Outdoor Glass floor with slip resistance

Walk-on glass panels are given an anti-slip coating with class R11.

The spectacular new building in the form of a cube of the University of Applied Sciences Northwestern Switzerland Campus Muttenz was opened in 2018. The CHF 300 million building made of exposed concrete, glass, steel and wood has 13 upper floors, a ground floor with gallery and two basement floors on an area of 63 000 square meters.

Attached underground is an approximately 10-meter-high volume with a double gymnasium. To bring natural light into the sports hall, the architects took advantage of the building's location below the square and designed a system that is part window, part walkway. The solution not only lets natural light into the hall, but also creates a unique aesthetic for pedestrians above and viewers below. Students at the Muttenz campus of the FHNW can enjoy natural light in their sports hall thanks to this skylight system, which has been integrated into a large outdoor plaza above.

For the pedestrians on the glass walkway, however, this solution resembled a slide. Although the glass was rated R12, passers-by slid and slithered on the skylight. GriP Safety Coatings is repeatedly contacted because surfaces that do not provide the specified slip resistance when used.

The skylights were given an anti-slip coating by our GriP spray system - with R11 slip rating, which fully meets the specified slip resistance in daily use. With the coating, the transparent glass also becomes translucent.
