Launching Hemspan® Bio Board, The New Wonderwall

A breathable bio-composite, negative carbon, high-performance construction board.

The first production-ready product of its kind to launch in the UK, Bio Board is a 100% natural, formaldehyde-free construction board. The board is fully recyclable and has low embodied energy and carbon binding properties. 

The versatility of Bio Board is one of its many stellar attributes. It is suitable for all interior use, including bathrooms, where it is water-resistant and helps reduce problems with condensation and mould. 

Bio Board helps a home breath. When adding a hemp-lime plaster finish, the result creates healthy and comfortable spaces. It also has an impressive Class B-s1 d0 reaction to fire.

Why Do We Need A Plasterboard Alternative?

Plasterboard is up there with steel and cement as one of the highest generators of greenhouse gases. Once quarried, natural gypsum is dehydrated. The dehydration process involves heating the stone to 150°C to a hemihydrate state, using natural gas and fossil-derived energy. 

Every skip you walk past in the UK seems to have a piece of plasterboard tottering on top.  Despite the ban on plasterboard in mixed landfills, an estimated 300,000 tonnes of the old board end up dumped each year for many reasons, including over-ordering, damaged panels, demolition and refurbishment. Although plasterboard from recycled content is available (and other gypsum materials), it is not biodegradable. In addition, when wet or mixed with decomposing waste,  a chemical reaction forms toxic and corrosive hydrogen sulfide gas.

In contrast, Bio Board is the better, healthier alternative for our environment without compromising on performance or durability.
