FAQ

Can end consumers enquire about prices?

We ask for your understanding that as a wholesaler we do not provide information to private individuals.

Can end consumers purchase goods?

Sales to private individuals are not possible. End consumers should contact a specialist company.

Can end consumers get a catalogue?

It is not possible to send catalogues to end consumers.
In our shop, we provide all information about our products.

Can all tradesmen buy goods here?
As a specialist wholesaler, we primarily supply specialist tradesmen from the metal, wood and glass construction sectors. We ask commercial consumers from other areas to inquire on a case-by-case basis.

Can free samples be supplied?
Unfortunately, it is not possible to provide our customers with free samples of our products.

Can products be delivered by express?
Express delivery is possible within Germany via DPD. In this case, please contact our sales department before placing your order, or order directly in our online shop with the corresponding option for express delivery.

Can products be delivered to the construction site?
If you specifically request it, we will also deliver to your construction site. However, our customers must ensure that the goods can be received there at any time. As a rule, it is safer to deliver to the workshop.

Can spare parts of products be delivered?
For almost all products it is possible to get spare parts at short notice. If you need them, please contact us by phone.

Can the products be delivered free of charge?
For each package up to 30 kg we charge a flat rate for freight and packaging of 6,95 Euro / net within Germany. From 250 Euro net value of goods we deliver free of charge within Germany. Only possible island surcharges are excluded. There are no additional alloy surcharges or other hidden costs.

Can products be delivered without a minimum order value?
There is no minimum order value with us.

Can products be delivered abroad or to third countries?
Of course we also deliver goods to other European countries. Please ask for the shipping costs in advance. We will be happy to send you information. However, delivery to third countries is generally not possible.

Can image data and content be used or copied?

Almost all images were created by ourselves for a lot of money. Since a release for use of image data and content cannot usually be withdrawn once it has been given, we generally have to refuse such requests.

Can customer drawings and designs be checked?

Since different building regulations apply in every federal state in Germany, we are unfortunately unable to provide any legally binding information. We can only pass on verifiable contents with regard to existing general building inspectorate approvals and personal assessments.

Can files be obtained for transfer to construction programmes?

We have CAD drawings for our products. If required, please contact our service team.

Can toughened safety glass panes be used for fall-proof glazing?
Contrary to many statements to the contrary, fall-proof glazing with ESG-H is permissible. Since this type of glass is also specified in the documents of our glass holders approved by the building authorities, it can be used for cost-effective and legally secure glazing throughout Germany.

What is SPG | Mirror glass
Description: Float glass is flat glass which is produced in the float process. The process has been used industrially since the 1960s and currently supplies about 95% of all flat glass. According to DIN 1249 (flat glass in building) and DIN 1259 (glass), the term mirror glass stands for flat and transparent glass, but is now often used as a synonym for float glass. As a basis for flat glass in almost all areas, it is also referred to as basic glass. Preferred areas of application: Window glass, display cases, glass furniture and mirrors.

What is toughened safety glass (ESG)?
Description: Toughened safety glass (ESG) consists of a glass pane and offers increased resistance to temperature changes as well as high bending, impact and shock resistance. In the event of breakage, toughened safety glass shatters into small, partially interlocked fragments, thus reducing the risk of injury. ESG is visually indistinguishable from normal, non-tempered glass, but usually bears an etching stamp with the imprint “ESG” in one corner. In addition, tempered glass cannot be processed after it has been tempered. An attempt to cut or drill the pane would lead to its destruction. Preferred areas of application: Side and rear windows of vehicles, glass showers, glass furniture, all-glass interior doors, light cut-outs, spandrel glazing and glass walls.

What is ESG – H | Toughened safety glass with hot storage test
Description: In a small proportion of toughened safety glass panes, spontaneous breakage occurs, mainly in the first year after manufacture, due to corroding nickel suffide inclusions. By selectively promoting corrosion in a so-called heat soak test, the breakage of such panes occurs even before delivery. In this test, the tempered toughened safety glass must be heated to a defined temperature and kept at this temperature level for a certain period of time. DIN 18 516 Part 4 prescribes a holding time of eight hours at an average oven temperature of 290 ˙C (± 10 ˚C) here; Bauregelliste A, Part 1, 11.4.2 deviates somewhat from DIN and prescribes a holding time of four hours, among other things. Glass that has passed this test then bears the designation ESG-H. Preferred areas of application: Safety-relevant applications such as façade glass, structural glass elements (e.g. beams and columns).

What is TVG | Semi-tempered glass
Description: Partially toughened glass, TVG for short, is subjected to a thermal treatment like toughened safety glass.

What is TVG | Partially toughened glass

Description: Partially toughened glass, abbreviated to TVG, undergoes a thermal toughening process like toughened safety glass. However, the cooling process is slower. This results in smaller stress differences in the glass between the core and the surfaces. The bending strength is between that of float glass and that of toughened safety glass. If broken, cracks appear, which extend radially from the centre of the break to the edges of the pane, similar to the breakage of float glass. In practice, TVG is used almost exclusively for the manufacture of laminated safety glass. Due to the large fragments, VSG made of TVG has a high residual load capacity. Preferred areas of application: TVG is mainly used as laminated safety glass for overhead glazing and for anti-fall glazing.

What is VSG | Laminated safety glass

Description: Laminated safety glass (VSG) is a special form of laminated glass that meets the minimum legal requirements. It consists of at least two panes of glass, usually flat glass panes, and an intermediate layer, usually of tear-resistant polyvinyl butyral (PVB) film. It is rare that clear plastic panes are used, just as it is rare that other intermediate layers are used, for example casting resins. The VSG generally achieves a high level of safety due to the tear-resistant PVB layer and its adhesion effect. In the event of mechanical overload (e.g. impact or shattering), the glass does break, but the pieces adhere to the PVB film. This results in a residual load capacity, with the formation of splinters at the same time reducing the risk of injury. Laminated glass is manufactured under clean room conditions. In the autoclave, the glass and film are fused together under high pressure and heat to form an inseparable unit. The embedded film is usually transparent. Special effects can be achieved with matt or coloured white films. Applications of VSG in ESG (laminated safety glass in toughened safety glass) : Spandrel glazing Applications of VSG in TVG (laminated safety glass in partially toughened glass): Overhead glazing, glass canopies, spandrel glazing, passable glass, car windows (windscreens). Laminated safety glass applications in float glass (laminated safety glass in float glass): Spandrel glazing, operable glass, bullet proof glazing, bullet proof glazing or blast proof glazing.
