Key Features

  • High safety: Reduced risk of breakage
  • Cost savings: Production line downtimes can be avoided
  • Developmental studies by ift Rosenheim
  • Ongoing product testing by TÜV Rheinland
  • Pressure-equalised insulating glass

    Differences in altitude and climatic stresses lead to build-up of excess or negative pressure in the insulating glass. The resulting tension can lead to glass breakages and premature ageing. With SWISSPACER AIR, this tension is greatly reduced, meaning that critical situations are a thing of the past.​​

    SWISSPACER AIR equalises pressure between the surrounding environment and the cavity between the panes and therefore offers a higher degree of safety. The risk of breakage during transport over different heights is minimised. 
    The use of SWISSPACER AIR in large cavities between the panes reduces the risk of breakage due to climatic stresses and also delivers other advantages – such as improved sound insulation.
    SWISSPACER AIR is installed by screwing the component quickly and easily into the SWISSPACER spacer bar – either during manufacture of the insulating glass or alternatively in the hardened secondary sealant.
    Excellent safety​
    through reduced risk of breakage
    Large cavities​
    between the panes without risk of damage due to climatic stresses
    Defining the limits of use with the SWS AIR Simulation
    The “SWS AIR simulation” allows manufacturers of insulated glass units or window makers to very easily check whether SWISSPACER AIR is the right technology to use for equalising the pressure in specific insulated glass units. Based on specific operating conditions, the result of the simulation lets the user quickly and easily estimate whether SWISSPACER AIR can offset the climate loads when transporting units over large differences in height. The tool also calculates whether a service life of more than 15 years – pursuant to EN 1279-2 – will be achieved.

  • Installation

    The SWISSPACER AIR is installed by screwing the component quickly and easily into the SWISSPACER spacer bar. Installation can also take place at a later date in the hardened edge seal, so that the production line is not impaired by downtimes and cycle times are not impacted.

    In comparison with the production of standard insulating glass, in pressure equalised double and triple glazing, there is no filling with gas, as the gas can escape through the component. Double and triple glazing equipped with SWISSPACER AIR is ready to be transported, installed and used. It does not have to be subsequently sealed or worked on.
