Double door with no priority direction of opening

A double door with no priority direction of opening looks identical to double hung doors from the outside, except that it has a rounded joint between the two leaves.

These two leaves are identical in construction and this joint makes it possible to open either leaf independently of the other, whereas with conventional double doors one of the two leaves is always fixed.

When is a double door with no priority direction of opening required?

Double doors with no priority direction of opening are frequently used in busy places such as car parks, railway stations, schools, building corridors, etc. They offer an attractive ‘frequency of use’ performance and great mechanical resistance.

Multiple bespoke performance features

In addition to the basic features of the Metal+ door, you can add several performance features… which can be combined!
For example, it is possible to have a door which is fire-resistant, burglary-resistant and provides acoustic protection at the same time!
