Old house is cold house
One reason to produce this 35-minute film about insulation construction (in six steps) was the harsh criticism that thermal insulation, especially wall insulation with polystyrene, has recently been exposed to: insulation does not bring anything, it does not pay off, it causes Mold and is even considered a fire accelerator! The film investigates these arguments with an open mind and wants to get to the bottom of the question: is this criticism of insulation for energy saving justified or not.
