The panels provide a continuous energy efficient surface. Read more about changes to thermal elements in the external walls section.

Solid floor insulation cost. The building regulations backstop target u value for ground floors is 0 25w m2k which should be easily achievable with 75mm or 100mm thick rigid insulation boards laid over the surface.
