Reasons for floor insulation

• In the case of an unoccupied attic, floor insulation is cheaper than that insulation of the roof. Even with an insulated one roof It makes sense to insulate the floor if the attic is unused and therefore not heated. This saves you heating costs because the apartment below does not have to be heated as much.
• Impact sound insulation is useful for an occupied attic. You should also consider this type of insulation if the attic is not used as living space, as this may change in the future.
• The floor insulation can be made accessible or not accessible. Even if you have an unused attic, you should opt for resilient insulation, otherwise the attic will also turn out to be a storage room.

Insulation of the floor of the attic

• If you do not want to burden the attic in the future, simply cover the floor with strips of insulation felt or use insulation boards. The insulation is very simple, all you have to do is lay out the entire attic, starting at a corner. Insulation material that is not pressure-resistant can usually be cut with a cutter.
• For floor insulation that should be resilient, insulation boards that are bonded with wood-based panels are ideal. These panels are provided with tongue and groove and must be cut to size with a circular saw. A floor can simply be attached to this floor insulation for a later attic conversion (Laminate, Carpeting).

• You can also cover a non-loadable insulation with wooden floor panels to make it accessible, but the composite systems are clearly superior to this method.
• Since the insulation boards for the floor insulation are not used to beautify the room, you do not have to pay attention to symmetry. Start by laying the insulation panels on one side of the attic and work your way to the other side. A cut may only be necessary for the last panel. Possibly. you also have to cut the panels accordingly for support beams.
• Fleece becomes just like a carpet rolled out. When working with mineral or glass wool, always wear gloves and breathing protection when installing the floor insulation in the attic. It is best to cut fleece with a long, sharp knife.
