Enamelled Glass

Enameled glass is widely used in facade and interior glazing as a functional and decorative element of glazing. JSC RGC offers wide options for color selection, unlimited possibilities for size selection and all possible options for finished products: from single enameled glass to enamelite in triplex and insulated glass unit, in flat and bent shape.

Enameled glass (stemalite) is a tempered or heat-strengthened glass, one of the surfaces of which is painted with opaque burn-in enamels. The color shades of enamel glass produced by RGC are available in the Color Catalog according to the RAL* scale. Stemalite is intended for decorative glazing of blind areas of building facades and premise finishing.

Production Technology:

Washed glass is supplied to the line. The desired shade of paint according to the RAL scale is applied to the glass using a roller method. During the heat treatment process (hardening/heat strengthening), the paint is burned into the surface of the glass and becomes part of it.

Recommendations when ordering:

Stemalite, being tempered/heat-strengthened glass, cannot be cut, drilled or processed otherwise, so this type of product is supplied to size.

When placing orders for stemalite supply, the following shall be obligatorily agreed upon with the Client:

Operating conditions (external/internal glazing)

Method of application (through/not through)

Paint color according to RAL scale

Application of paint to the coated side

Samples of the appearance of the future product

Quality control conditions

Technical requirements for the product

Specific requirements to determine the possibility of manufacturing and calculating the additional labor intensity of manufacturing products according to the stated requirements

Contents and place of marking

Need for an additional procedure for thermal testing of heat-strengthened stemalite (HST).

Stemalite (like any tempered glass) has a tendency to self-destruction due to the presence of nickel-sulfide inclusions in the chemical composition of the glass. To reduce the likelihood of self-destruction, heat-strengthened stemalite, at the request of the Client, can be subjected to the Heat Soak Test (HST) procedure.

Heat Soak Test:

Any tempered glass, due to the presence of so-called nickel-sulfide inclusions in its chemical composition, cannot ensure a zero probability of spontaneous destruction. To reduce the likelihood of self-destruction of glass to a minimum, tempered glass can be subjected to a special additional Heat Soak Test procedure, which consists of holding already tempered glass for many hours in a special chamber at a temperature of 290°C. If HST is required, it shall be ordered together with the tempered glass. Claims with regard to self-destruction of tempered glass that has not passed the Heat Soak Test will not be accepted.
