FAQs

What is Rock Wool?

Rock wool, also known as stone wool or mineral wool, is an eco-friendly insulation material that gets created when molten rock and limestone are spun into fibers. The final product can be used for home heating systems, commercial building projects, industrial furnaces, and more. A high density of flame retardant chemicals are added to the rock wool before it is spun, making this type of insulation safe for use in residential and commercial buildings.

How does Rock Wool work?

Rock wool works by trapping pockets of air within its fibers which act as an insulator for your home. Because of its high density, rock wool can trap heat produced by your furnace, keeping it where it belongs – inside of your home. Rock wool is also able to trap humidity which further helps keep the air in your home warm and dry during cold winter months where you are forced to turn up the heat.

Before installing rock wool insulation, it is important to make sure you have the right tools for the job. A staple gun with heavy duty staples up to 1/2 an inch long will be needed as well as a framing hammer and circular saw. The first step in installation is clearing out all of your old insulation materials followed by adding building insulation.

Conclusion

While natural fireplace rock wool insulation has many benefits, there are a few setbacks you should be aware of before purchasing it. For example, if your home contains an old chimney made from brick or stone and not metal, this type of material may flake off into your house because it can be fragile. The same thing can happen if you do not install it properly or if some of your bricks are damaged in the process, which may lead to dangerous living conditions.
