Which Type Of Wood Is Ideal For Exterior Cladding?

Western Red Cedar is the most popular timber for external cladding projects due to its affordability and durability. Other options include pre-aged softwoods, modified timbers, and hardwood solutions like oak. Softwood is a good option for those on a budget, as it is stable and can transform the exterior appearance of buildings.

The best type of wood for exterior cladding is either a softwood (like Red Cedar or Larch) or a modified timber such as Accoya. Red Cedar is considered the most stable of the softwoods and can be left untreated, ensuring the cladding boards stay. Wood cladding for exterior walls is a stylish and sustainable way to protect buildings from the elements while adding a warm and natural look.

Some popular species for exterior cladding include Western Red Cedar, Siberian Larch, Alaskan Yellow Cedar, and Douglas Fir. These species don’t require any preservative treatment and are naturally resistant to insects, moisture, and rot. Larch and cedar are popular softwood cladding options in the UK, with high-quality larch products featuring few knots.

Oak is a traditional choice for external cladding, but if left untreated, it will develop a silvery, grey color. Other popular timbers for exterior cladding include Blackbutt Burnt Ash, Ironbark, Jarrah, Pacific Teak, Spotted Gum Vacoa, and Spruce. Each option offers strong rot resistance, longevity, and a golden-brown tone, making them suitable for various home styles.

What is the best wood for exterior cladding?

Western Red Cedar is a popular choice for exterior cladding due to its visual appeal and resistance to decay. It is stable and can last for decades without surface treatment. However, it can be dented due to its low density. British-grown cedar is a more affordable option, but it is more knotty than Canadian varieties. Larch cladding is a popular choice for softwood cladding due to its affordability and denser nature. It can be used without coatings or treatments and weathers to an attractive silvery grey over time. Larch can be painted and stained, but it should be checked with a supplier for specific looks.

What wood will last longest outdoors?

Wooden outdoor furniture is generally considered the most durable and rot-resistant type, with hardwoods like ipe and teak being the most durable. These woods can last decades with minimal maintenance, making them ideal for outdoor use. However, it is important to note that any wood outdoors will eventually degrade over time, so it is recommended to use natural oil finishes that can be replenished. Plastic clear coats can eventually yellow and start peeling off, making them unrepairable.

To maintain wooden outdoor furniture, it is essential to clean it with soapy water at the start of spring and apply a couple of coats of your chosen wood stain or paint. Some people let their furniture age naturally, giving it a rich golden brown color, but personally, I prefer a rich golden brown color. Applying an all-weather varnish, such as BEHR Premium Transparent Weatherproofing All-In-One Wood Finish, with a repeat application in Spring every 2-3 years, can help seal up the wood from outdoor elements like UV light, rain, snow, wind, and hail.

Choosing the right wood species reduces the need for regular care, but it does not mean regular care won’t extend the life of furnishings or improve their appearance. All furnishings should be given an occasional cleaning to get rid of dirt and grime, using a dilute solution of Murphy’s oil soap and water. Silicone-based cleaners and polishes are the culprits, so avoid them. Do not soak or flood the furniture while cleaning.

The most severe damage occurs from direct sunlight, melting snow and ice, or standing water. To extend the usefulness of furnishings, they should be protected from direct rain, snow, and sunshine. UV rays break down all woods eventually, and excessive moisture is necessary for fungi, mold, and insects that break down wood. It is best to keep a moisture barrier between wood furniture and the ground, as water will wick up from the soil.

It is best to bring wood furniture indoors for the winter, as melting snow can keep it damp for weeks on end. The freeze/thaw cycle can also damage joints and loosen screws. Do not drape the wood with plastic, as dew can form underneath and cannot evaporate quickly enough for the wood to dry.

Lastly, a water-proof topcoat, such as Le Tonkinois, can extend the life of any furnishings. Jacob Aune’s personal favorite is Le Tonkinois, which is easy to apply, water-proof, and holds up better than most spar varnishes available at home improvement centers.

What is the longest lasting exterior cladding?

Glass is a popular choice for facade cladding due to its durability, low maintenance, and ability to reflect light well. It is also recyclable, making it an environmentally friendly option. Stucco cladding, a mixture of cement, sand, lime, and water, is a low-cost, durable, and long-lasting material that can withstand various weather conditions and requires minimal maintenance. It can be painted over for flexibility in building aesthetics, but it is not the most visually appealing option.

Slate cladding is an elegant and distinguished exterior finish, known for its natural beauty and longevity. Made from natural slate, it offers a unique texture and a range of color variations, adding a sophisticated and timeless charm to buildings. It is highly durable, fire-resistant, and waterproof, providing additional safety and durability benefits.

However, slate cladding is a premium choice due to its significant weight, requiring proper support structures and expert installation. Despite its advantages, slate cladding is not the most visually appealing choice compared to other systems. Overall, the choice between glass, stucco, slate, and slate cladding depends on the specific needs and preferences of the building.

What material is used for external wall cladding?

Wall cladding offers numerous benefits, including protection from elements like climate change, rain, humidity, and sunlight, and increased mechanical sturdiness. It is low maintenance, requiring minimal repair and cleaning. Wall claddings come in various materials, such as wood, brick, vinyl, and terracotta, allowing homeowners to choose the perfect material for their home style. Additionally, exterior wall cladding adds aesthetic value to the structure, enhancing its appearance and boosting its market value.

Bricks are a popular cladding material due to their striking finish, exceptional performance, and structural advantages. They provide energy-efficient warmth in winter and coolness in summer, making them a cost-effective option. Despite its high cost, brick cladding can last longer and requires less maintenance compared to other cladding materials.

What timber to use for external wall?

Timber frame external walls consist of structural studs, sheathing, insulation layers, and an airtight vapor barrier. These elements help manage moisture and maintain the structure’s strength. The use of softwood or hardwood for studs, plywood or OSB for sheathing, and breathable insulation materials like mineral wool ensures better thermal performance, fire safety, and air quality. Breathable membranes and vapour control layers are crucial for moisture control, ensuring the long-term performance of the timber frame structure.

It is recommended to choose a reputable supplier with third-party certifications and positive reviews to ensure compliance with standards and building regulations. Insulated external timber frame walls offer improved insulation performance and low embodied energy compared to masonry walls. Understanding the theory of detailing is essential for adherence to specifications and wall construction. Each layer plays a crucial role in controlling moisture and air movement, protecting the insulation and timber frame structure.

What wood is best for external cladding?

Western red cedar, European larch, European oak, and Douglas fir are popular cladding species due to their resistance to insects, moisture, and rot. However, species like spruce, fir, and pine require treatment with chemicals like boron to prevent decay and increase fire resistance. Softwood cladding, costing £5-8/m2, requires regular painting and staining, requiring three coats of stain when installed.

Despite its cost, softwood is not necessarily the most cost-effective option. The sapwood content of timbers is non-durable, so if present, it requires preservative pre-treatment. Overall, the choice between species depends on the specific needs and budget.

What wood is most weather resistant?

Teak, Cedar, Ipe, Cypress, and Mahogany are weather-resistant woods suitable for outdoor projects due to their ability to withstand harsh sunlight, heavy rainfall, and insects. These woods are a wise investment for those looking to enhance their outdoor spaces. Brazilian Lumber, a specialist in manufacturing and importing high-quality decking solutions, is a go-to source for tropical hardwoods and other construction materials perfect for the great outdoors. The choice of wood depends on its ability to withstand the elements, making it a classic choice among the many options available.

What is the best wood for exterior?

Outdoor furniture is a popular choice for various purposes, including patio sets, porch swings, and tree houses. However, not all wood species are suitable for outdoor use. Some species, like Black Locust and Bois D’Arc, rot slower than others due to their physical barriers called tyloses, which prevent moisture from penetrating the wood and block insects and organisms from penetrating it. When working with wood for outdoor projects, heartwood is recommended over sapwood, as heartwood is the stronger inner-most wood of the tree and often consists of the majority of a stem’s cross-section.

Acacia is a thick, strong hardwood with high oil content, resistant to elements, rotting, and insects. Acacia is abundant and affordable, making it an excellent option for those considering the environmental impact of their furniture. It is durable, resists the elements well, and is often used in boat-building due to its abundance and resistance to water. Once sealed, acacia is a rich, dark, golden brown. However, it should be kept off the grass or ground as it may absorb moisture.

Black Locust is one of the strongest and stiffest domestic woods, competing with Hickory for the title of strongest but offering more stability and rot resistance. It is moderately easy to work with, with a moderate blunting effect on cutting edges and good weathering characteristics. It responds well to both lathe turning and steam bending, glues and finishes well, and can be an affordable wood with great uniform patterns for tables or benches.

In summary, there are many wood species available for outdoor furniture, but only a select few are suitable for outdoor use. Acacia, Black Locust, Cedar, Cypress, Douglas-Fir, Ipe, Redwood, and Teak are some of the most popular and suitable wood species for outdoor furniture projects.

What cladding to avoid?

Cladding materials like ACM, high-pressure laminate (HPL), and metal-based materials like Metal Composite Materials (MCM) have been linked to fire risks. Wood, traditionally used as cladding, can also pose a risk as it increases the opportunity for fire to take hold. While timber is used in some parts of buildings without causing fires, cladding with wood increases the risk. While stone or cement are sometimes used for wall cladding, they pose no greater fire risk than the building’s original materials but can be heavy, making them unsuitable for roof cladding.

What is the most eco friendly exterior cladding?

Composite cladding is considered the most eco-friendly option due to its composition of recycled materials like wood fibres, recycled plastic, bonding agents, and colorants. Wood plastic composite (WPC) cladding is sourced from FSC certified furniture, joinery, and flooring businesses, while recycled HDPE comes from Europe. The plastic is cleaned and turned into small pellets, along with bonding and colour agents, to create a high-quality product.
