I have an old 60 year old house that has a raised timber ground floor above a concrete floor. The void is aprox 3 ft.
Traditionally you would fill this with hardcore and then a layer of concrete, to form a new floor.
But my wife insisted on getting laminate flooring ontop of the T&G and beams, and I do not want to lift that.
Is there any other way of insulating the floor void. I have thought about injecting cavity wall insulation.
Any ideas or suggestions that the regulations people would accept ???
