Behind a door that rightly bears its name is a threshold that complements it perfectly. The MACO Transit threshold combines high insulation performance with comfort and attractive design. And incidentally eliminates problems that arise in energy-efficient buildings and renovations - primarily condensation and mould.
Condensation: Why? Where? How?
Condensation forms when …
… there is a temperature difference between inside and outside.
… it is damp indoors.
Cooking, showering, ironing - this causes moisture to form indoors. The higher the indoor temperature, the greater the proportion of water vapour in the air.
If moist, warm air inside meets a cold surface, condensation forms there. Critical points are therefore cold areas such as windows, doors and thresholds where thermal bridges can occur.
The inside surface temperature plays a decisive role here: this is the temperature of the wall, the glass surface or the frame measured on the inside. If this temperature remains in the dew point range for a long time, there is a risk of mould.
Therefore: The surface temperature should always be higher than the dew point. The higher the realtive humidity in the room, the higher the interior surface temperature should be in order to avoid condensation and thus mould.
A Transit threshold ensures that thermal bridges cannot arise under a door, thereby increasing insulation and sealing performance. You can rest assured that no mould or condensation water will form. All Transit thresholds are made from PVC and aluminium and have an optimum thermal barrier: the surface temperature at the point of contact between the ground (inside) and threshold is thus always kept above 12.5°C.
No ingress of water or air
During laboratory tests, the Transit thresholds achieved outstanding values for air and driving rain. They also all possess QM 340 certification from the ift Rosenheim institute. Those who have already marked their front door with another CE threshold, can switch to MACO without repeating the tests.
Suitable for all hardware
The Personal threshold offers an array of options that you won’t want to miss. Such as metal reinforcement, which is provided for screw fixing the striker plates and concealed pivot posts, thereby ensuring additional hold and security. The cover strip guarantees an attractive design.
Both the threshold and the equalizing pieces for the frame are adapted to the geometry of the various profiles.
The Personal threshold with connection bracket enables easy sealing on the outside, thereby guaranteeing high-quality installation of the door unit.
The Transit thresholds offer all limiting sizes that are needed for the production of doors without architectural barriers. Standard-compliant in the various EU states with structural dimensions of 20 to a maximum of 25 mm.
