Car park door
Car park doors are often fire-resistant doors with the sole function of providing protection against fires. In other words, they never need to be locked. Heinen doors can be installed…
The double hung door has the same characteristics as the single door. Double hung doors can, of course, fill far bigger openings. They are also made to measure, but as with the single doors, standard dimension ranges (height and width) enable us to offer attractive prices.
The table below, available for downloading, relates to “Type 1”, the most cost-effective solution, and the dimensional limits of the range of double doors.
Arranging the order of the door leaf closure for the double door
Double doors can be provided with a door closer on the service leaf or on each leaf. In the latter case, a closure selector is fitted to ensure that the leaves close in the right order (first the fixed leaf and then the mobile leaf) to avoid collisions or blockages.
How far do the double door performance levels go?
