Which Dutch subsidies apply to home insulation?

Homeowners in the Netherlands can access the national ISDE subsidy through RVO. Combining two or more measures allows claiming back up to approximately 30% of costs.

What energy savings can I expect from roof insulation?

Up to 30% of domestic heat escapes through an uninsulated roof. Insulating the roof delivers immediate thermal improvement and noticeable reductions in gas consumption.

Can underfloor heating be poured directly over foam concrete?

Yes. Foam concrete provides a lightweight, moisture-resistant subbase. Underfloor heating pipes are laid on fixing tracks, followed by a level screed floor.

How quickly can an insulation project start?

Following an on-site survey and quotation sign-off, we schedule the works. Specific insulation tasks take several days, while complete floor replacements take roughly 2 to 3 weeks.

From Thermal Insulation to Balanced Indoor Comfort

A comfortable, sustainable home begins with the building envelope. Without proper thermal insulation, substantial heating energy escapes through the roof, external walls, and suspended ground floors. Heidstra Bouw upgrades your home's thermal shell systematically.

We evaluate the complete building envelope: insulation values, airtight sealing, vapor control, and adequate ventilation. Aligning these elements ensures high long-term efficiency and prevents interstitial moisture issues.
