An Architect’s Concerns with Timber Properties: Balancing Aesthetics and Functionality
While timber has been a staple in architecture for centuries due to its renewable nature and versatility, this isn’t to say that it’s without its downfalls. From commercial buildings to residential homes, timber boasts a connection to nature, warmth, and beauty, each of which makes it a popular material choice. Despite this, architects rightfully have some concerns when working with timber, even in spite of its aesthetic appeal. This is because there’s a complex landscape of factors to consider when it comes to ensuring the visual allure and structural integrity of the design. To that end, detailed below are some of the most common concerns of architects when working with timber.
Commercial Timber Treatment
Firstly, since wood is a natural material, it can be the ideal environment for pests to breed and live. As a result, commercial timber treatment is often required to guarantee the durability of timber buildings. This type of treatment enhances timber’s resistance to moisture, fungi, and insects and is achieved via chemical treatments. These chemical treatments typically involve pressure impregnation with preservatives, which is designed to extend the lifespan of timber in even the most challenging of environments. Common preservatives include creosote, alkaline copper quaternary (AQC), and chromated copper arsenate (CCA), which all protect timber from insects and decay.
Challenges and Considerations
Although commercial timber treatment has its benefits, this isn’t to say that it’s without its challenges. For instance, some treatments may leach chemicals into the environment over time, which can raise concerns about their environmental impact. Therefore, it’s important for architects to tread the balance between treating timber to the point longevity is assured and looking after the building’s occupants and its environment.
Sustainability and Environmental Impact
Environmental awareness is higher than it has ever been before, meaning sustainability is one of the main concerns when it comes to timber construction. As a result, architects often educate themselves on whether their chosen timber aligns with sustainable forestry practices. In order to mitigate the impact of deforestation, they can use certified timber from well-managed forests. This also encourages the growth of healthy and diverse ecosystems, meaning many architects choose to incorporate sustainable timber into their designs. As a result, carbon emissions are reduced, and a greener construction industry is promoted.
Durability and Longevity
Regardless of the building and the material, longevity and durability are of the utmost importance. Therefore, this is also a primary concern of timber properties. This means that architects are required to assess the environment in which the building will be placed. For instance, some locations are particularly exposed to moisture, insects, and other external elements that can impact the lifespan of timber considerably. Some wood actually boasts a natural resistance to decay, including redwood and cedar; however, as previously mentioned, some species of timber require additional treatment.
Strength and Load-Bearing Capacity
The same can be said for strength and load-bearing capacity as durability and longevity in the sense that it’s of the utmost importance. For instance, different species of timber have varying strengths, meaning architects are required to select the best type depending on the intended application. For instance, pine and other softwoods are typically used in framing because of their strength-to-weight ratio. Meanwhile, oak and other hardwoods are robust, meaning they’re able to withstand heavy loads.
All in all, architects have a massive responsibility to ensure that buildings are safe for use. Regardless of the material used, architects have a number of considerations that they need to sift through when it comes to creating liveable spaces. The material is just half the battle.
