Minimum requirement for roof insulation in rental residential buildings (Flanders)

A new standard introduced in Flanders, Belgium in January 2015 sets a minimum requirement for roof insulation in residential buildings, applied when the home is rented out. If a residential building does not meet the minimum requirements, it receives penalty points. From 2020 if a building or apartment receives more than 15 penalty points, the building will be ineligible for renting.
