This is about sealing between walls and window frames.
"Dans le cas d'un mur plein, il est conseillé de créer une chambre de décompression entre le resserrage extérieur avec le gros-œuvre et le resserrage intérieur."
I'm not sure what this gap would be called in English, but suspect that it would be called a "compression gap". However, I cannot find any confirmation for this or any alternative. As it is between the interior and exterior sealants, I don't think you could call it a "movement gap".

Note from asker:
| Thanks Liz and Bourth. I think either "air space" or "air gap" should do, though the latter term is applied to the space between glazing panes, it should be obvious from the context that this is different. |

Comment: ""Air gap" was what I used."

Note from asker:
| Thanks kashew, but not really: it is a gap between two flexible seals. |

La coulisse remplit la fonction de rupture capillaire, de chambre de décompression et de canal d’évacuation :
a- elle interrompt le passage de l’eau au travers des matériaux,
b- elle évite que l’eau qui a pu traverser la paroi extérieure ne soit projetée par le vent sur la paroi intérieure

it's not just a cavity is it?

Do I have Cavity Walls? | Thinkinsulation

Cavity walls didn't really start to be used in general building construction until the ... walls because they have an air gap between the external and internal wall.
I am only going by the first "French" picture

Note from asker:
| Thanks Liz, but note that my question is not about cavity walls but specifically relates to installation of windows in <b>solid</b> walls. The function of the air gap is quite different in the two applications. |
Discussion
Avec les châssis anciens, le joint entre le châssis et la maçonnerie était habituellement réalisé au moyen d'un mortier au ciment, souvent fendillé avec le temps et donc insuffisamment étanche.
On peut réfectionner ce joint. On procède en 4 étapes :
On dégage le joint existant (mortier ou mastic), y compris l'éventuel fond de joint.
On nettoie et on dégraisse les lèvres du joint.
On réalise un fond de joint (pour autant que l'espace vide soit suffisant), par exemple, en plaçant un préformé de bourrage à cellules fermées.
***Dans le cas d'un mur plein, il est conseillé de créer une chambre de décompression entre le resserrage extérieur avec le gros oeuvre et le resserage intérieur.***
L'injection de mousse de polyuréthane n'est pas conseillée, car, de par son caractère expansif, peu provoquer des dégâts (arrachement, ...).
On applique sur ce fond de joint un mastic élastique (thiokol ou mastic silicone) en veillant à assurer un bon contact entre les lèvres.
