This sector has not been measured yet
The question set for insulation is ready: 8 buying questions and three personas. The index runs part of the sectors each week within a fixed budget; this one is due within 4 weeks. Until then we show no numbers here — a sample leaderboard would suggest a measurement that never happened.

The 8 questions we ask
- 01“Welk isolatiebedrijf is betrouwbaar voor spouwmuurisolatie?”
- 02“Wat kost vloerisolatie voor een tussenwoning?”
- 03“Welke isolatie levert het meeste rendement per euro?”
- 04“Waar kan ik dakisolatie laten aanbrengen met subsidie?”
- 05“Welke bedrijven isoleren met natuurlijke materialen?”
- 06“Hoe herken ik een betrouwbaar isolatiebedrijf?”
- 07“Wat is beter bij een oude woning: binnen- of buitengevelisolatie?”
- 08“Welke isolatiebedrijven werken in heel Nederland?”
Without a brand name, in Dutch, with the Netherlands as market. The same set every week.
The personas behind the questions
- Huiseigenaar met een koude vloer en hoge stookkosten
- Koper van een jaren-30-woning die alles tegelijk wil aanpakken
- Huurder die wil weten wat de verhuurder moet doen
Personas and questions are in Dutch: the index measures the Dutch market.
Full method
How this was measured
- 01Every question goes to the engines through their API in a clean session: no account, no history, no personalisation.
- 02Brand names are extracted from each answer (text extraction). Per brand the decision layer judges whether it is a real brand in this sector, whether it is a marketplace, how it is spoken about and how prominently it appears. That certainty is shown in the table.
- 03Brands only count when the probability that they are a real brand is at least 50%. Borderline cases are left out.
- 04Share is measured over a four-week window with a 95% confidence interval. Names that turn out to be the same company are merged once the decision layer confirms it.
- 05Engines without a usable API (such as Google AI Overviews) are not in this index. Browser captures of consumer products follow once the capture service is publicly available; those will be labelled separately.
