Ductwork may make noise as it expands and contracts during heating and cooling cycles.

Ductwork shall be constructed and installed to prevent "oil canning".

Heat diffusers, cold air return grilles and ventilation intake grilles shall be installed securely and be generally flush with the adjacent surface. Minor gaps between the diffuser or grille and the adjacent surface are acceptable.

Insulating glass units shall be free from condensation between the panes.

Doors shall not warp to the extent that they become inoperable or cease to be weather resistant. Doors between a home and an attached garage must be maintained to be gas-proof.

Siding shall be installed to accommodate thermal movement and anticipated shrinkage of the structure to which it is attached. Siding shall be free from bows and waviness when installed in accordance with the manufacturer’s specifications. Where local distortion is caused by bowed framing, the deviation of the bow shall not exceed 20 mm from the specified plane.

Wood or hardboard or panel-type siding shall be installed in accordance with the manufacturer’s specifications and the Building Code with gaps at joints to allow for expansion. Joints shall be suitably protected to prevent water penetration.
