Tested quality
The high-performance hinge side is tested according to the testing criteria of the
new DIN EN 18126-8:2017 H3 standard. With just three screw connections of
the shear hinge in the reinforcement, 20,000 opening and closing cycles with
sash weights of up to 130 kg were completed in the test, verifying compliance
with the guidelines of the organisation Gütegemeinschaft Schlösser und
Beschläge for screwing load-bearing fitting parts on turn-tilt windows (TBDK).
A fourth screw connection of the shear hinge in the steel reinforcement enables
a load bearing capacity of up to 150 kg under the same conditions. This is why
Winkhaus can dispense with a special hinge side solution with more screw
connections.
A wide range of sash hinges
All standard PVC-U windows as well as wood and aluminium windows with a
16 mm sash fitting groove can be realised in this way. This also applies to
effective burglary protection functions (up to RC3). Two sash hinge versions are
available: One is a pin version for screwing onto the sash overlap, and the other
is a euro-groove version. The innovative euro-groove sash hinge is rolled in one
piece and therefore made entirely from steel, meaning it can bear significantly
higher sash weights. Winkhaus can also supply the products with a wide range
of powder coatings on request. The overlap sash hinges are available with
height adjustment as standard. They can also be optionally fitted with additional
turn restriction or pressure adjustment. It is easy to retrofit the hinge variants at
a later date, as the sash hinges have identical screw and pin positions.
Stable corner hinges
Winkhaus offers the matching new corner hinge in two variants: The narrow
design (12 mm wide) is used in combination with the euro-groove sash hinge.
The wide (16mm) right/left corner hinge is intended for use in combination with
the overlap sash hinge. For high sash weights, a long pin is available that
extends into the steel reinforcement.
