English

Subject field(s)
  • Roofs (Building Elements)
DEF

A wall of wood or masonry built above the level of the roof, surrounding a roof opening such as for installation of roof fans or other equipment, and at expansion joints in the roof deck.

CONT

Joints always constitute weak links in an assembly. Therefore it is good practice to locate them on top of a curb. The curb is built directly on the roof deck and is anchored to it. Along an expansion joint, the curb consists of two separate frames, one on each side of the expansion joint, with a gap for movement in between. On each side of the curb, the roofing membrane is turned up the cant, where it is lapped by a separate base flashing membrane, which extends to the top of the curb.

Le groupe réfrigérateur comprend un compresseur, un échangeur secondaire, une turbine de détente entraînant le compresseur et un séparateur d'eau.
