BastWave™ is a sustainable panel material developed by Margent Farm in the UK, engineered from a high proportion of natural hemp fibre bound with plant-based bio-resin. The corrugated sheets deliver structural rigidity and versatility, offering a low-carbon alternative to traditional cladding materials such as steel, PVC, bitumen and cement-fibre boards.

Crafted with a naturally high cellulose content – typically around 60–70 % – the panels harness hemp’s inherent strength and carbon-sequestering properties, making them an effective solution for exterior rainscreens, interior wall linings and bespoke design applications. BastWave™ can be used in similar ways to conventional corrugated systems while retaining a distinct bio-based character and environmental value.

The nature of the material means it will weather and light-tone over time when exposed to direct UV, akin to timber, unless specifically coated for UV protection, and it can be customised with darker finishes on request.

BastWave™ panels illustrate a broader regenerative approach to material design – capturing embodied carbon in hemp biomass and integrating agricultural by-products into the material system, while supporting low-impact, circular construction practices.
