What is floor insulation?
A lot of heat in your home is lost through the floor. Cold can easily rise from below, especially in homes with a crawl space. Floor insulation involves fitting insulating material to the underside of the floor or laying it on the ground in the crawl space. This keeps more heat inside, makes the floor feel more comfortable and reduces your heating costs.
The benefits at a glance
A well-insulated floor offers several benefits:
- Greater comfort: no more cold feet and fewer draughts at home.
- Lower energy bills: you need less heating and can often save hundreds of euros a year.
- Healthier indoor environment: floor insulation reduces damp and mould growth in the crawl space.
- Higher property value : better energy performance makes your home more attractive to buyers.
How it works in practice
In most homes, floor insulation is installed from the crawl space. An insulation specialist fixes insulation boards or sprays insulation foam onto the underside of the floor. This keeps the cold out and the warmth in.
Is there no crawl space, or is it too low? The floor can also be insulated from above, for example by fitting insulation boards beneath a new floor covering. This often involves a little more work inside your home, but ultimately provides the same benefit.
Installing floor insulation usually takes just one day. Afterwards, you will notice the difference immediately: the floor feels warmer and your home stays comfortable for longer.

Costs and subsidies
Floor insulation costs an average of 20 to 50 euros per m², depending on the method and material. For a family home, this often amounts to 1.500 to 3.000 euros.
Fortunately, subsidies are available, such as the national ISDE subsidy and, in some cases, municipal schemes as well. These substantially reduce the investment required. The payback period is often between 5 and 7 years, after which you continue to benefit from the savings.
Greenisolatie not only installs your insulation but also helps you apply for a subsidy suited to your situation.
Frequently asked questions
- How much can I save with floor insulation? On average, you can save €200 to €600 per year on your energy bills, depending on the size of your home and your heating habits.
- Is floor insulation suitable for every home? In most cases, yes, provided there is a crawl space with a minimum height of 35 to 50 cm. If there is no crawl space, alternative methods can be used to insulate the floor from above.
- Can floor insulation be combined with underfloor heating? Yes, this is actually recommended. Underfloor heating works more efficiently and uses less energy when the floor is well insulated.
- How long does floor insulation last? The insulation material remains effective for decades and requires virtually no maintenance.
