Cross-Laminated Timber

Cross-Laminated Timber (CLT) is an engineered wood panel product consisting of layers of solid-sawn lumber bonded at 90-degree angles to one another, creating a strong, dimensionally stable structural material that can be used for walls, floors, and roofs in buildings of almost any scale — and has become one of the most significant innovations in sustainable construction of the past three decades. CLT’s structural performance, prefabrication potential, carbon sequestration, and the warmth of its exposed timber surfaces have made it a material of choice for architects and developers seeking alternatives to concrete and steel that reduce the embodied carbon of construction while delivering beautiful, biophilic interior environments. The rise of CLT has transformed the ambition of timber construction, enabling multi-storey and even high-rise mass timber buildings that would previously have been impossible, and it sits at the heart of broader conversations around mass timber construction and sustainable architecture as the building industry responds to the climate emergency.
