How to insulate the ceiling with foam

The most popular materials for insulating ceilings are polystyrene and mineral wool. Let’s compare them.

So, mineral wool is an inorganic fiber that does not emit any harmful elements, is not toxic and is relatively cheap. The advantages are undoubtedly very important, but there is one significant drawback – poor hygroscopicity. With high humidity, mineral wool significantly loses its thermal insulation properties, and this already affects the temperature in the house.

Unlike mineral wool, foam as a finish shows a more complete set of positive qualities. It does not need thorough vapor and waterproofing. But here, too, one cannot do without cons – this material is very flammable and costs more than mineral wool. Also, some experts claim that the foam emits harmful substances into the atmosphere. This statement is rather controversial and unproven, so you shouldn’t dwell on it.
