ISOLAR MONOPACT®

Crystal clear security which reassures

Glass is not just a transparent material that creates brightness and an open space in interiors. On the contrary, glass can also fulfil protective functions in different ways through special finishing and processing processes. In addition to the MULTIPACT variants, the category of so-called safety glass also includes thermally tempered safety glass (ESG, ESG-H) and semi-tempered glass (TVG).

ISOLAR MONOPACT® ESG

Thermally toughened safety glass

In the pre-stressing process, the panes are initially heated and then cooled very quickly with compressed air. This “quenching” produces tensile stress in the interior of the glass while compressive stress is created near the surfaces, This makes ISOLAR MONOPACT® ESG the ideal glass for all applications involving increased structural, dynamic or thermal demands. ISOLAR MONOPACT® ESG only breaks into hundreds of blunt fragments when the stress exceeds the compressive tension created by the pre-stressing process. Enamelling, screen printing and ceramic digital printing are glass refinements which all require pre-stressing. 

Major applications for ISOLAR MONOPACT® ESG with or without printing include glass facades, glazing for fall safeguarding, sports facilities, schools, kindergartens, door systems, shop facades as well as interior construction with showers, partition walls, glass cut-outs right up to furniture glass and glass furniture.

ISOLAR MONOPACT® ESG alarm

All ISOLAR® glazing can be fitted with alarm thermally toughened safety glass. The conductor loop which is fitted into a corner of the thermally toughened safety glass pane and connected to the alarm system acts as an alarm device. When damaged mechanically, thermally toughened safety glass panes break consistently across the whole surface. So if there is any damage, the alarm loop is also damaged which then sets off the alarm securely. This system is ideally suited for both simple insulating glass and also attack resistant bonded security glass, It is tested and recognised by the VdS (Verband der Sachversicherer - Property Insurance Association).

ISOLAR MONOPACT® ESG-H

ISOLAR MONOPACT® ESG-H is a thermally toughened safety glass which has undergone a standardised, so-called Heat-Soak-Test (EN 14179). The thermally pre-stressed glass is subject to a middle oven temperature of around 290° C for a period of 8 hours.

This additional heat soaking after pre-stressing destroys any nickel sulphide gas cavities which can be present in any glass. Nickel sulphide gas cavities can lead to a spontaneous break in thermally toughened safety glass at a later date. These critical nickel sulphide cavities are not found in ESG-H which has the safety level required by legislation. Regulations require the use of ESG-H instead of ESG in windows and facades at an installation height of 4 m above ground level and for constructive glass installation.

ISOLAR MONOPACT® TVG

Semi-tempered glass

ISOLAR MONOPACT® TVG (semi-tempered glass) is a heat treated glass which has been specially developed for the building industry with high flexural strength and high temperature resistance. When a pane is broken, a number of radial cracks run out from the centre of the break towards the edge of the pane - similar to the behaviour of float glass when if breaks.

ISOLAR MONOPACT® TVG undergoes a thermal pre-stressing process, just like thermally toughened safety glass, but which is done in such a way as to the tensile stress and compressive stress is less developed. This lower level of tension compared to thermally toughened safety glass means that large fragments are produced in a “break”. Further processing into laminated safety glass leads to products which add residual load bearing capacity to the benefits of pre-stressed glass Combining the properties of flexural strength, load bearing capacity and a “coarse break pattern” makes laminated safety glass from part pre-stressed glass the ideal glass product for overhead applications, in constructive glass and for point fastened glazing.
