The new apartment building in Markt Schwaben near Munich not only required a great deal of finesse from the planners due to a triangular building plot, but the Munich-Freilassing railway line directly bordering the property and the light railway station in the immediate vicinity also posed challenges, especially in terms of noise protection.

The building, with its 137 flats measuring around 50 m², had to meet the high sound insulation requirements imposed by the railway traffic. For this reason, the planners decided to provide all flats with loggias equipped with sliding glass elements to shield the living spaces from the noise.
What was the decisive aspect for the planners in choosing GM Toproll 6/8?
In their search for a suitable system, the planners came across GM Toproll 6/8 from Glas Marte. This is a frameless sliding system for glass elements that can be used to keep the weather off balconies, patios and terraces.
The sliding system from Glas Marte is hung at the top and can be designed in two, three or four panels. The doors can be slid to the right and left, with an opening of the glazing of up to 75 per cent. This prevents heat from building up behind the glass in summer. To keep out unwelcome guests, the glazing can be locked by means of a plug-in bolt or a push cylinder lock.
Can differences in height also be compensated for with GM Toproll 6/8?
Glas Marte / Lothar Hennig
Yes, a decisive factor in the planners' decision to use GM Toproll 6/8 was in fact that the system can actually compensate for larger differences in height. The loggias are designed as precast concrete elements that are suspended in front of the facade. Calculations showed that the cantilevered precast elements on which the glazing rests could settle by up to 8 cm due to external influences, which the planners had to take into account.

Lehmann Stahlbau GmbH from Geretsried was commissioned with the assembly of the sliding glass elements. Managing director Heinz Lehmann: "It took us two weeks just to measure the loggias, but thanks to the sliding elements from Glas Marte, the installation was relatively easy."
With this system, the glass is held in place in the upper runner by bonding and additionally by a mechanical safety device with bolts. The sliding doors are thus not held in place only by adhesion or simple clamping. This ensures an exact glass position and the glass does not slip. In addition, the glass is mounted in the centre.

The upright positioning of the glass elements is based on a simple principle: two rollers on two runners. Although the Toproll system is designed to compensate for larger height differences, this was not sufficient for the installation in Markt Schwaben.
Does Glas Marte also offer custom solutions?
Due to the use of the building, even greater deviations had to be expected. For this reason, Glas Marte produced a special solution in which the top track is embedded in a pre-assembled U-profile and can compensate for any unevenness in the ceiling area by means of different recess depths.

Due to the proximity to a busy railway lline, increased vibrations and movement of the building are to be expected. For this reason, Glas Marte also developed a new bottom track.
