What is roof insulation?
Roof insulation involves applying insulating material to the interior side of the roof to prevent heat loss. We do this for both pitched and flat roofs.
The insulation material generally consists of:
- Glass wool
- Rock wool
- PUR foam
- PIF thermal cushions
This material ensures that heat stays inside during winter and keeps the heat out during summer. As a result, you significantly reduce your home’s energy consumption, which you will see reflected in your energy bill.
At Greenisolatie, we use only the best materials and techniques to ensure your roof is optimally insulated. This includes carefully placing the insulation material between the roof beams or against the roof decking, depending on the structure of your roof.
A well-insulated roof can prevent up to 25% of heat loss!
Advantages of roof insulation by Greenisolatie

Save up to 25% per year on heating costs:
With roof insulation, you can save up to 25% annually on your heating costs. By applying insulating material, the heat stays better inside your home, meaning your heating system doesn’t have to work as hard. This automatically results in a lower energy bill. The initial investment in roof insulation quickly pays off through the monthly savings on your energy expenses.

Improved living comfort:
Roof insulation acts like a blanket for your home, keeping the cold out in winter and the heat out in summer. This creates a more consistent temperature inside, regardless of how hot or cold it is outside. You will quickly notice that your home is heated more evenly and that there are no cold drafts blowing through the house.

Sustainable and environmentally friendly
Reduce your CO2 emissions and contribute to a better environment by optimizing your energy consumption. The less energy you need, the less you emit.

Increased property value
Good insulation is an investment in your home that increases its market value and makes your property more attractive to future buyers.

Glass woolRock woolPUR foamPIF thermal cushions
For roof insulation, specifically HFO spray and PIF foil are excellent, modern choices:
HFO spray
HFO spray is an innovative insulation solution that provides high-quality thermal properties. It is sprayed onto the roof surface, filling all gaps and seams, creating a seamless insulation layer. This results in an efficient heat barrier and significantly reduces energy loss.
PIF thermal cushions
PIF foil is a reflective insulation foil that is easy to install and works by reflecting heat back into the interior space. It is lightweight, very durable, and has strong thermal properties.
