You've got a hole in your attic, and you're not sure which type of insulation will do the best job of sealing it. That's okay! Attic Chief experts are there to help you. If you're looking for ways to increase the energy efficiency of your home, then there are plenty of options out there.

But some types are better than othersand that goes for attic insulation as well as other kinds of insulation. In this article, we'll break down some common types of insulation and explain their pros and cons.

Cellulose insulation : Pros and cons


Cellulose insulation is made from recycled newspaper, and it's a great option for anyone who wants an affordable and easy way to insulate their attic. Because cellulose is made from recycled paper, you won't find any off-gassing or fumes that come with using another type of insulation such as fiberglass. Another benefit to using this type of insulation is that it's fire resistant and mold resistant.


One downside to using cellulose is that it doesn't provide much protection against moisture buildup in your attic space or against rodents like mice or squirrels because there are no fibers holding the material together like other types of insulation do.

Fiberglass insulation : Pros and cons


Fiberglass insulation is ideal for cold climates because it's designed to trap heat. It's also a good option if your home requires fire codes.


This type of insulation is more expensive than other options, so it may not be the best option if you're looking to save money on energy bills. If you live in a hot climate, fiberglass may not be effective at keeping your space warm because it doesn't insulate as well when temperatures rise above 70°F (21°C).

Rock wool insulation


Rock wool provides excellent insulation for high-humidity areas and is also fireproof. Because of its natural resistance to heat and water damage, it’s a great choice if you live in an area with high humidity or frequent flooding.


It’s important to take extra care when installing this type of insulation. Also keep in mind that rock wool tends to be more expensive than other types of attic insulation.

Mineral wool insulation


Mineral wool insulation is fire resistant. It won’t catch on fire, even if exposed to high heat or flames. In fact, it can be used under roofs as part of a fire-retardant roofing system. Mineral wool insulation is durable and non-toxic.


Mineral wool isn't as efficient as fiberglass insulation.

Reflective insulation


If you want to reduce your energy bills and your carbon footprint, reflective insulation is a good choice. The reflective material reflects heat back into your home during the cold months, which means that the air in your home won’t get too hot or too cold. This will allow you to use less energy when heating or cooling your house.


It can be difficult to install because it requires some advanced DIY skills and tools. It can also be expensive.


If you’re in the market for attic insulation, you might be confused about which type is best for your home. There are a lot of options to choose from, but we hope this article has helped clear things up and lead you down the right path.
