The conventional wisdom around insulating existing floors in your home is that it is problematic. Full Stop. Why? Well, because without going ahead and lifting a solid floor, we are often advised that it is difficult to introduce any permanent thermal insulation. Once a floor is in place, it is like an immovable object. However there are floor insulation solutions available.
Traditionally solid floors will often feel cold and a little damp, as tiles, bricks or flags could be laid directly in contact with the ground beneath. Concrete floors present another set of problems. Even if the floor includes a damp proof membrane, it may not be well insulated. And where there is a DPM and no sign of moisture, the advice is typically that you can go ahead and lay a wooden floor or some sort of flooring with a thermal underlay.
A lack of awareness of the options available means that householders often settle for a solution that is far from ideal. And they continue to lose heat through their floor.
Heat Loss Through Floors
When you think about heat loss, most people straight away look at the usual subjects. Draughty windows and doors, but it is a fact that heat lost through a solid floor can cost you money and drastically reduce the energy efficiency of your home.
Heat loss through the floor is particularly a problem in older homes. Many older buildings will have ground floors made from either uninsulated or poorly insulated solid concrete. It relates to the original construction of the building when builders were less aware of the potential for heat loss.
It wasn’t until the 1930s that concrete floors became relatively common. Prior to that ground floors tended to be basic slabs or tiles laid onto the ground. The Victorians used suspected timbers in most rooms, and for upper stories, floors featured timber joists. Modern suspended concrete floors didn’t appear until the 1990s. Also, main older homes had their floors dug up and replaced with concrete.
The problem that you face if you have a concrete floor is that excavating the surface isn’t an option for obvious practical reasons. The other problem is that a layer of insulation that is too deep will cause problems with doors closing and the level of adjacent floors.
