Solid floors are insulated using rigid insulation foam which can be fitted either above or below the concrete.

Most modern homes have a solid floor for example. When uninsulated they will both have a u value of between 0 45w m 2 k and 0 70w m 2 k but this depends on the geometry of the floor and the amount of thermal bridging. If the concrete is above the insulation it can sometimes store heat during the day which helps keep the room warm at night. If the insulation is above the concrete the room will heat up more quickly in the morning.

These can be fitted with new rigid concrete solid flooring or fixed plasterboard that should help fill any cracks or gaps formed over time and improve the overlay s insulating properties.
