"Attic insulation is an important phenomenon that should be adopted by every home having a heating or a cooling appliance. In fact, those without an HVAC unit must also think carefully about attic insulation. Attic insulation is a way of preventing heat flow to and from the house and there are several benefits associated with attic insulation. They are the following:Attic insulation increases the comfort levels within the house. This is because there is no heat loss from inside the house during the winter months and at the same time there is no heat gain from outside during the summer months.Attic insulation ensures cost savings because the HVAC units need not work extra hard to produce the desired level of cooling or heating as there is neither heat gain or heat loss. Moreover, when there is no extra stress on the HVAC units they last longer.Protecting homes against moisture damage is another advantage of attic insulation as rain or snow cannot get inside the homes through the roofs of the attic. In case rain or snow gets inside a house it will cause moisture damage which in turn will create overall structural damage to homes.Lastly, attic insulation has a positive impact on the environment as the emission of harmful byproducts from heating and cooling units are less as these units need not work as much as they would have to work when an attic is not insulated."
