Frequently Asked Questions
What outdoor building materials does Windsor Plywood carry?
Windsor Plywood's outdoor range includes composite decking, wood decking, treated lumber, wood and composite siding, stone siding, lattice panels, exterior railings, garden and landscaping materials, construction lumber, and recycled products. The selection covers decks, fences, siding, and landscaping structures from framing through to finish.
What is the most durable decking material for a Canadian climate?
Composite decking is the most durable low-maintenance option for Canadian outdoor conditions. It resists freeze-thaw cycling, does not require annual staining or sealing, and will not rot, splinter, or warp the way untreated wood will. Cedar and pressure-treated lumber are cost-effective wood alternatives that require periodic maintenance to perform well.
What is the difference between pressure-treated lumber and naturally rot-resistant wood?
Pressure-treated lumber is regular wood, typically pine or SPF, that has been chemically treated to resist rot, insects, and moisture. Naturally rot-resistant species like western red cedar, redwood, and black locust have natural oils and compounds that provide inherent decay resistance without chemical treatment. Both are appropriate for outdoor use.
How do I choose between wood and composite siding?
Wood siding has a natural warmth and beauty that composites approximate but do not fully replicate. It requires periodic maintenance, painting or staining every 5 to 10 years. Composite and fibre cement siding offer longer maintenance intervals and better resistance to moisture, insects, and UV fade. For low-maintenance priorities, composite wins; for authentic natural material, wood is the choice.
Does Windsor Plywood offer delivery for bulky outdoor materials?
Yes. Windsor Plywood offers delivery for large and heavy orders including lumber, decking boards, sheet goods, and siding. Contact your local Windsor Plywood location for delivery availability, area coverage, and minimum order requirements. Delivery scheduling is particularly important for large projects where material volume makes in-store pickup impractical.
