Internal glazed screens

Internal glazed screens are defined as a wall or partition construction, with or without glass, designed to prevent fire penetration and to carry only its own weight. At EI the temperature is tested, whereby the surface may warm up to 180 °C locally. Constructions that meet this criterion prevent materials that lie on the unheated side of the partition wall (e.g. bookcase, painting or curtains) from spontaneously igniting within the fire resistance period.



The profile system consists of solid sharp-edged steel profiles with variable depths and designs and offers a suitable solution for every fire and smoke protection situation. For fire resistance requirement EI, the T-shaped steel profile has a depth of 80 mm and a fire resistant insulator. For fire resistance EW, the profile is uninsulated and 60 mm deep.
Several innovations have been applied in the SL30® profile system to realise the functional requirements such as strength, fire resistance and glass closure in such a slim profile.

Fire Resistance UK

The MHB SL30® -system has been extensively fire tested to BS476: Part22:1987. The fire tests have demonstrated that the SL30® glazed door assemblies and interior glazed screens meet the fire resistance criteria as follows:
• Integrity: 30 minutes and 60 minutes, as appropriate,
• Insulation: 30 minutes, depending on the fire resisting glass type installed (partially insulated door assemblies) and 30 or 60 minutes for glazed screens, as appropriate.
