List of Measures for the Local Insulation Initiative Grant Program

Version 1: For Owner-Occupied Homes

(Last updated: August 2026)

1	Energy-saving measure	Minimum number of^{square meters}	Minimum Rd value or maximum U-value*	Comments
2	Cavity wall insulation	10^m²	Rd value ≥ 1.1^m² K/W
3	Façade insulation	10^m²	Rd value ≥ 3.5^m² K/W	This applies to the interior or exterior of the facade. You will not receive a grant for interior walls or partition walls.
4	Roof insulation	20^m²	Rd value ≥ 3.5^m² K/W
5	Attic/Loft Floor Insulation	20^m²	Rd value ≥ 3.5^m² K/W
6	Floor Insulation	20^m²	Rd value ≥ 3.5^m² K/W
7	Floor Insulation	20^m²	Rd or Rbf ≥ 3.5 m²K/W
8	HR++ glass	3^m²	U-value ≤ 1.2 W/m²K
9	Triple-pane glass		U-value ≤ 0.7 W/m²K
10	Vacuum Glass		U-value ≤ 0.7 W/m²K
11	Insulation panel		U-value ≤ 1.5 W/m²K
12	Insulated door		U-value ≤ 1.2 W/m²K

The requirements for surface area and insulation values are specified in the “ Requirements ” (Guidelines for Energy-Efficient Housing) for the ISDE subsidy. The requirements for the ISDE subsidy are therefore the guiding principleshttps://www.rvo.nl/subsidies-financiering/isde/woningeigenaren/isolatiemaatregelen#Requirements-insulation

You can receive a grant to cover all costs necessary for implementing the energy-saving measure(s). For example, insulation materials, labor costs for the contractor, and finishing materials such as drywall and paint/plaster.

*The higher the Rd value, the better the insulation. The lower the U-value, the better the insulation.

Version 2: For owner-occupied homes that are designated historic landmarks

1	Energy-saving measures	Minimum number of^{square meters}	Minimum Rd value or maximum U-value*	Comments
2	Cavity wall insulation	10^m²	Rd value ≥ 1.1^m² K/W
3	Façade insulation	10^m²	Rd value ≥ 2.5^m² K/W
4	Roof insulation	20^m²	Rd value ≥ 2.5^m² K/W
5	Attic/loft Floor Insulation	20^m²	Rd value ≥ 2.5^m² K/W
6	Floor Insulation	20^m²	Rd value ≥ 3.5^m² K/W
7	Floor Insulation	20^m²	Rd value ≥ 3.5^m² K/W
8	Front or rear glazing	3^m²	U-value of glass ≤ 3.0^W/m²Kif the measure is implemented by January 1, 2026 U-value of glass ≤ 5.8^W/m²Kif the measure is implemented as of January 1, 2026	May be used as a replacement for or addition to glass (window) surfaces, frame panels, or doors
9	Insulated window frame panels		Panel U-value ≤ 2.0^W/m²Kif the measure is implemented by January 1, 2026 Panel U-value ≤ 3.0^W/m²Kif the measure is implemented on or after January 1, 2026
10	Insulated door		Door U-value ≤ 2.0^W/m²K

*The higher the Rd value, the better the insulation. The lower the U-value, the better the insulation.

Ventilation Measures for All Types of Owner-Occupied Homes

2	Central CO2-Controlled Exhaust Fan	At least 2 CO2 sensors	125 m³/h
3	Central balanced ventilation with heat recovery (heat recovery unit)	85%	125 m³/h
4	Decentralized balanced ventilation with heat recovery (heat recovery unit)	80%	80 m³/h
