Wave-layered timber, Developed by: Aalto Haitek
Many wooden construction materials rely on adhesives to keep them together, but a new system designed by Aalto Haitek in Finland is out to change that. Wave-layered timber (WLT) is a glue-free building system that utilises the strength of the wave shape to lock together self-tightening components. The system has flexibility and simplicity at its heart, and creates extremely strong structures that can be built rapidly without the need for adhesives, nails, chemicals or toxins, opening new opportunities for architects to flex their creative muscles with wood in construction. The goal is to scale the technology to a global market, with licencing soon available.
A pilot project, Pinewood B&B, is underway in Mäntsälä in Finland, where architects and owners are realising the full benefits of the WLT system. WLT’s simplicity keeps the construction costs low, whilst its design allows for natural heating and cooling systems that reduce the building’s energy consumption. The modular construction allows components to be dis- and reassembled multiple times, for reuse in different contexts, enhancing the lifespan of the products. In this pilot, the WLT is being paired with clay and bio-based insulation for an entirely natural construction, and the project is partnering with an academic research project into WLT.
