We're all looking for ways to improve energy efficiency, save some money, save the planet—all those good things. But it can sometimes be a challenge to figure out what exactly is going to make a difference in how our heating and cooling systems operate. One thing that can have a tremendous impact is insulation.
How Heat Moves
Heat moves in three ways: conduction, convection, and radiation. Conduction is when heat moves through solid materials such as uninsulated walls and windows. Convection is when heat moves through liquid and gasses, like when cold air comes through an open window and mixes with the warm air lowering the overall temperature. Radiation is when heat transfers through space, like when sunlight enters a room and warms it up.
How Insulation Works
There are different types of insulation. Bulk insulation helps prevent heat loss by allowing for pockets of air within the insulation that prevent heat conduction from the inside of the house to the outside of the house. It keeps the heat from moving out through the walls of your house.
Reflective insulation works by reflecting radiant heat back into the home so it can’t radiate out through the walls. This insulation combined with bulk insulation provides pretty comprehensive prevention of heat loss.
How Does This Affect My HVAC System?
The more heat that’s lost through the walls of your home, the harder your heating system has to work to keep up with the temperature demands set by your thermostat. The harder your heating system has to work, the more energy it uses. The more energy your HVAC uses, the higher your utility bills each month.
Proper insulation in your home not only helps keep your home more consistently comfortable throughout the year, but it also helps lower your utility bills by allowing your heating system to work less.
