172 Featured products The following products have received third-party praise for their sustainability performance and collectively provide good examples of how manufacturers are seeking to achieve gains against various environmental metrics. Until there is a common industry set of requirements for sustainable products, designers and specifiers will have to judge for themselves whether these and other products meet their own environmental standards. Bio-Dek Butterr Ultra Lightweight Underlayment is a bio-renewable/bio-infused, three-component, 100 per cent solids epoxy ultra-lightweight underlay material designed with performance characteristics which include low odour, flexibility, excellent adhesion, hydrophobicity and low temperature cure. The resin structure design is based on cashew nutshell liquid and the aggregate structure is based on recycled glass, which creates a high-performance system. This levelling material will provide a seamless, waterproof barrier designed to work in wet spaces, galleys, passageways and all other areas where deck irregularities need to be removed from a deck plate. Material can be applied from a feather edge to three inches in a single application. The structure is designed to receive all top-coat systems. Bolideck, Bolidt A synthetic decking system is an unlikely product to feature in a sustainability report but Bolidt has earned a reputation for R&D advances that continue to improve the environmental performance of its products. In the first instance, synthetic decking has become the default choice for passenger ships, replacing teak – a precious tropical hardwood. Bolideck is light and its inherent properties mean that it can be applied thinly (base layer of 10-15mm and top layer of 5mm depending on deck levelling and soundproofing requirements) to minimise material use. Bolideck is light, delivering fuel savings, and durable, with an expected life of over 15 years. It can also be refreshed and repaired during its life to maintain high aesthetic standards. At the end of its life it can be lifted cleanly off the deck, having protected the steel beneath it, then ground down and added to the base levelling layer of a new project. The company has recently released bio-based cleaning products that contain bacteria which will continue to clean the deck even after it has been rinsed. Looking to the future, Bolidt is currently testing a bio-based hardener and is working on the logistics of offering a service to grind old decking material for the levelling layer on site during a refurbishment project.
