If you are looking to insulate your new home, or re-insulate your current home, you’ve come to the right place. Here, we will answer the questions “What is insulation?” and “How does insulation work?” We’ll discuss in detail exactly what insulation is and how it works to protect your home and keep you comfortable all year round.
So, what exactly is insulation, you may ask?
What is Insulation?
Essentially, insulation is any material used to fill the spaces (including little gaps, crevices and hard-to-reach places behind walls, above ceilings, etc.) of your home to reduce heat flow by reflection and/or absorption.
There are several different types of insulation, including soundproofing insulation, electrical insulation and thermal insulation. When discussing insulation in relation to your home, it is thermal insulation that increases energy efficiency and comfort levels. Thermal insulation is defined as products that reduce and slow heat loss or gain by providing a barrier between areas that are significantly different in temperature. Many forms of thermal insulation, such as cellulose and fiberglass, also provide soundproofing to some extent.
How Does Insulation Work?
Heat flows naturally from warmer areas to cooler ones. During the winter, heat moves directly from warm spaces (such as your home!) to outdoors and unheated spaces. During the summer months, heat moves from the warm outdoors to the cooler interior of your home.
Insulation works by slowing the movement of heat from a hot space to a cooler space. Insulation helps increase the energy efficiency of your home by reducing the amount of heat that escapes from it in the winter (containing the heat and keeping the house warm) and keeping it from getting too warm in the summer months (retaining the cold air and keeping the interior comfortable).
When installed properly, insulation can increase the comfort levels of your home by maintaining a consistent, uniform temperature from room to room. Insulation will also increase your home’s energy efficiency, significantly lowering heating and cooling bills.
There are several types of thermal insulation to choose from, including:
Many types of insulation – fiberglass, cellulose and foam board – absorb heat. They stop heat flow known as conduction. Radiant barrier, on the other hand, reflects heat from the sun and is installed in attics to keep homes cool and comfortable (and much more energy-efficient). As its name suggests, radiant barrier insulation stops radiant heat transfer.
