Comparing Fiberglass And Rock Wool Plumbing Insulation


Plumbing insulation is designed to keep your pipes sufficiently heated during the winter months, reducing the risk of the water within them freezing and causing the pipes to burst. Burst pipes can result in a great deal of water damage to your home, an expensive plumbing repair bill, and the possibility of mold and mildew growth, a major health concern. There are two main types of plumbing insulation available on the market, both of which perform the same function but offer a distinct set of advantages. Understanding what each type of plumbing insulation has to offer can help you choose the one that best fits your home's plumbing needs.


Fiberglass insulation is made out of recycled glass fibers and is the more affordable option for plumbing insulation. This option is ideal for homeowners operating under a tight budget. It comes in either pre-molded forms that fit around standard pipe diameters or in blankets which can be draped and taped to pipes of larger sizes. There is a wide range of different thicknesses available, offering greater insulation at a greater price point.

However, when compared to rock wool, fiberglass is not as effective at insulating pipes. Fiberglass is also susceptible to fire damage, as it burns at a lower temperature when compared to rock wool insulation. This makes fiberglass insulation the lesser choice in extremely cold climates or in areas where the risk of fire is a possibility (dry areas prone to wildfires, for example).

Rock Wool

Rock wool insulation is the premium type of plumbing insulation, offering better performance in below-freezing temperature for your pipes. This option is ideal for homes located in extremely cold climates. Rock wool is also much denser than fiberglass, which makes it better at insulating noise from your pipes, a major benefit if your home's plumbing clangs when water moves through it. Additionally, rock wool insulation has greater fire resistance when compared to fiberglass, which makes it a better choice in areas where fires are a real risk.

However, rock wool is available at a higher price point when compared to fiberglass and does not come in as wide a range of thicknesses as fiberglass does. It also does not come in blanket form. This is not ideal for homeowners who have to stay within a budget, and it also makes it harder to insulate pipes that are a nonstandard size.

plumbing mistakes - when to call in the pros

Do you know when to call a plumber? I had it in my head that plumbing was a simple system in my home that I could manage myself, but quickly learned otherwise. After completing a bathroom renovation myself and having a few of the water and drain pipe connections fail, I quickly learned that it was one job that I should have left to a professional. My website offers you simple solutions to small plumbing issues and a short guide to help you determine if your best option is to call in the professional plumbers. Hopefully, my mistakes will help you learn what not to do in your home.
