Biobased insulation in Krimpenerwaard
Isoleerbewust insulates homes in Krimpenerwaard with natural, vapour-open materials: hempfibre, cellulose, woodfibre and strawboard. We tailor the construction to the age and detailing of your home, instead of forcing a standard package onto it.
Also active in: Schoonhoven, Haastrecht, Bergambacht, Lekkerkerk, Stolwijk, Vlist, Ouderkerk aan den IJssel.
What makes insulating in Krimpenerwaard different
Climate, subsoil, build years and local schemes differ per place. These are the factors we take into account in Krimpenerwaard.
Local point of attention in Krimpenerwaard
In the Krimpenerwaard many homes sit on or against a dike, with half cellars and crawl spaces that follow the polder water level. In dike houses the biggest heat loss is usually the thatched or tiled roof and the floor-to-facade joint, not the wall itself.
Summer and winter temperature
Around Krimpenerwaard the average daily maximum in July is roughly 22.4 °C and the average January temperature about 4.1 °C, with some 5 tropical days a year. An average Dutch climate with a clear urban heat effect: in dense districts summer night temperatures run several degrees above the countryside. Roof insulation with high heat capacity therefore matters as much in summer as in winter.
Housing stock and build years
The stock in Krimpenerwaard is dominated by boerderijen en lintbebouwing van voor 1940, plus jaren 60-80 dorpsuitbreiding: vrijstaande boerderijen, dijkwoningen en dorpse rijwoningen. We match the build-up to that, instead of applying a standard package.
Subsoil and moisture
Krimpenerwaard largely sits on peat with a high groundwater table. Crawl spaces here are often wet; relative humidity under the floor reaches 85-95% in summer. Vapour-open insulation and a well-ventilated, sealed crawl space matter more than a high Rd value alone.
Grants and financing here
Nationally the ISDE insulation grant applies: the amount per m² doubles when you carry out two or more measures at once. On top of that almost every municipality has a sustainability loan, and the National Heat Fund provides financing, at 0% interest for lower incomes.

Why Isoleerbewust in Krimpenerwaard
- Knowledge of Dutch housing stock. We adapt the build-up to brick cavity walls, wooden floors and tiled roofs typical for the region.
- Vapour-open by default. Our standard details let walls and roofs dry out, instead of trapping moisture.
- Own crew, no chain of subcontractors. Same people from quote to delivery. One point of contact.
- Transparent pricing. Concrete price per m², no vague 'from' prices. The price indicator gives a serious range.
