Frequently Asked Questions
What exterior railing products does Windsor Plywood carry?
Windsor Plywood carries exterior railing components including pressure-treated and cedar lumber for traditional wood railing construction, composite deck railing systems from Trex and TimberTech, cable rail components, and aluminum railing systems. Both DIY railing component packages and coordinated railing systems with matching posts, rails, and balusters are available.
What is the required baluster spacing for exterior railings in Canada?
The National Building Code of Canada and most provincial codes require that balusters on guards and railings be spaced to prevent a 100mm (4-inch) sphere from passing through the opening. This effectively means maximum 4-inch clear spacing between balusters. Confirm local code requirements with your building department, as some provinces have additional specific requirements for stair and deck railings.
What is the required height for exterior deck railings in Canada?
The National Building Code requires guards (railings) on any deck surface that is 600mm (approximately 24 inches) or more above grade. The minimum guard height is 900mm (approximately 36 inches) for decks less than 1.8 metres above grade, and 1070mm (approximately 42 inches) for decks more than 1.8 metres above grade. Local codes and provincial amendments may specify different heights — confirm with your local building department before installation.
What is the most durable exterior railing material for Canadian conditions?
Aluminum and composite railing systems provide the best durability in Canadian exterior conditions. Aluminum does not rust or rot, requires no maintenance beyond occasional cleaning, and maintains structural integrity through freeze-thaw cycling. Composite railing from Trex and TimberTech resists moisture, UV fading, and rot without painting or staining. Both outlast wood railing systems with significantly less ongoing maintenance.
Can I build an exterior wood deck railing with materials from Windsor Plywood?
Yes. Windsor Plywood carries all the materials required for a traditional wood deck railing — pressure-treated or cedar posts and rails, decking boards for the top rail cap, baluster stock, post bases and hardware, and exterior fasteners. Windsor Plywood staff can advise on code-compliant railing design and material quantities for your specific deck configuration.
