What is the payback period for insulation?
Insulation is not only good for the environment and your comfort at home, but also a smart financial investment. Lower energy bills mean you recoup the cost of insulation over time. The payback period varies by insulation measure, but is often surprisingly short.
The benefits of investing in insulation
Insulation offers more benefits than you might think. The main advantages at a glance:
- Lower energy bills: you use less gas or electricity.
- Short payback period: costs are often recovered within a few years.
- Higher property value: a better energy label makes your home more attractive.
- Sustainable living: lower CO₂ emissions and better for the environment.
How is the payback period for insulation calculated?
The payback period for insulation depends on:
- The investment: how much the insulation measure costs.
- The savings: how much less you pay for energy each year.
- Available subsidies: schemes such as ISDE or municipal subsidies significantly reduce your investment.
Simply put: divide the investment by the annual savings. The resulting number of years is the payback period.
Average payback periods for each insulation measure
The payback period for insulation varies by type of measure. On average, you can expect:
- Cavity wall insulation : often 3 to 5 years.
- Floor insulation : usually 5 to 7 years.
- Roof insulation: approximately 7 to 10 years.
- HR++ glazing : an average of 7 to 9 years.
After this period, you enjoy the full savings and a lasting improvement in your home's comfort.
Frequently asked questions about the payback period for insulation
Is the payback period always the same? No, it varies depending on the home, energy prices and the chosen insulation method.
Does a subsidy affect the payback period? Yes, a subsidy reduces your investment, making the payback period significantly shorter.
Does insulation last as long as its payback period? Yes, insulation often lasts for several decades. You therefore continue to benefit long after you have recouped your investment.
