Fiberglass Insulation Alternatives

Insulation is one of the key ways to reduce the cost of heating and cooling in the long run. Therefore you need to make sure the right material is used when insulating your home. Although Fiberglass insulation is one of the most commonly used ones around, there are other materials available. So if you are shopping for insulation materials and don't want to settle for fiberglass, listed below are some alternatives you can consider.


Hemp insulation is another insulation alternative with immense advantages. Although largely unknown in the USA, hemp insulation has gained ground among those looking for eco-friendly insulation solutions. Hemp insulation offers many environmentally friendly and health safety features. Among its benefits is that it is Biodegradable and fully recyclable. Also, it contains no hazardous materials and does not attract insects or rodents. It can absorb moisture without losing its effectiveness.


Natural wool is another insulation material to consider. It can absorb a significant amount of moisture. It has no carcinogen; hence, you won’t feel any skin, eye, or respiratory irritation during the installation process. Wool insulation can also help to improve indoor air quality. This is because wool absorbs indoor air pollutants. Wool is also effective in blocking sound.

Aerogel Insulation

Although aerogel is a synthetic insulating material, its components are 90 percent air. As a result of this, it is difficult for heat to pass through the material. This material was invented in 1931 by Samuel Stephens Kistler. Aerogel is made by removing the liquid from silica using high temperature and pressure.

Polystyrene Insulation

This insulation material comes in two forms; rigid foam boards and spray foam. This material is a plastic that is also considered an eco-friendly insulator because it tends to save a considerable amount of energy when in use. The rigid foam board is installed in the walls not only to insulate the home but also to give a better structure.

Thermacork Insulation

This is a natural, renewable, and eco-friendly insulating material. It is known for its ability to cancel noise and provide an adequate amount of heat depending on the season. Although this material has a negative carbon footprint due to the source of its finishing, it is free of toxin and, therefore, suitable for humans and the environment.

Sheep's Wool Insulation

This is an eco-friendly insulating material. It is one of the best options for extremely cold weather. Since the inner layer of the wool fiber is able to resist water, it is thereby able to prevent condensation. These are some of the fiberglass Insulation alternatives in the market right now.
