Information on Siding Contracting and Building Envelope

In British Columbia, adhering to building codes for the construction of a sound building envelope is paramount. These codes provide standards and regulations to ensure structural integrity, energy efficiency, and occupant safety. When it comes to siding and enclosing a building, following certain dos and don'ts is crucial.


  1. Weatherproofing: Properly install weather-resistant barriers to prevent water infiltration and moisture buildup within the walls. Tyvek, Taping seams, Blue skin around windows, Caulking and Appropriate flashings.

  2. Quality Materials: Choose durable siding materials suitable for BC's climate, such as fiber cement, brick, or stone veneer, to withstand varying weather conditions.

  3. Installation Techniques: Employ correct installation methods to ensure a tight seal and prevent gaps where water or air can penetrate.

  4. Ventilation: Incorporate proper ventilation systems to prevent condensation and mold growth within the building envelope.

  5. Insulation: Install adequate insulation to improve energy efficiency and maintain indoor comfort levels throughout the year.

  6. Windows: In Canada, it is recommended to aim for a U-factor of 1.4 W/m2K or lower for windows and doors. The U-factor of windows and doors measures their insulation efficiency. Lower U-factor values indicate better insulation, reducing heat transfer and energy loss, thereby improving energy efficiency and indoor comfort.

  1. Ignoring Drainage: Neglect proper drainage systems, which can lead to water pooling and damage to the building envelope over time.

  2. Using Poor Quality Materials: Avoid low-quality siding materials that may deteriorate quickly or fail to provide adequate protection against moisture and pests.

  3. Skipping Inspections: Forego regular inspections of the building envelope for signs of damage, leaks, or structural issues.

  4. Overlooking Building Codes: Disregard local building codes and regulations related to siding and enclosure, risking fines or project delays.

  5. Incomplete Sealing: Fail to properly seal joints, corners, and openings, leaving gaps that can compromise the integrity of the building envelope.
