As the weather starts to get cooler once more, you may be wondering how you can keep your house warm and energy bills low this coming winter. The answer? Insulation. Insulation is a material that acts as a barrier to both heat loss and heat gain. In residential homes, insulation is most commonly installed in roofs, ceilings, walls and floors. Insulation is one of the most cost-effective and practical ways to ensure your home is cooler in the summer, warmer in the winter, and much more energy efficient year-round. Not only that, but insulation also works to reduce the amount of condensation in your home, which in turn reduces mold, dampness and other unwanted air pollutants from infiltrating your home.
How Does Insulation Work?
In basic terms, insulation works by stopping the transfer of heat. In winter, this means preventing the cold air from outside infiltrating inside, which keeps the home warm. In summer, insulation works by trapping the cool air inside, while at the same time stopping the heat from outside coming inside. Insulation not only ensures your home is comfortable by keeping a consistent indoor temperature, but it also reduces how often you need to use your home’s air conditioning system. This is what makes insulation an important feature of any energy-efficient home.
The Different Types of Insulation
There are a few different types of insulation, each type is used in different areas of the home for varying insulating needs. Here are the four common types of insulation used in residential homes:
- Blanket insulation. Blanket insulation is filled with mineral fibers, including rockwool and fiberglass and comes in a rolled-up form.
- Polyurethane and polyisocyanurate foam insulation. This type of insulation is sprayed into the crevices and cracks of a home to prevent air leakage.
- Loose fill insulation. Loose fill insulation is made of cellulose, rockwool and/or fiberglass and comes in pellets or fibers.
- Rigid insulation. Rigid insulation is generally installed in boards or pipe fittings and is used to insulate wall sheaths and foundations.
