Why Western Red Cedar decking is the natural choice
Western Red Cedar (Thuja Plicata) decking is life affirming. It is truly people friendly. In other words cedar looks natural and feels right. Its inherent properties cause cedar decking to remain sound, solid and perform for decades. Western Red Cedar contains natural oils that resist moisture decay and infestation helping your cedar deck last.
Being very straight-grained, Western Red Cedar neither warps nor twists, keeping the integrity of your cedar deck intact for many years to come. Its rich and variegated colouring ranges from pale saffron to a deep honeyed ochre that, over the years, gives way to an attractive patina of silvery grey. In fact, nothing grows old more gracefully than western red cedar. It is a good insulator, so compared to composites or plastic alternatives; Western Red Cedar keeps your deck surface cool on a hot day, yet doesn’t feel chilled on a cool night.

Deck Building – Practical Concept & Design Considerations
- Examine your available space. Consider special features and constraints, including views, elevations, privacy and quiet enjoyment.
- Think how you can extend your daily use. Provide shelter from prevailing winds or hot summer sun by incorporate wind screening or adding a pergola.
- Decide how the deck will be used; anticipate traffic flow, seating areas, BBQ placement, daily needs of common users and the type of usage.
- Multiple tiers help accommodate changes in elevation to the ground below and provide opportunity to incorporate different design features or uses for each level. Also a great way to incorporate different features for the various seasons and times of day.
- Multiple decks are also an effective way of accommodating the occasional larger user group while maintaining personable space the remainder of time.
Deck Building – Technical Details
- Cedar deck boards come in 2 primary thicknesses, 5/4X6 and 2X6.
- Maximum joist spacing for decking support is 16” and 24” respectively.
- Screws are ideal to fasten decks. Brown Ceramic coated screws work well in dry climates.
- Screws must be long enough to penetrate 1” (25mm) into support members. Penetration of minimum 1¼” (32mm) is required for structural components.
- Blind fastening systems create an attractive, fastener free deck surface. They employ metal clips and/or joist top brackets that fasten the sides or bottom of the deck board to the joists so that no fasteners are visible.
- Joist & beam design is typically a product of deck size and appropriate spans are determined once a basic design is finalized (see Maximum Span Calculator for Wood Joists & Rafters
- For covered walkouts it can be useful to install a sealed membrane underneath your upper deck with a nominal clearance to facilitate proper watershed.
- An 8’-10’ deck space is suitable for personal use. For a small family, a 10’-12’ living circle is better suited. Larger families or groupings require at least a 12’ living circle.
- To ensure good function of the prime deck area, it is essential that provision for BBQ’s, swings, hot tubs, etc. be made outside of basic seating requirements.
- Aim to offset stairs from your main living area to minimize disturbance of your prime space.
- Whenever possible, make stairs at least 4 feet wide. Anything less will feel crowded.
- The standard for deck stair designs is a 7” rise and 11” runs.
A good railing design can enhance your deck, provide safety, be used to incorporate protection from prevailing wind and sun and is often used to add a level of privacy to your outdoor living space.
Many pre-planned styles exist; however, for a custom look, there are some excellent standards readily available to help you design you own look and feel.
- For structural reasons optimal Rail Post spacing is between 4’ and 6’ apart.
- Many standard packages come in 6 foot multiples
- Common railing heights are 36” and 42”. Check building code for local guidelines.
- For convenience in snow removal, many railing designs are offered in an open base format.
- In the interest of safety for small children, Code requires uprights to be spaced at 4” or less.
- Palings come in a variety of sizes and finishes. Cedar 3X3, 2X2, 5/4X4, 1X6, square, sculptured, turned, fluted; aluminum round, flat shaped; glass panes and glass palings, custom.
- Typically, decks less than 24” off the ground do not require a railing.
- Ground surface supporting a low level deck is an option under certain conditions.
- In general, foundation depth is required to be below frost.
Note: Confirm structural requirements (loads and deflection, design of guards, foundation depth, column support and anchorage with local codes.
