Discover Insulation Solutions that Are Not Fiberglass to Keep Your Home Comfortable

When it comes to duct insulation, many homeowners are now steering away from traditional fiberglass material due to its potential health risks. If you’re looking for alternatives to fiberglass duct insulation, there are several to choose from.

For modern alternatives, Urethane is one of the best options. Poured into place as a foam from a can, it hardens and provides secure insulation around ducts. It can be a bit more expensive than other materials, but it’s also the most effective and widely used.

Vinyl insulation is the most commonly used alternative to fiberglass and can easily be wrapped around the duct. It’s relatively cheap and can be a suitable option, although folds or spaces between layers can minimize its effectiveness.

Wood insulation is a great green alternative. With wood, such as bark, wrapped tightly around your ducts and held down with tape or caulking, it’s a cost-effective and eco-friendly choice. Its effectiveness may not be on par with the remaining options, however.

Cellulose insulation is another green alternative. This foam-based material is made from recyclable materials, so it’s a great choice for those looking to help the environment. Additionally, you could use straw or old newspapers around the duct, sealed securely with caulking.

Ultimately, the choice of insulation all comes down to preference, health risks associated with fiberglass, and cost. Urethane offers the best overall protection, but for a cheaper, greener option, cellulose foam, straw, and newspapers could all provide adequate insulation.
