systems as well as with fixed glazing.I can be used not only on the outer facade, but can also be used for internal and partition walls.

Quality Assurance
The production of Fech-Jet-System® is based on the
current state of the art. There are guarantees in form of warranty deeds with a warranty period of 5 years.

The warranties referr to the requests according to RAL-
GZ 716/1 T1 and T2 inclusive of notched impact strength of the profiles according to DIN 53753, to dimensional accuracy, shock restistance in the cold, sweating as well as light and weather resistance.

RAL quality mark for installation
On the basis of the RAL quality mark "Fertigung und Montage" our company got transferred the right to use the RAL quality mark for installation of windows and doors.
