PERFORMANCE GUIDELINES: 4. EXTERIOR FINISHING

4.1 Siding Is Bowed or Wavy

Acceptable Performance/Condition

Siding shall be installed in keeping with the Building Code and according to the manufacturer’s requirements in order to accommodate thermal movement and anticipated shrinkage of the structure to which it is attached. While some minor waviness may occur with temperature and moisture changes, siding shall be free from excessive bows and waviness when viewed in normal light. Varying lighting conditions can exaggerate minor variations in siding profile and texture.

Where local distortion is caused by bowed framing, the deviation of the bow measured from the specified plane shall not exceed 20 mm (3/4”) over a distance of 1.2 m (4’).

Warranty Coverage

• 12 months In-Home
• 15 months Common Property
• 2 years Cladding Detachment or Material Damage

Defects in materials, work or design supplied by the owner or damage resulting from maintenance not conducted in keeping with maintenance documentation provided to the owner by the warranty provider or builder are not covered under warranty.

Claim Response

Bowed or wavy siding exceeding the Acceptable Performance/Condition is to be rectified. Where repairs are required, colour, finish or texture may not be possible.

Maintenance Tip

Siding that is intended to have paint and/or sealer requires regular inspection and maintenance to ensure continuity of the protective layer.
