Also, with no heat coming in through the ceiling, it will stay cool inside for much longer periods of time. Take a look at some of the advantages of aerolite.
Ceiling Insulation Materials In Winter
In the wintertime, roof insulation products work the opposite way. Hot air rises, so all the warm air you generate inside your home escapes through the ceiling. Once you have a well-insulated ceiling, the warm air generated will stop leaking out and stay in the areas that give you a comfortable living environment. You also won’t need to run the heating systems all night. Insulating materials retain the heat inside your home for much longer periods of time. This, in turn, reduces your power consumption and saves you money in the long run. Some of the advantages of isotherm.
