What wood is best for exterior house?

Outdoor projects often require woods that are not treated with chemical preservatives. Three popular exterior lumber choices are Western red cedar, redwood, and cypress. Redwood is commonly used in the western United States, while cypress grows in the South and Southeast. Both species are straight-grained, dimensionally stable, and decay-resistant. However, they can split when driving fasteners and bleed tannins, making fastener and painting more problematic.

Proper prepping allows for all wood stains and clear finishes. Cypress, grown in swamps, has a conical base with roots that stand out of the water. Its sapwood is almost white, while its heartwood color varies from light yellow brown to reddish brown and dark brown. Inland cypress, with its lighter-colored heartwood, features beautiful ash-like grain patterns and accepts finish as readily as redwood or cedar.

Exterior cladding timber, such as Western Red Cedar, Siberian Larch, Alaskan Yellow Cedar, Douglas Fir, European Oak, and heat-modified timbers, must withstand various seasons and resist swelling, shrinking, and fungal attack. These timbers can seamlessly blend into various environments, providing a transition between buildings and greenery, and a welcome contrast in urban environments. Wood cladding comes in a wide range of species, each machined to a specific profile, affecting the fit and performance of the cladding pieces. With over 60, 000 species worldwide, some types of wood offer superior looks, stability, and durability, while the chosen profile can also affect performance and appearance.

What timber is suitable for external use?

Timber for outdoor use can be classified into several types. Hardwoods, such as teak, ipe, oak, and softwoods, are renowned for their density, strength, and natural resistance to decay. Teak is a durable outdoor wood with a golden-brown hue and minimal maintenance, making it ideal for furniture and decking. Ipe is a Brazilian hardwood with impressive density and natural oils, making it suitable for decking and boardwalks. Oak is known for its strength and distinctive grain, offering good weather resistance when properly sealed.

Softwoods, such as cedar, redwood, and pine, are more affordable and easier to work with. Cedar is naturally resistant to decay and insects, while redwood contains tannins that provide natural protection against decay. Pine, when pressure-treated, is cost-effective and suitable for structural applications like framing and posts. Overall, timber for outdoor use can be a versatile and cost-effective choice for various projects.

How is lumber treated for outdoor use?

Pressure-treated wood is a type of wood that has been treated in a depressurized holding tank to protect it from rot and insects. Some woods, like southern yellow pine, are better suited for pressure treatment, while others, like cedar, have natural properties that resist decay. It is suitable for all outdoor projects, provided the wood is not naturally repellant to insects and rot. There are two main types of pressure-treated wood: above-ground and ground-contact. Above-ground pressure-treated wood is ideal for outdoor applications at least 6 inches above ground, such as deck railings, fence pickets, porch flooring, and joists and beams.

What timber is weatherproof?

Water-resistant wood types and species include Iroko, Oak, Western Red Cedar, Cherry, Maple, and heat-treated woods. These woods offer excellent dimensional stability and resistance to shrinking and warping in moisture. To maximize performance, they can be further treated with a sealant. These woods are commercially available in the UK, making them a realistic option for your project. Teak, known for its natural oils, is considered the most water-resistant wood due to its natural oils. However, it is not affordable, sustainable, or easy to obtain.

What is the best wood for exterior framing?

Douglas Fir lumber is a popular choice for exterior work due to its knot-free nature and good face values. It is graded 2 (good) and 3 (common) and is used for constructing, insulating, and completing residential homes. Understanding the basics of wood framing and the different types of wood available is crucial when building a house and negotiating with contractors. Framing lumber, also known as structural wood, is ideal for broad spans and is used in various types of wood for house building and timber frames for multi-family low to mid-rise construction in the United States.

Softwood species like spruce, pine, and fir are hundreds of years old and grow in temperate climates with freezing temperatures during winter. They are light in color, straight-grained, have good weathering properties, are easy to work with, and are easy to stain or paint. It is important to differentiate between structural lumber and sawn lumber, which refers to graded pieces of wood used for framing.
