Ufloor – A non-disruptive underfloor insulation technology


After successful roll-out of mass energy-efficiency schemes over the last few years (e.g. ECO, CERT, Decent Homes) the government is soon launching the next ‘Help-to-Heat’ support scheme, focusing on fuel poor homes.

Easy-to-treat, low cost retrofit measures, such as loft or cavity wall insulation, has already been widely implemented. However, the UK is abundant of older, ‘hard-to-treat’ homes where improving the fabric efficiency is often more expensive.

We identified an untapped potential: floors are responsible for up to 20-25%[1] of the heat loss, and more than six million homes in the UK were built with suspended timber ground floor. However, due to the high costs and high disruption of traditional methods, floor insulation has not been adopted widely.

To address these challenges, we have develeoped an innovative, low-cost, non-disruptive insulation technology, Ufloor that: 

i)                    eliminates structural disruption;

ii)                   cuts costs by speeding up the installation process;

iii)                 makes underfloor insulation accessible to the mass market. 


The project has benefitted from the support of the Horizon 2020 SME Instrument Phase I. programme and the technology is currently under further development.
