EDUARD KRONENBERG GmbH has firmly established itself as the world's leading supplier of connecting elements and innovative system solutions for the insulating glass industry.
Whether the request is for straight connectors, corner keys or Georgian bar accessories, our product portfolio includes numerous variants. For all profile systems and in all dimensions, we have the right connecting element – in steel and nylon.
At the center of all projects in EK's glass business area is application technology. From a newly developed product to its continuous optimization, the specific properties of every product undergo countless series of internal tests using various test methods. These tests enable us:
[Bend & Connect]
Regardless of type, width and material, straight connectors from the EK STEEL and EK POLO Connect series are available in numerous designs. This means they can be used for all spacer profiles, whether standard or warm edge, for pre-fill and refill technology. All variants of the EK straight connectors – pre-inserted and used for subsequent frame assembly after bending – are characterized by reliable centering, optimal matching to the profile geometry, high stability and secure locking.
[Cut & Corner]
Easy insertion. Permanent grip. Extremely high load capacity. Features that distinguish our corner keys and custom corners. Custom corners are bendable and simplify the production of special-purpose and custom window panes, while providing superior dust-tight performance. And what’s more – once inserted, they do not shift from their original position.
GEORGIAN BAR CONNECTORS
[Assemble & Join]
The Georgian bar grids between insulating glass units should provide a tight fit, not rattle and be securely fixed. The wide range of Georgian bar accessories available from EK is designed for universal application and meets the highest standards required for Vienna Georgian bars (box section), Swiss Georgian bars, Georgian bar 2000 and 76 systems. Our innovative nylon end pieces and Georgian bar cross connectors from the EK POLO Connect series enable a Georgian bar grid to be produced in the same material as that used for the frame - they can also be used with both standard and warm edge profiles. The end pieces are designed to be pressed into place and screwed on to facilitate assembly.
Easy insertion - permanent and secure grip with no profile separation.
Pleasant handling, as there are no sharp serrated edges.
Excellent absorption of profile tolerances and trouble-free desiccant filling.
Extremely high stability for all spacer bar widths and frame sizes (incl. jumbo formats).
Pre-assembled and for subsequent frame assembly using warm edge hybrid profiles.
The right material for your application: galvanized, high-strength steel, micro-alloyed multiphase steel, carbon steel (hardened and galvanized), stainless steel or designs with black surface.
A variety of designs are available – with staggered heights – for easy insertion and a secure, durable grip in the profile.
A fast and secure filling of the hollow spacer bar is an absolute must for the efficient manufacture of the insulating glass unit. This is where the thin-walled materials of the EK STEEL Connect straight connectors prove their worth and ensure a smooth production process.
Provides a 50/50 positioning of the connecting element at the junction point and thus optimum performance. Centering ensures the connector sits precisely in the middle of the profile connection and pushing it in too far is prevented. Several versions are available – we choose the most appropriate design for the application in question.
3 SIDE SEALING
Dust-tight seal on the inner contour of the profile to the space between the panes and the butyl section along the edges: optimal positioning of the connecting element provides a perfect fit and tight profile connection. Release of dust or molecular sieve material into the space between the panes is prevented.
DURABLE SPACER CONNECTION / FRAME CONNECTION
Prevents the frame from opening during subsequent handling and ensures a long life cycle for the insulating glass unit.
are very high, especially for thin-walled profiles. The optimised design of the central rib increases the stability and loading capacity of the insulating glass unit.
Provide an optional connection for Georgian bars at the junction point. The middle section is closed to prevent dust or molecular sieve material penetrating into the space between the panes. The slots permit a fastener (pin, screw) to be used to secure the Georgian bars while maintaining stability.
Ensures a strong grip of the connecting element and thus a high load capacity of the junction point even for large and heavy insulating glass units.
To increase stability and (as a tube-in-tube system) for sealing the spine of the profile. Adjusted to fit our connectors and delivered as a single unit, which can easily be filled with desiccant.
To achieve a gas-tight unit, butyl is applied to the back plate of the straight connector. This provides a reliable seal along the spine of the profile and the adjacent side walls at the junction point.
To provide a secure grip and prevent possible removal. When used with a straight connector, the spring tongue hooks into the perforation of the profile. In the case of the corner key or model corner, the tongue provides a tight seal and permanent grip within the spacer.
Whether polyamide (PA) is used with different amounts of fibre glass (M = medium, H = hard, XH = extra hard) or anti-fog polypropylene (PP), in particular for our press-on and screw-on end pieces – we choose the best material with the highest quality.
To provide a secure grip in the perforation and to hold straight connectors, corner keys and model corners, end pieces and cross connectors in position. Lamellas prevent possible removal and compensate for any profile irregularities.
3 COLUMN DESIGN
The 3 column design of our Georgian bar cross connectors and end pieces increases stability and grip and enables Vienna Georgian bars (box profile) and numerous standard and warm edge spacers to be used for universal application.
ANTI RATTLE SYSTEM
As a result of their bellows-type design, EK Georgian bar cross connectors provide a permanent grip between the panes and thus prevent movements and rattling in the installed units – without damaging the coating on the panes.
Save your strength. All you have to do is gently push the EK connector into the hollow profile as far as the second serration. When you slide the second spacer bar over the other end of the connector, as a result of its design, the connector always takes up the correct position in the profile to produce a permanent and secure seal.
Filling the spacer frame with desiccant efficiently and safe handling in subsequent operations are guaranteed for all profile widths. The geometry of our connectors has been optimized for user-friendly handling: The serrated edges are designed to ensure that the connector sits well in the palm of your hand and can be inserted into the profile with little effort.
The standard in modern insulating glass production in all widths: stable, durable, user-friendly - with secure handling and permanent connections, made of steel or nylon.
