Subsidy for insulating glass and frames 2027 (ISDE, Netherlands)

Q: How much subsidy do I get for insulating glass in 2027?

Through the ISDE you get € 30 per m² for HR++ glass and € 55 per m² for triple or vacuum glass in new frames in 2027. If you carry out another insulation measure within 24 months or have a heat pump installed, the amount is doubled. A minimum of 3 m² and a maximum of 45 m² of glass applies.

Q: Do I get the triple glazing amount if I don't replace my frames?

No. For the triple or vacuum glass amount you must also have new frames installed. If you only replace the glass, you get the HR++ amount.

Q: What is a registration code?

A registration code is an RVO product code for glass that qualifies for a subsidy. You can find it in RVO's Meldcodelijst Hoogrendementsglas. We put the code on your invoice.

How much subsidy do you get per m²?

The amounts apply per square metre you replace. If you carry out another insulation measure within 24 months or have a heat pump installed, they are doubled.

Amounts per m² for one measure, according to RVO for 2027. Check the current amounts on rvo.nl before you apply.

Worked example

15 m² of triple glazing in new frames

You receive € 825 in subsidy (15 × € 55).

Do you also insulate your roof or floor within two years, or have a heat pump installed? Then that becomes € 1,650.

With HR++ glass you receive € 450 for the same 15 m², or € 900 doubled.

An estimate based on the RVO amounts for 2027, for glass only. Insulating doors and panels give additional subsidy. What you actually receive is decided by RVO after your application.

Budget

Is there still money available?

RVO sets a budget for the ISDE every year. Once it is used up, you can no longer apply that year. So do not wait too long to apply once the work is finished.

You can see how much budget is left on RVO's page ISDE: stand van zaken budget. It is updated regularly.

Frequently asked questions

Questions about subsidies for glass

Do I get the triple glazing amount if I don't replace my frames?

No. For € 55 per m² you must also have new frames installed. If you only replace the glass, you get the HR++ amount: € 30 per m².

Can I apply for the subsidy before the work is finished?

No. You first have the glass installed and pay the invoice. Then you apply, no later than 24 months after installation.

How does the doubling work?

Do you carry out another insulation measure within 24 months, such as roof, floor, facade or cavity wall insulation, or have a heat pump, solar water heater or heat network connection installed? Then the subsidy for your insulation is doubled. A ventilation system alone does not count for this.

What is a registration code?

A product code from RVO for glass that qualifies for a subsidy. You can find it in the Meldcodelijst Hoogrendementsglas on rvo.nl. We put the code on your invoice so you don't have to look it up yourself.

Is there also a subsidy for a new front door or frame panels?

Yes, if you have HR++, triple or vacuum glass installed at the same time. An insulating door must have a Ud value of at most 1.5, insulating panels a U value of at most 1.2. The better the insulation, the higher the amount. The current amounts are on rvo.nl.

Can I apply for a glass subsidy twice?

Yes. You may apply twice for glass, as long as the second application falls within 24 months of the first glass installation. Handy if you have the front and back done at different times.

I own a listed building. Can I also get a subsidy?

Yes, adjusted conditions apply to listed buildings. Glass for secondary glazing in a listed building may have an insulation value of up to 5.8. See RVO's page for listed buildings for details, or ask us when we measure up.

Does a new sliding door or folding door count?

Yes, if it replaces an existing sliding door or existing windows. The glass then counts as insulating glass. If it goes where there used to be a solid wall, it does not count.
