Growing up, one of my favorite gifts for college was clothing. Budgets back then were tight, so any contribution to the clothing fund was always appreciated. In particular, I looked forward to getting the wool sweater that my aunt and uncle would bring me every year when they returned from their annual trip to Ireland. These sweaters were always one of my favorite pieces of clothing. Why? Because they could be counted on to keep me warm in the cold winters in Albany, NY.

For thousands of years, sheep have been able to survive harsh summers and winters. Due to their crimped nature, wool fibers form millions of tiny air pockets that trap air, helping to give a breathable thermal barrier β and thus keeping the sheep warm during winter and cool in the summer months. If nature so effectively uses βwool coatsβ to protect sheep from extreme cold and heat, why not do the same in our homes?!
To be clear, insulation is extremely important to energy efficiency in our homes. It provides an easy way to cut greenhouse gas emissions. All while saving on utility bills. According to a study by the Boston University School of Public Health, increasing insulation levels in existing U.S. single-family homes to the 2012 International Energy Conservation Code (IECC) level would reduce electricity consumption across the United States by 37 billion kilowatt-hours. Thatβs equivalent to the annual electricity usage of 3.4 million U.S. homes.

As Iβve written: βWhile keeping your place cold can be a serious energy drain, keeping it warm can also be a heavy load. The furnaces and heaters you use to keep comfortable on cold days can use a lot of electricity, especially if your home isnβt insulated well. Many homeowners looking to winter-proof their home are now choosing earth-friendly materials such as hemp, cotton, and sheepβs wool. Using those sustainable materials can help you stay toasty warm while keeping your carbon footprint at a minimum.β
While other types of insulation such as, glass, mineral wool, cotton and foam are commonly used in homes, wool insulation, in my opinion, is the best option. Makes me think of that song, βNothing Compares 2Uβ by Sinead OβConnor! All the other forms of insulation just canβt come close to the capabilities of wool. Thatβs why, when a company like Havelock Wool makes sheep wool insulation, I listen and do the research.
Again, wool has certain characteristics that make it able to breathe. Moisture can be absorbed and desorbed against up to 65% relative humidity. Thereby keeping a home dry and comfortable while helping to prevent rot and mold. All which can lead to expensive repairs and health concerns. Unlike many types of manufactured insulation, wool insulation doesnβt settle and can keep up its R-value for 50 years. Itβs also fire-resistant and is an excellent acoustic insulator. Plus, natural wool is 100% compostable.

My friends at Havelock sent me a bat of insulation. I left it in my living room for three weeks. No breathing problems! So hereβs my video on installing it and how easy it is on your health!!
Now, we know that synthetics contain harmful chemicals. Yes. Even glass batt insulation. In the case of wool insulation, harmful chemicals such as formaldehyde, nitrogen oxide and sulphur dioxide are actually trapped by the wool and removed from the air. No other type of insulation offers this unique ability. In fact, most other types of insulation are emitting harmful chemicals and/or adversely affecting indoor air quality. I totally do not like going into my attic because the old glass batt insulation up there creates almost βfilmyβ air. For that reason, I never visit my attic without a mask. If my entire attic had wool insulation, I wouldnβt have that issue at all.
So, why Havelock Wool? For starters, they offer a choice of batt insulation, or loose fill if thatβs your choice. The insulation is 100% wool with no synthetic mix. Itβs also compostable following an extended useful life. Add in flame resistance, and great thermal regulation and acoustic insulation properties. Therefore itβs hard to beat. Oh, and no protective clothing or added safety measures required while installing it. That says a lot.
Frankly, as I transition from my old insulation, Iβll be using greener alternatives like Havelock. Iβm tired of worrying about going into an attic that feels unsafe to be in.
Thanks to the sponsors Havelock.
