How cross laminated timber is paving a sustainable path to Australia’s architectural future

Architecture practices across Australia are increasingly embracing sustainable solutions, and one material is leading this charge – Cross Laminated Timber (CLT). Known for its strength, sustainability, and versatility, CLT offers a revolutionary approach to modern construction that is keenly resonating within the architectural community.

What is cross laminated timber?

Commonly referred to as CLT, cross laminated timber consists of multi-layer solid wood panels, typically made from plantation pine. These panels are engineered by stacking wooden layers crosswise and bonding them together, resulting in an exceptionally strong, versatile, and structurally sound material. Knauf Gypsum has partnered with XLAM to develop lightweight cross laminated timber systems that use established plasterboard construction methods. 

The benefits of CLT in construction

In the realm of construction, CLT stands out for several crucial advantages. First, its environmental viability is evident: CLT panels store more carbon than they emit during manufacturing, establishing them as carbon positive materials – a significant step towards reducing the environmental impact of construction projects.

Australian architects are recognising CLT's potential not only for its ecological benefits but also for its practicality. With a strength-to-weight ratio approximately 20% higher than steel and 4-5 times higher than non-reinforced concrete, CLT buildings are robust and well-suited to withstand Australia’s diverse weather conditions, including strong winds and earthquakes.

Moreover, CLT facilitates faster construction times, with XLAM delivering a remarkable 20% reduction in superstructure build times compared to traditional concrete and steel methodologies. Prefabricated sections manufactured with precision empower architects to streamline project timelines without compromising on quality or design.

Advanced performance in design

What makes CLT particularly appealing to architects is its multifaceted performance capabilities. From acoustics to fire resistance, CLT adheres to stringent standards set by the National Construction Code. Knauf CLT systems are backed by extensive testing and certifications for fire protection, ensuring suitability in diverse building environments up to 25 metres in height.

Furthermore, CLT's excellent thermal and acoustic performance, achieved using Knauf Insulation glasswool in cavities, provides comprehensive solutions that align with project specifications without sacrificing aesthetic or structural integrity.

Embracing biophilic design

An intriguing aspect of CLT is its ability to harmoniously integrate with biophilic design principles that foster connections between people and nature. With an affinity for timber and the innate human desire for natural elements, CLT structures promote healthier environments while providing visually appealing, comfortable spaces that connect the indoor and outdoor realms.

Building the future with CLT

As sustainability in architecture becomes a standard practice, the adoption of materials such as cross laminated timber is pivotal. By choosing Knauf CLT systems, architects not only contribute to eco-friendly construction practices but also innovate designs that balance function, aesthetics, and nature.
