Methodology

How this guide
is written.

Every page on this site follows the same approach: start from public sources, cross-check with experienced installers, and rewrite in plain language. No supplier supplies the copy, and no supplier reviews it before publication.

In het kort

Vier vuistregels

  • Vergelijk minimaal drie bedrijven op meer dan alleen prijs.
  • Beoordeel materiaal, isolatie, montage en garantie afzonderlijk.
  • Controleer altijd vergunningseisen bij uw eigen gemeente.
  • Een lage prijs zonder specificatie is een waarschuwingssignaal.

Checklist

Step by step

  1. 01Outline the question a reader actually has, in their own words.
  2. 02Gather public sources, manufacturer data and installer experience on that question.
  3. 03Draft in plain language — short sentences, no jargon without a definition.
  4. 04Cross-check against the Dutch building code and council rules where relevant.
  5. 05Read it back as if you were the homeowner: is the answer clear, is the trade-off honest?
  6. 06Publish, then revisit when rules, prices or product ranges change.

Conclusie
The point of the method is simple: give readers the same information a careful, experienced friend in the trade would give them — without trying to sell them anything.
