Insulation helps to keep your house warm by slowing down the transfer of heat from inside your home to the outside. Heat naturally flows from warmer to cooler areas, and insulation provides a barrier to this flow by trapping pockets of air within its material. This trapped air acts as a cushion, reducing the amount of heat that can escape through the walls, roof, and floor of your home. The more insulation you have, the better it will be at keeping your home warm, since it will provide a thicker barrier to heat transfer.
There are several different types of insulation materials, including fiberglass, cellulose, spray foam, and rigid foam board. Each has its own unique properties and can be more or less effective at insulating your home, depending on the climate, your home’s construction, and other factors. To determine the best type of insulation for your home, it is recommended to consult with a professional who can assess your specific needs and make recommendations based on your specific circumstances.
