Everything You Need To Know About Fireplace Insulation Material

In order to reduce waste and save as much money on your home’s energy system as you can, one of the best things you can do is to check your fireplace’s insulation system. Just by adding insulation to your fireplace, you will be able to drastically control the heat levels in your home.

Your goal with fireplace insulation materials is to adequately insulate your fireplace. This will make your fireplace more heat efficient. Start by sealing the gaps between your fireplace opening and the insert. By not doing so, you’re losing a lot of heat.

Closing the Gap

– Closing the gap in your fireplace dampers will be a two person job, so have a dependable coworker to help you. Begin by removing the cover plates, and then pulling the insert out far enough for enough space to stuff insulation into the gaps.

– Next, stuff fireproof insulation into the fireplace. The insulation should be fire resistant for up to two hundred and twelve degrees Fahrenheit, with a self-adhesive side of wrapped insulation.

– You can then slide the insert back into its former place, and reinstall the cover plates. If there is any loose insulation, it should be stuffed into any remaining gaps. If you need any additional help with this process, you can always seek the assistance of a chimney professional.


– Each type of insulation has its pros and cons. For example, loose fibers can easily be pressed with an adhesive to make them more beneficial. In contrast, fibers that are chopped can be easily placed into tight places. Foam insulations are most often used because they can also be applied as insulation for a number of outside surfaces. Without any further ado, here are some types of fireproof insulation materials:

– Fiberglass is melted glass that can be spun out into glass fibers. Fiberglass does not burn, however, it is often covered in paper or foil that will burn, so be careful about what you buy. Almost all fiberglass is officially rated as being fireproof, but as a general rule of thumb, they should not be used in temperatures in excess of twelve hundred and twenty degrees. This makes fiberglass a very versatile choice for many fireplaces commonly seen in homes today.

– Mineral wool is recycled from iron ore blast surface, but it can also be produced from natural rocks. Due to its very high melting temperature, mineral role is almost noncombustible. Being able to withstand more thermal applications, mineral wool is a very robust and durable type of fireproof insulation.

– Glass wool is produced from recycled glass. It traps air to practically block out the heat. Glass wool is very lightweight and also incredibly flexible, but the greatest benefit to it is the ease of installation.

– Fibrous mats are composed of many different kinds of minerals that when put together are called asbestos. Asbestos is well known for its strength and resistance to heat, but the most notable benefit of it is how it doesn’t conduct electricity. Asbestos is well used as insulation in many fireplaces today, and it’s also affordable in comparison to some of the other alternatives.
