Dankjewel mannen!Posted on A.2025-12-10Trustindex verifies that the original source of the review is Google. Heel vriendelijk geholpen. Had een formulier ingevuld en er is vrij snel contact met mij opgenomen, hierin heb ik mijn wensen verteld en hebben we een vervolgafspraak gemaakt. Ik wilde graag mn muren opnieuw laten isoleren en vloer ook, ze hebben mijn muur en vloer bekeken en ze vertelde dat de vloer al netjes geïsoleerd is. Super fijn want dan weet ik dat het niet om geldklopperij gaat. Daarna al gauw volgde de afspraken van mijn muur en wauw wat netjes en snel geregeld.Posted on Alisia2025-12-02Trustindex verifies that the original source of the review is Google.

Cavity wall insulation
Our cavity wall insulation increases the thermal efficiency of your home by filling the space between the inner and outer walls with insulation material. This prevents heat loss and specific “cold bridges.” In other words, it creates an even indoor temperature and lowers your heating costs. The process is quick and has minimal impact on your daily life, making your home comfortable and energy-efficient in no time.
For maximum results, cavity wall insulation is often combined with roof insulation or floor insulation. In many cases, you may also be eligible for the ISDE insulation subsidy, which makes the investment even more attractive.
Floor insulation
Floor insulation ensures that heat stays better inside the home, so you need to use the heating less often. This creates a more comfortable indoor climate, with less draft and prevents cold feet. Moreover, floor insulation contributes to a healthier living environment by reducing moisture problems in the crawl space. Insulating the floor is an efficient way to save energy and increase living comfort. Our experts provide professional and quick installation, so you can immediately benefit from the advantages of a well-insulated floor. For a reliable and experienced floor insulation company, you have come to the right place with us.
For optimal insulation results, floor insulation is often combined with cavity wall insulation or roof insulation. In addition, floor insulation can in many cases be included under the ISDE insulation subsidy, depending on the chosen measure.
What is roof insulation?
Roof insulation involves applying insulation material to the inside 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
Roof insulation is often combined with cavity wall insulation or floor insulation to reduce heat loss throughout the entire home. In many cases, this measure can be included under the ISDE insulation subsidy.
What does HR++ glass entail?
HR++ glass is insulating double glazing that helps retain heat inside and keep cold air out. This results in a more comfortable indoor climate and lower energy consumption in the home.
- Lower heating costs
- More comfortable living environment in the home
- The sound from the street is less noticeable
HR++ glass is often combined with cavity wall insulation or roof insulation for optimal insulation performance. In many cases, HR++ glass can also be included under the ISDE insulation subsidy.
Subsidy
This subsidy covers part of the costs for cavity wall insulation, floor insulation, and roof insulation.
To qualify, you only need to carry out one energy-saving measure. The subsidy amounts vary depending on the insulation measure and the surface area you insulate. Additionally, you may also benefit from local subsidies or loans with favorable conditions.
