Benefits of Douglas fir decking
Like spruce, Douglas fir is both attractive and fairly strong. It is easy to work with hand and power tools and, when properly treated, it resists decay, mould and termites. Douglas fir is more than just an attractive timber: its longevity and resistance to rot and insects make it an ideal option for outdoor projects such as porch decking. Vertical-grain Douglas fir has been a popular choice for porches on older homes for more than a century. Builders chose it then for its availability and durability, the same reasons it is successful today.
Why is Douglas fir an excellent choice for decking?
First, it is a dimensionally stable wood with few knots. Like all species, it expands and contracts with moisture, but it does so evenly. It rarely warps, especially if you choose boards with a distinct vertical grain.
In addition, its heartwood is naturally resistant to mould, decay and insect attack. According to a study by the University of California Division of Agriculture and Natural Resources, untreated Douglas fir can last 10 to 15 years outdoors.
Tips for Douglas fir decking
If you plan to use the wood outdoors, it is generally advisable to treat it with a product that extends its service life. According to University of California studies, Douglas fir treated with ACQ (a water-based fungicide and insecticide made of copper oxide and a quaternary ammonium compound) can last 30 years or more. Paints, stains and exterior finishes will also help your Douglas fir stand the test of time.
Now that we have shown that Douglas fir can withstand the weather, let's look at what you can do with it. Cladding is a common use of Douglas fir. Real wood cladding is not only more authentic for older homes but also more visually appealing than aluminium or vinyl siding. Whether you are renovating an older home or building a new one, Douglas fir cladding will outlast synthetic alternatives with proper maintenance.
Other uses of Douglas fir
Douglas fir is also an excellent choice for an often-overlooked part of a house: the soffits. The soffit is the underside of the roof overhang, the part of the roof that projects above your head when you stand outside. By using attractive solid wood for your soffits, you can turn a discreet architectural requirement into a subtle design feature that enhances your outdoor living space.
For outdoor living, we have already mentioned porches, but don't limit yourself to the front of the house. Once your Douglas fir decking is installed, you can go further: the current landscaping trend is to treat the whole backyard as an extension of the home, creating an "outdoor living room".
As Douglas fir is more affordable than redwood or cedar without compromising on durability or appearance, creating an outdoor living space becomes a reality. A Douglas fir gazebo for relaxing outdoors, a covered barbecue area or a trellis for climbing plants: whatever you imagine, your builder can create a Douglas fir structure to meet your needs.
