Coronavirus Free Wall Linings

Safe, Sustainable Fibreboard by Sundeala

Independent tests performed by an ISO 17025 compliant laboratory show that Sundeala FR board is 100% free from viable virus within 5 minutes of infection with human coronavirus.

Sundeala fibreboard has helped Britain face its share of national emergencies. Sundeala board was used in the construction of the very first ‘Nightingale Hospital’ comprised of hundreds of Red Cross Huts behind Netley Hospital during the First World War and, in 2020, it has joined the fight against the Covid-19 pandemic.
Sundeala FR is an inherently fire-resistant fibreboard comprised of recycled paper fibres and natural metallic minerals.
Studies indicate that coronavirus remains viable on porous surfaces and in the presence of some metallic minerals for far shorter periods than hard, smooth surfaces and that the presence of some metallic minerals has a destructive effect on virus particulates.
Sundeala Ltd approached Indoor Biotechnologies – a global immunodiagnostics and biotechnology company, specialising in the development of innovative products and services in the areas of Immunological and Environmental Sciences. Indoor Biotechnologies formulated a methodology designed to robustly test both the surface and fibres of Sundeala FR to determine how long coronavirus was detectable after the point of infection.
The Test
ISO 17025 compliant methodology was used to test multiple separate samples of Sundeala FR board. Tests were done on multiple days and with multiple sets of samples to ensure the testing was scientifically meaningful.

Testing was performed with Human Coronavirus 229E as the closest in behaviour to SARS CoV-2 as well as being the strain proven in previous studies to have the longest persistence on surfaces and be the most difficult to destroy. Virus samples were cultured in cells derived from human lung tissue.
Testing was performed both on the board surface and within the board itself to test the point at which it became safe to touch as well as when it became safe to cut or sand.
The Results
After tests performed at 4 hours and 1 hour showed that no viable virus remained on the board samples, further tests were carried out at 5, 15, and 30-minute time points.
The results were conclusive: within 5 minutes of infection with a large viral load, there was zero viable virus persisting either on the surface or within the Sundeala FR board itself.
The Impact
As the economy struggles for recovery amidst local lockdowns, the construction industry is being called on to navigate the waters of the ‘new normal’ with a new set of safety considerations around reducing the transmission of coronavirus.
A new study from Australia shows that coronavirus can persist on some non-porous surfaces, such as glass and stainless steel, for as long as 28 days, raising serious concern about high-touch surfaces such as metal door plates.
The efficacy of Sundeala FR against potential viral transmission is game changing for public health where Sundeala FR is being used throughout schools, universities and offices as door push-plates, social distancing screens and wall cladding in high-footfall circulation spaces. It also a welcome antidote to the ‘Plastic Pandemic’ that has seen the use of imported virgin plastic escalate on a previously unimaginable scale during Covid-19. Sundeala FR is manufactured in the UK from 100% UK sourced ‘waste’ cellulose fibres that would otherwise end up in landfill.
The need for fast, disruption free and, above all, safe construction has never been more pressing. Sundeala FR is manufactured in the UK and can be delivered on a ‘just in time’ basis to be installed during offsite fabrication, either as 2400 x 1200mm sheets or cut to size as required.
Benefits:
•  100% free from human coronavirus within 5 minutes of infection both on the surface and inside the board itself.
• Fully circular product manufactured from recycled waste materials and able to be endlessly re-manufactured into new board at the end of life.
•  Made from natural cellulose fibres and metallic minerals.
•  Wet-process fibreboard utilising hydrocarbon bonding for strength. Zero use of chemical binders or VOCs in the production process.
•  BS EN 13501-1 Class B Fire Rated: suitable for use as a wall lining in circulation spaces, corridors, and high-risk rooms such as science labs and kitchens.
• 25-year surface warranty
