Insulating at ground level mainly falls into two categories ... installing upon a Solid Concrete base or incorporated within Suspended Floor

Underfloor heating may form part of the equation.

In suspended floor applications, Phenolic or PIR rigid boards may offer the best solution, and can be used in conjunction with a reflective membrane.

Concrete slabs can benefit from closed cell polystyrene insulation, which can be the most cost effective solution if height is not a major consideration.

Where height is at a premium, reflective foil membrane insulation may form part of a solution

Breather membranes are useful for inhibiting the movement of air and dust.

The brief examples above are indicative of the build-up of various ground floor insulation installations.

When fitting wet system underfloor heating systems above Rigid Board Insulation, it is important to ensure the boards have sufficient strength to hold the system's clips in place while the screed is poured.

Electric underfloor heating systems should not come in contact with a foil-based radiant barrier.
