Efficient Insulation Options For Older Homes

If you own an older home, you may be familiar with the challenges of keeping your home warm in the winter and cool in the summer. One of the most important steps in improving the energy efficiency of your older home is to ensure that it is properly insulated. In this article, we will explore some of the best insulation options for older homes.

Blown-in Insulation

Blown-in insulation is a great option for older homes that have open spaces that are difficult to access. This type of insulation is made up of small particles of material such as fiberglass or cellulose, which are blown into the space using a specialized machine. Blown-in insulation can fill in gaps and holes without the need to tear down walls or remove any existing insulation. This makes it an ideal solution for older homes that may have drywall or plaster walls that cannot be removed.

Spray Foam Insulation

Spray foam insulation is another popular option for older homes. This type of insulation is made up of a mixture of two chemicals that combine to form foam. The foam expands to fill the area where it is applied and creates an airtight seal. Spray foam insulation is more expensive than other insulation options, but it provides superior coverage and is very effective at reducing air leakage.

Batt Insulation

Batt insulation is a traditional type of insulation that comes in long rolls or sheets. This insulation is made up of fiberglass or rock wool and is often used to insulate walls, ceilings, and floors. Batt insulation is easy to install and can be cut to fit into any space. It is also relatively inexpensive compared to other types of insulation. However, it can be less effective if not installed properly, and can leave gaps and spaces for air to pass through.

Reflective Insulation

Reflective insulation is a type of insulation that is made up of multiple layers of reflective material, such as aluminum foil. This insulation is installed in attics, walls, and floors and works by reflecting heat away from the home. Reflective insulation is ideal for older homes that receive a lot of sunlight and heat, as it can help to reduce the amount of heat that enters the home. However, it is less effective in colder climates and does not work well in areas with high humidity.

Window Insulation

Another area that homeowners can consider to improve the insulation of their older homes is windows. If you have older, single-pane windows, it may be worth considering upgrading to double-pane windows with low-E coatings. These coatings can help to improve the insulation of your windows and reduce heat loss during the winter months.


Proper insulation is a crucial factor in keeping older homes comfortable and energy-efficient. With the options available, homeowners can choose an insulation type that fits their needs and budget. Blown-in insulation, spray foam insulation, batt insulation, reflective insulation, and window insulation are all effective ways to improve the energy efficiency of your older home. When installed properly, these methods can help to save money on energy bills and reduce the environmental impact of older homes.
