Wood or Hardboard or Panel-Type Siding - Joints Not Tight

Article Number

4.2

Condition

WOOD OR HARDBOARD OR PANEL-TYPE SIDING - JOINTS NOT TIGHT

Acceptable Performance/Condition

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.

Warranty

One-Year - Work and Materials. Two-Year - Building Envelope Water Penetration · Normal shrinkage of materials caused by drying after construction is excluded from the statutory warranty. · Defects in materials, work or design supplied by the homeowner and damage resulting from improper maintenance are excluded from the statutory warranty.

Action

Wood or hardboard or panel-type siding joints that do not meet the acceptable condition shall be repaired.

Remarks

Siding that is intended to have paint and/or sealer requires regular inspection and maintenance to ensure continuity of the protective layer. Wood, hardboard or panel-type siding can be expected to expand and contract with fluctuations in outdoor temperature and humidity; gaps in joints may be required to prevent buckling. Caulking or attaching battens over the joints are ways to protect the joints from water penetration. Where rain screen principles are used in the cladding design, the sealing may be behind the surface of the cladding.
