An underfloor heating floor construction typically used to retrofit underfloor heating in in domestic prop-erties.
It is designed to be retrofitted to existing floors, making it suitable for both new builds and retrofit where an increase in floor height can be accommodated
Offering a higher heat output than the foil faced Expanded Polystyrene (EPS), this makes this floor construction more suitable when using heat sources that are sensitive to flow temperature, such as ground and air sourced heat pumps. Careful calculation should still be done to ensure suitability.
