Blown-in fiberglass insulation is a type of insulation material that is made up of tiny glass fibers. It is called blown-in insulation because it is installed by blowing the material into the spaces between walls, ceilings, and floors. This type of insulation is popular because it is affordable, easy to install, and has a high R-value, which measures the insulation’s ability to resist heat flow. Blown-in fiberglass insulation provides effective thermal insulation, which means it helps keep your home warm in winter and cool in summer.
However, whether blown-in fiberglass insulation is sufficient for your home’s efficiency depends on several factors. The first thing to consider is the climate in which you live. If you live in an area with extreme temperatures, such as very hot summers or very cold winters, you may need additional insulation to achieve optimal efficiency. The age and condition of your home’s existing insulation also play a role. If your current insulation is old, damaged, or insufficient, adding blown-in fiberglass insulation can significantly improve your home’s efficiency.
Another factor to consider is the size and layout of your home. Blown-in fiberglass insulation is effective at filling small spaces and gaps, but it may not be suitable for larger areas that require a more substantial barrier between the interior and exterior of your home. In these cases, you may need to consider other types of insulation, such as batt or spray foam insulation.
In summary, blown-in fiberglass insulation is an effective and affordable option for improving your home’s energy efficiency. However, its suitability depends on several factors, including climate, existing insulation, and the size and layout of your home. Consulting with a professional insulation contractor can help you determine the best insulation solution for your specific needs and budget.
