Focusing on the next level of excellence

An optimally designed and well-composed edge bond determines the quality and durability of a window. Only when the individual components such as spacers, sealants, desiccants, connectors and glass interplay perfectly, we can achieve maximum efficiency.

One aspect of this is the stability and mechanical properties of a window. Here, the edge bond must fulfil different demands: it must stay flexible even in extreme cold and heat to avoid glass breakage. At the same time a permanent gas tightness is required to guarantee the best insulation for long-term use. Furthermore, it must prevent incoming moisture which can lead to unpleasant milky or blind glasses as well as condensation.
Now we are working on components which are adapted to our spacers and for whose quality we guarantee. The result: higher durability of the insulating glass for long-term use – an advantage for window manufacturers and final customers alike, who can rely on sustainable products of excellent quality.
Since the improvement of the single components has reached its limits, our focus has been on the edge bond in total. The merging of the components with each other and with the sash creates new opportunities for further sustainable developments. Only then the potential of the edge bond can be fully exploited.

We have developed a solution especially directed to emerging markets where the demand for improvement of the energy efficiency of the system increasing, in line with the needs of continuous building modernization and new design requirements of architects.  

However, these markets are still mainly using traditional aluminum spacers. In lieu of this, we want to support the transition from aluminum spacers with outdated thermal values to thermally optimized edge bond solutions with warm edge spacers.   

Thermally improved, durable, and flexible in shapes. It allows our customers to take a step further to the next level of IGUs performance, reaching new levels in energy efficiency and becoming more and more competitive in their markets. 

To be precise we chose a different inox steel grade able to assure the barrier, and at the same time gaining ductability for shapes insuring a great thermal performance guaranteed by Technoform hybrid warm-edge spacers. 

The advantages of this solution are: 
  • Highest accuracy for smaller glass pane sizes  
  • A seamless integration in existing processes and cutting systems
  • Once cut and inserted between the panes, the spacer will ensure a strong improvement in IGU’s energy efficiency and durability.

New spacer solution with larger steel wires for more stability (SP18)

In today’s economic scenario, markets face challenges such as an increasing internationalization and fiercer competition; in this context glass edge bond quality needs to stand out. 

We have set our focus on the mechanical properties of our spacers to improve the durability of the system. With this new development, we achieved 20 % more stability by using larger steel wires. All transformation steps of the spacer are hence facilitated:
  • optimization of the settings of the bending machines,
  • reduction of deformation generated by the suspension of the frames,
  • homogeneous application of butyl thanks to the spacer straightness allowing a perfect hermetically sealed glass unit,
  • resistance to the twisting effect generated during handling,
  • optimization of the automatic machine use due to frame stability.
All in all, this Technoform solution stands out by greater quality and reliability and by increasing the production capacity of insulating glazing.

About us

Company details

We are your partner for durable thermally optimized edge bond solutions.

With our warm edge spacers between the glass panes, for example the Spacer M and the Spacer Precision, Technoform improves the thermal performance of the edge bond and thus guarantees gas tightness at a peak level. The effects are not only minimized energy losses. There is also a visible reduction in condensation which forms at the edge of the window and thereby prevents the formation of mold. A warm edge spacer significantly reduces the circulation of air near the window which gives you better life quality inside your home.

An optimally designed and well-composed edge bond determines the quality and durability of a window. Only when the individual components such as spacers, sealants, desiccants, connectors, and glass interplay perfectly, we can achieve maximum efficiency.

To offer a perfect fitting of our Spacers into every frame we also set new standards in surface quality and match the highest requirements of architects and building designers.

Contact us if you want to increase the quality and durability of your window, door, and facade systems through an optimized glass edge bond. As a sideline our products help to save approximately 1.5 million kWh of energy each year, which means a significant reduction of the global level of CO2 emissions.
