CLT offers a multitude of benefits in regards to the performance and sustainability of the environment. As it is available readily manufactured from sustainably managed forests as well as its long-term storage of the carbon absorbed by the sustainably grown trees, the production of CLT results in substantially fewer greenhouse gas emissions than many non-wood materials. Due to their engineered manner panels are manufactured to exact measurements and requirements which results is less wastage and a simplified building process.
Upon the demolition of a CLT based construction project, leftover wood is able to be utilised or recycled for a magnitude of other uses due to its wood nature. The CLT contains biomass and its panels and any other individual elements are recyclable, they are able to be sent back to the manufacturer for reuse and recycling. While items such as sawdust and wood-scraps are not as easily reused or recycled, they can be converted to energy through burning. Alternatively they can be made into chips or compressed into pallets that can be shipped to companies where they’re burned in a similar fashion to coal as a source of energy.
Cross Laminated Timber is incredibly strong relative to its weight, it weighs just one fifth of reinforced concrete. In addition to CLT projects being incredibly easy to construct due to their simplicity along with accurate measures, they can also be easily deconstructed and demolished within a considerably small amount of time. Post demolition of CLT allows for the reuse and recycling of leftovers. Due to the lightweight structure of CLT, construction and demolition is significantly faster than that of other materials. This leads to reduced labour cots at both stages.
The use of Cross Laminated Timber on site results in little to no job site waste in all aspects! Due to the fact that CLT is an engineered prefabricated product, it produces very little onsite waste and any waste that is produced can be reused of recycled for other purposes. Waste made on the construction site will be fed back to the manufacturer for use as carbon neutral energy. Due to less offsite designing work and less cleaning of the wastage there is a reduction in labour hours and disruption to neighbours is kept to a satisfying minimum.
CLT is made though a multi-layer construction system which is made completely of solid wood. The result of bonding the transverse layers together ensures that the risk of swelling, shrinking and warping of the wood is reduced to a negligible level. CLT in construction comfortably fulfils the standards and requirements of modern building material. The characteristics of the CLT structure allows for openings, shapes and modifications of a vast variety of different shapes and forms without the compromise of a buildings structural integrity. The design allows for fewer elements to create the same structures that are both intricate and unique that can be achieved by other traditional materials. Engineered wood products have defined and standardised structural properties which makes the strength and thickness of the panels both reliable and measurable. With increased advancements in technology and adhesives, CLT offers a cost effective option for almost any design and structural application while maintaining a strong and reliable foundation.
CLT offers a multitude of benefits in regards to the performance of the environment. Sustainably managed forests allow for carbon neutrality and acts as a repository of carbon by converting CO2 into biomass through the process of photosynthesis. In comparison to concrete and steel, CLT and wood in general out performs in both matters. Wood and wood products such as CLT produce less greenhouse gasses, require smaller amounts of water, energy and fossil fuels than both concrete and steel. CLT has a lower embodied energy per weight than many other building materials and ‘negative’ carbon footprint, a benefit to the individual and community as a whole.
