Popularised in Europe, Cross Laminated Timber (CLT) is being touted as a promising option for sustainable, versatile building. The material consists of planks of sawn, glued, and layered wood, joined at perpendicular angles to obtain structural rigidity in both directions. The panel has great tensile and compressive strength.

The panels can function as walls, floors, furniture, ceilings, and roofs; CLT’s thickness and length can be adaptable to the demands of each project. CLT panels are cut in their production, already foreseeing the joints required by the design. A�Construction on site lasts only a few days due to a quick drying process. The structure requires no cladding in drier regions, reducing cost. A finish of transparent waterproofing makes the fibres of the wood evident. Factors such as shorter construction time, greater quality control, and low-wastage can balance out higher material costs.

Made from reforested wood, it doesn’t require the burning of fossil fuels during its production. It has been used for infrastructure and support in large construction sites, and its potential for small constructions has been noted because of its interesting appearance and structural strength. It has recently started being used in larger projects as well, as a�?The Treea��, in Norway, became the first 14 storey CLT building in 2015. The 300-meter-tall a�?Toothpicka�� in London is also in the pipeline.
