Think about your comfort



With a height of just 20 mm, the threshold meets the requirements for accessible buildings to DIN 18040-2. No additional measures required during installation. The strike plate components on French windows are flush with the threshold, which means no more tripping hazards.

Heat insulation

Outstanding thermal separation, including in the vicinity of the strike plates, thanks to the integrated solution comprising aluminium and PVC. Very good isothermic profile to reduce the risk of formation of condensation or thermal bridges.


High stability thanks to optimised distribution between PVC and aluminium components. Firm bond produced by the PVC and aluminium parts engaging on two planes.


Simplified installation thanks to screw channels. Aluminium and PVC components are supplied engaged ex-works. A protective film protects the threshold against transport and installation damage.


Compatible with all GEALAN systems with 74 mm and 83 mm installation depth. Suitable for French windows and front doors.


Existing accessories can continue to be used. New accessories for the S 9000 system are available. Threshold ridge is compatible with numerous items from the GEALAN range.


Avoid future obstacles

Easy for everyone

The word "accessibility" is used to describe ease of access to the everyday things in life – for all people equally. Because while young and healthy people may not see the difficulty that stairs, thresholds or high handles can pose, older people can regard them as unpleasant obstacles. For persons with reduced mobility, they are insurmountable barriers. That is why it is necessary to plan ahead now and keep accessibility in mind when building your house so that you can move around freely and safely in your home environment in the future also. It ultimately makes no difference whether you are considering alternatives to stairways or individual steps, low-profile threshold solutions or easily reachable and effortless or even automatic or remote-controlled opening and closing mechanisms, what is important is that you start thinking today about the obstacles of tomorrow.

The GEALAN combination threshold

First-class threshold solution, outstanding heat insulation

The new ground threshold for front door and French window elements is a key addition to the GEALAN product range. It can be flexibly used in all 74 mm and 83 mm systems for renovations and new builds and permits a barrier-free transition from the inside to the outside, while also meeting the requirements for heat insulation and impermeability.
