Insulate wooden floors - increase comfort

If a wooden floor is to be subsequently insulated, this raises different problems depending on the construction. So that you don't get cold feet any more, here are some solutions for an uninsulated wooden floor. One solution, however, involves covering your wooden floor with new flooring, or taking it up and laying it back with new construction.

Problem definition

In some older houses are simply built on the ground floor wooden floorboards over an air layer. Underneath is simply the soil or a cellar. If at least a creeper is available, you can easily run a subsequent insulation from below. However, if there is no way to reach the bottom from below?. In addition, they must then check whether the undertaking of the wooden floor has not been attacked by moisture and rot.

Heightening height

Depending on whether or from below or from above the wooden floor subsequently insensively, you often have a problem with a low construction height. Often only an insulation thickness of ten centimeters, for example, can be inserted between the beams on which the wooden floor rests. In order to ensure effective insulation, special high-density insulation materials must usually be used.

Important points when choosing insulation:

  • Compressive strength
  • Resilience
  • Fire resistance
  • particularly high thermal insulation properties
  • high sound insulation
  • moisture resistant

Insulating the first floor

If you can reach the wooden floor from below, the insulation is easy, all you have to do is install a vapor barrier under the wooden floor and insert the chosen insulation material between the joists. An additional vapor barrier should then be attached towards the bottom. If you attach an air-impermeable film here, your wood can no longer breathe and would eventually start to rot.

Hide wooden floor

If there is no way to get to the substructure of the wooden floor, or if there is none anyway, then all you have to do is lay out the insulation on the floor. Note, however, that the height of the room will shrink as a result of the measure. You will also need to use special vapor barriers so that the wood does not suffer from the new insulation.

Insulate the false ceiling with a wooden floor

In many single-family houses, the ceiling between the floors is not insulated. This not only results in a large loss of heat, as the heat now pulls upwards. If you don't want to heat the attic or unused rooms on the first floor, you have to insulate the false ceiling.

Here we show an overview of the individual steps involved in insulating false ceilings. This insulation is carried out from above by picking up the wooden floor. If you want to insulate from below, the plasterboard ceiling is usually in the way. Replacing these is often a lot more work.

  • Pick up wooden floor
  • Insert vapor barrier
  • Introduce insulation
  • If necessary, insert an additional vapor barrier or fleece
  • Lay out the wooden floor again
