Think you know all there is to know about exterior cladding installation? These tips will help make every job easier without jeopardizing the quality of work.
Exterior cladding is one of the most important factors in protecting structures from the elements and giving them a finished, inviting look. It’s available in a variety of materials, including vinyl, fibre cement, metal, and wood, each offering benefits in Canada’s harsh weather.
Cladding is about more than just appearance. It needs to function as intended, protecting structures from weather exposure, and be installed in a way that meets Canadian building codes.
Of course, choosing high-quality materials from a trusted supplier like HAUS Architectural Supply can also make a noticeable difference in both performance and ease of installation from the start. But there are a few additional tips that could help you improve your process and ensure your projects remain compliant, efficient, and built to withstand Canada’s demanding climate conditions.
Canadian Building Code Basics
As a builder, you’re responsible for adhering to the National Building Code of Canada (NBC). This set of safety and construction rules guides how your projects are designed and constructed, helping builders:
- Prevent water damage
- Improve energy efficiency
- Ensure safety and structural integrity
These building codes apply to many different aspects of projects, including cladding. Exterior cladding must be installed correctly to meet NBC requirements.
Quick Refresher
The success of a cladding system depends on three core principles of installation:
- Water management
- Drainage and ventilation
- Proper fastening and spacing
Do these three basic steps correctly, and you’ll likely have a building that functions as intended and meets building codes.
Of course, details matter, and where you can gain an edge as an experienced builder is to optimize installation to create the best-performing system over the long haul. Working with a knowledgeable supplier can also help you select systems that meet code requirements and perform reliably in your specific climate.
Tip #1: Optimize Rainscreen Design for the Regional Climate
Not all rainscreens are created equal, which is especially important to understand in Canada because the climate varies widely by location. Inland buildings have different needs than coastal buildings, so you’ll need to adjust your approach depending on where you’re building.
At a minimum, you’ll need to be code-compliant, but if you want to go the extra mile, focus on preventing long-term moisture issues by:
- Adjusting cavity depth based on moisture exposure
- Consider the airflow performance of the product
- Use a more robust drainage strategy when dealing with coastal projects due to tricky wind-driven rains
Tip #2: Coordinate Cladding with Air Barrier and Envelope Strategy
Cladding is an important part of protecting a building, but it’s not the only tool you have to do so, and you shouldn’t treat it as a standalone system. Experienced builders understand that misalignment between cladding and air barrier details puts a structure at risk of condensation issues. It’s also important to focus on a comprehensive system because energy efficiency requirements in Canada are increasing.
Ideally, your goal is to create a strong air barrier that controls leakage into and out of the building. This enhances energy performance and controls moisture as comprehensively as possible.
Tip #3: Take a Long-term Approach
Over time, even the most expensive cladding systems can break down if you don’t account for movement during the installation process. Cladding materials expand and contract, and planning for that inevitability ensures that your system performs optimally over time.
To prevent warping, buckling, and premature failure, you’ll want to understand the rate at which different cladding materials move and adjust based on the specific material you’re installing. Make sure your fastening patterns and joint spacing account for real-world conditions and environmental exposure. And finally, take into account when you’re installing cladding. Doing an installation in extreme heat or cold affects the alignment.
Tip #4: Stay Ahead of Evolving Building Codes
Canadian building codes frequently change, and one of the best things you can do to be successful is to stay ahead of those codes.
Prioritizing energy efficiency and moisture control helps you avoid delays, project rework, and failed inspections, and positions you as knowledgeable and reliable in your industry. You’ll be ahead of increasingly elaborate inspections and keep projects on schedule.
