Mould and time rot do not develop as fast in changing circumstances, as present in ground voids, and air flow ensures unstable situations. Water and radiator pipes within the void also needs to be insulated, with no gaps in the insulation sleeves as this will turn out to be a surface for condensation, contributing to moisture issues within the void.

• For homes without basements and those with unheated cellars, adding insulation can bring heating prices down.
• There are approximately 6.6 million dwellings in the UK built earlier than 1919, predominantly constructed with suspended timber floor floors whose thermal performance has not been extensively investigated.
• If the void under the ground just isn't sufficiently ventilated, putting in an hermetic layer between the floor and the ground will trap moisture and result in damp and the potential decay of the timbers.
