How thick are the layers in the floor?
Since both the loosefill layer and the slab have insulating properties, their thicknesses are dependant upon certain variables required to calculate U values. Completion of the online calculation form will allow us to work out the depths required for your specific building. Although this may not seem important, it obviously has an impact on the warmth and comfort of the room and the long-term energy consumption/running costs.
Minimum depths for the system to work are 120mm of Glapor recycled foam glass aggregate and 100mm slab.
