Biobased insulation in Montfoort
Isoleerbewust insulates homes in Montfoort 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.
What makes insulating in Montfoort different
Climate, subsoil, build years and local schemes differ per place. These are the factors we take into account in Montfoort.
Local point of attention in Montfoort
Around Montfoort the groundwater is high in the peat meadow area and crawl spaces are often too low to work in. Insulating from the top of the floor, or blowing material into the crawl space, is usually the only workable route.
Summer and winter temperature
Around Montfoort 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 Montfoort is dominated by kern van voor 1900 en jaren 70-90 uitbreiding: dorpse rijwoningen en twee-onder-een-kap. We match the build-up to that, instead of applying a standard package.
Subsoil and moisture
Montfoort 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.
