ISDE subsidy for your windows
We help you obtain a Dutch government subsidy for energy-saving measures on projects in the Netherlands
We handle the paperwork, you benefit from the subsidy
Through the ISDE (Investeringssubsidie Duurzame Energie en Energiebesparing) — a Dutch government subsidy for sustainable energy and energy-saving investments — you can receive a subsidy for replacing window frames and glass. KozijnenSet helps you with every step of the application process.
- Complete documentation — we provide all invoices, technical specifications and parameters required by RVO (Netherlands Enterprise Agency)
- Subsidy reporting code — you receive from us the required reporting code for the applied glass and insulation solutions
- Personal guidance — we guide you step by step through the subsidy application with RVO
- Higher success rate — thanks to a complete dossier with all required codes and documents
🏠 ISDE subsidy in brief
The ISDE is a subsidy from the Netherlands Enterprise Agency (RVO) available to homeowners in the Netherlands who invest in energy-saving measures, such as HR++ or triple glazing and insulating window frames.
Potential subsidy per home
The exact amount depends on the type of measure, the surface area and the number of measures. We calculate for you what you can expect.
About KozijnenSet
Craftsmanship, quality and personal contact are our top priorities
The owner on every project
At KozijnenSet you always have direct contact with the owner — who also personally supervises and inspects every installation. No intermediaries, no miscommunication and no compromises on quality.
We work exclusively with the best profiles on the market: Schüco, Salamander, Aluplast and Gealan. With the widest renovation profile in the stiffest version and foam-filled variants for maximum insulation. And with dozens of colours — where others offer only five or six.
Our finishing is top-level: interior with decorative plaster mouldings and acrylic sealant, exterior with Keralit and Trespa. And if additional work is needed — such as adjusting a driveway so your doors open properly — we take care of that too.
