Biobased insulation in Gorinchem
Isoleerbewust insulates homes in Gorinchem 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 Gorinchem different
Climate, subsoil, build years and local schemes differ per place. These are the factors we take into account in Gorinchem.
Local point of attention in Gorinchem
Gorinchem's fortification is a protected townscape right on the Merwede. Inside the walls we insulate on the interior with a build-up that lets the thick exterior wall dry out after a wet spell.
Summer and winter temperature
Around Gorinchem the average daily maximum in July is roughly 23.0 °C and the average January temperature about 3.8 °C, with some 7 tropical days a year. Inland the extremes are wider: warmer summer days and colder clear winter nights. Degree days run higher than on the coast, so a thicker roof package pays back faster here.
Housing stock and build years
The stock in Gorinchem is dominated by vestingstad van voor 1900 plus jaren 70-90: vestingpanden en naoorlogse rijwoningen. We match the build-up to that, instead of applying a standard package.
Subsoil and moisture
Gorinchem largely sits on river clay in the river area. Groundwater rises noticeably during high river levels. We prefer floor insulation combined with a ground seal so evaporation from the crawl space does not reach the construction.
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.
