01

The Vitrum Group repairs damage to all kind of glass surfaces. We provide high-quality services on behalf of architects, insurance companies, general contractors, building owners, banks, property managers, insurance companies, museums, private households and many more. By using our unique and proven procedures, the repair of damaged objects can save enormous amounts of money. To ensure customer proximity and fast response time, we operate nationwide. 

We carry out projects of all sizes - from individual claims to complex tasks.

02

The procedure can be used to repair various types of injuries: 

  • Scratches

  • Burns (caused by vandalism or washout) 

  • Mechanical injuries                                                                      

  • Glass turbidity (ageing and environmental influences) 

In case of severe flex damages the process reaches its limits.

03

Where can the procedure be used?

In principle, the procedure is applied to all Glass surfaces.

For example; on windows, shop windows, glass facades, glass doors, glass systems, glazing and conservatories and much more. The field of application is therefore diverse and diversified.

04

When processing glass surfaces, a distinction is made between additives and subtractive processes. 

 

In the additive process, damage to the glass surface is filled with resin, hardened and then polished. 

In the subtractive process, on the other hand, a minimal removal of the material (glass) takes place. The glass surface is removed over a minimal area until an intact glass surface is achieved.

The predetermined breaking point (scratches) in the glass caused by damage is thus removed and the homogeneous stress distribution, as in the origin of the pane, is restored. 

Finally, further grinding and polishing achieve the complete and unclouded transparency of the glass surface.

05

Grinding and glass - is this 

compatible?

In the glass production process, mechanical processing in the form of grinding and polishing is chosen as the final step in order to obtain an unclouded view of the pane. Grinding and polishing are therefore daily practice in the production of glass.

Our process adheres to this process and is therefore ideally suited for the material glass.

06

The removal of material does not significantly change the glass surface. Machining is carried out within the permissible manufacturer's tolerances. The permissible tolerances of the nominal thicknesses for glasses are specified in standards and processing guidelines. 

 

An example of this is DIN EN 572 Part 2 float glass. 

For 8 mm float glass, a nominal thickness deviation of 0.3 mm permitted. Common depths of glass scratches vary between 0.02 and 0.05 mm. Grinding the scratch does not adversely affect the glass surface.

07

Our procedures exclude or minimize optical impairments in the sense of distortion. Our method is used to create the transition from the surface to be treated to the untreated area in such a way that distortions in the transition are prevented. As a rule, the processing of the glass is not visible or disturbing for the normal observer and thus complies with the guidelines for assessing the visual quality of glass for the building industry. 

08

- Significant reduction in costs compared to replacing the glass pane  

     

- No interruption of operation due to complex assembly work required  

 

- Repair - directly on site (no installation and removal of the glass pane (required)                                                                                                                        

- Fast response time (because measurements of the target, orders, waiting and delivery times are not necessary)                                                  

 

- No impairments      

09

Since damage to glass surfaces varies greatly in size and intensity and also the type of glass, the accessibility of the damage and other factors play a role, information on prices are not possible and would be dubious. Exact prices are only given after the damage survey.

In the case of minor damage, our employees will endeavour to provide you with the best possible information based on your statements and, if necessary, from photo documentations of the damage to show a rough price range.

As we always consider a possible replacement of the glass as an alternative, you can be sure that a restoration offered by us will pay off.
