LITE–FLOOR®Xtreme is a laminated safety glass to EN ISO 12543 and employs the significantly higher stiffness and tear-resistance of the SentryGlas interlayer. The load-bearing and deformation behaviour, at 30 °C ambient temperature, is comparable to a sheet of float glass the same thickness. This results in an almost completely uniform stress distribution to the perimeter of the surfaces. Therefore, in comparison to laminated safety glass with PvB interlayers, it is possible to withstand higher loads or reduce the glass thickness.

Splinter-free and load-bearing characteristics have been certified for both short and long-term durations for linear supported walkable Interior glazing applications according to ÖNÖRM B3716-4 in Report GZ 07-0137 by DI Pfefferkorn.

2. Slip-resistance

The upper glass sheet has the function of providing slip-resistance in accordance with OIB Regulation 4, Pt. 3.1.1. For this it is possible to use either tested LITE-FLOOR Designs or deep-etched glass.

• Standard colour – partial coverage – BF 727WS

• Standard colour – full coverage - BFS910WS

• Custom colours are possible

In areas with high person traffic such as schools, shopping centres etc. We strongly recommend only using the deep-etched surface glass with tested slip-resistance.

LITE-FLOOR Designs for normal traffic levels can also have custom coloured coatings to achieve slip-resistance. A selection can be found in our LITEX colour collection [>]. Please note our cleaning instructions when using light colours [>].

Deep-etched glass are suitable for both interior and exterior applications.

3. Application technical notes

The type of glass to be used dependent on the dimensions, the service loads as well as the expected level of foot traffic. These should be determined specifically for each project.

Structural concept

LITE–FLOOR®Xtreme typically comprises two to four individual sheets. All sheets are equally load-bearing and are either SECURIT Fully Tempered or PLANIDUR Heat-Strengthened glass. The upper sheet treatment is determined by the slip-resistance classification.

Structural dimensioning

The basis for the determination of thickness is ÖNORM B 1991 and the classification of utilisation categories A to D. ÖNORM B 3716-4 requires an additional top sheet as a protective layer for Categories C and D, which may not be considered as part of the structural component.

For most applications, the structural tables for LITE–FLOOR®Xtreme are used as basis for use Categories A and B 1 to ÖNORM B 1991-1-1.

4. Design notes

Slip-resistance

The upper glass sheet has the function of providing slip-resistance in accordance with OIB Regulation 4, Pt. 3.1.1. In the explanations to the OIB, the German standard DIN 51130 – testing of floor surfaces - the associated classification into categories 10 to 13 is given. A definitive requirement from the classification should be determined by the designer in accordance with the type of use.

To determine the slip-resistance, it is important to take account of the fact that high slip-resistance e.g. R 12 or R 13 act in contradiction to the necessary avoidance of „trip-hazards“ and also affect the simplicity of cleaning. As a help to orientation, the Swiss consultancy for safety in the hotel and restaurant industry for commercial or lift areas, has identified a classification of R10 as sufficient.

Marking

In the Austrian Standard ÖNORM B 1600 – Barrier-free building - Point 3.2.4.1.5, there is a requirement for all generally accessible areas where there is an entry and exit step and or ramp to be marked with a contrasting colour (preferably yellow) stripe of at least 50mm width.

Surface durability

As the substrate glass used for LITE-FLOOR is normal commercial soda-lime glass, it can be expected that outdoor shoes will cause surface scratching and that heavily trafficked areas will have irregular wear patterns in the coating.

In contrast to floor tiles, the translucency of glass may cause irregular wear to be more recognizable. For floors with high foot traffic we recommend the use of deep-etched glass with tested slip-resistance.

Safety notes

Glass breakage is unusual under normal service conditions because of the high safety factors used in design. Should breakage occur as a result of extreme mechanical overload (e.g. Vandalism), it is important to note that:

• Glass breakage of the uppermost sheet: Although structural integrity remains, danger of injury through splinters cannot be excluded. We therefore recommend that the glass be covered.
  
• Glass breakage of the carrier sheets The broken unit should not be walked on and should be replaced with suitably safe material immediately.
  

Cleaning

Slip-resistance can only be achieved with a rough surface. The better the slip-resistance is, the more the rough surface coverage. Abrasions from shoe soles, general grime etc. cause remnants to be left in the surface coating which can only be removed with extensive cleaning methods. We therefore recommend the lowest suitable slip-resistance with our standard coating to be used. For the reasons stated above we do not recommend the use of light colours..

5. Processing

Edge-working

Standard is all edges ground flat (KGN)
Optional is all edges polished (KPO)

For edge working of all rectangular sheets (KGN, KPO) the corners are matt swiped.

Subsequent treatment of the edges is not permissible.

Edge-shift

With LITE-FLOOR it is the same as all multiple laminated glasses whereby edge shift can be expected as shown in the Handbook Tolerances. A reference edge can – when indicated on orders – be produced without a shifted edge tolerance.

Cut-outs

It is standard that all cut-outs are made with a water-jet cut (KGNW). This is the term for an edge, the surface of which has been worked along its entirety with the water-jet. Water-jet cut edges have a matt frosted appearance. Cut-outs, notches or corner cut-offs are generally carried out using the water-jet cutting technique.
