Natural Wool Insulation
PURE WOOL INSULATION Benefits
Some of the Benefits of PURE WOOL LIFE INSULATION are:
Pure Wool Insulation: Improved Performance
Natural Wool Insulation by Wool.Life uses specially selected fleece wool from sheep raised on the lush green fields of rural New Zealand. Unique technology is used in our fiber processing to achieve the best thermal and acoustic values that will last a lifetime. Pure Wool Insulation will maintain its values for the life of a house.
Natural Wool Insulation by Wool.Life does not contain any harsh chemicals or odors and is the only 100% green insulation on the market. When crimped woolen fibers are carefully combed together, they form millions of tiny air pockets which capture air. These tiny pockets are what keep sheep warm in the winter and cool in the summer. This natural adaptation works in the same manner to insulate your home.
Because of wool’s resiliency, and the fact that wool absorbs harmful VOC’s (volatile organic compounds) found in many types of glue, paints, lacquers, and finishes, wool is the perfect insulation. Because natural wool is non-carcinogenic, fire resistant, hypoallergenic, and does not promote the growth of bacteria and dust mites, loose wool makes sense for anything that surrounds your family. PURE WOOL INSULATION by Wool.Life can be used as insulation for homes or even as a fiber filling on mattresses, comforters, pillows, and stuffed toys.
PURE WOOL INSULATION by Wool.Life is easily recognized as the cleanest wool insulation, as our product has been thoroughly scoured to remove dirt, oils, and debris.
Wool.Life loose wool insulation is a blend of sheep’s wool and lambswool from IWTO Certified Farms in New Zealand. Because of their youth, the core of the lamb’s wool fiber has yet to fill in. This hollow core creates more airspace, providing a higher resistance to heat flow and insulation value.
Our manufacturing process combs the wool into small knops (or balls), which gives the elasticity necessary for our insulation to resist compression and packing. These small knops capture pockets of air and provide an excellent insulation and acoustic value. Our loose fill wool insulation will retain its thermal value for 50 years
Pure Wool Insulation: Improved Insulation Value
Years of experience and research by our scientist Stephen Fookes gave the result of a unique natural wool product, our PURE WOOL INSULATION.
Natural Wool Insulation in batts and other similar wool insulation products were generating the same problem as regular insulation because it could shrink and compress over time. Some natural insulations were even treated with boric acid, a product that has been banned in some European countries due to its harmful effects on health.
PURE WOOL INSULATION by Wool.Life will not settle like many other forms of insulation, nor will it lose its Insulation Value with changes in temperature or humidity.
Our PURE WOOL INSULATION has an improved insulation value. We have selected a special blend of Sheep’s Wool and Lambswool and innovated a process to achieve the highest real world insulation value possible. This results in significant savings in your energy consumption (power bills, heating or cooling costs) and a more comfortable, regulated temperature in your house all year long. We can say we have developed a better solution with the same natural fiber.
Pure Wool Insulation: Improved Air Quality
PURE WOOL INSULATION by Wool.Life purifies the air. Its complex fiber structure absorbs and breaks down dangerous volatile organic compounds, such as Formaldehyde, in the atmosphere. PURE WOOL INSULATION helps maintain a constant indoor temperature and humidity which also contributes to maintaining cleaner air.
Wool absorbs VOCs within its core and rets them (breaks them down on the molecular level). Wool can purify indoor air for up to 30 years. Air pollution occurs when gases or particulate pollutants build up in indoor atmospheres without adequate air exchange. These Volatile Organic Compounds (VOCs) can build up in your home to harmful levels, thereby affecting your comfort and health.
There are three common gaseous indoor air pollutants with known adverse health effects. These are Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), and Formaldehyde (HCOH). Formaldehyde is found in fiberglass and has been classified as a known human carcinogen (cancer-causing substance) by the International Agency for Research on Cancer. These gases are often present as a result of building materials, interior furnishings and household chemicals, as well as heating systems, home appliances, and tobacco smoke.
The level of invisible contaminants directly impacts our and our family’s health and is frequently the culprit behind respiratory illness; eye, sinus, and throat irritation; headaches; dizziness; and fatigue (EPA 2008).
A true-life example of wool’s air-purifying ability occurred when pure wool insulation was installed into five buildings that had Formaldehyde concentrations that registered above 0.05ppm (The World Health Organization’s recommended level). Within 24hours of installation, German researchers recorded that the Formaldehyde concentrations had dropped below that level in all five buildings.
Wool also can help to relieve allergies, as its microscopic scales trap dust until cleaned or vacuumed, thus making the indoor air cleaner to breathe. The fibers of wool are too long and coarse to be inhaled, and so wool will not irritate the respiratory system or trigger an allergic response. This aspect especially sets Natural Wool Insulation apart from its competitors, as it can be installed without the use of respiratory equipment, protective clothing, or gloves. Additionally, our pure wool insulation can be blown into areas on top of existing insulation without disturbance.
Pure Wool Insulation: Safe in Fires
PURE WOOL INSULATION by Wool.Life will not maintain a flame at a temperature below 1,200°F. It requires more oxygen than is in the air to do so. It will only smolder and char if exposed to a continuous flame. Any fumes from burning wool are of very low toxicity, which lead to the claim from London’s Fire Chief “people are seven times less likely to die in a house fire where wool dominates compared to where synthetics dominate.”
Natural Wool Insulation is able to resist flame and does not easily ignite, due to its high nitrogen and moisture content. Because there is not enough oxygen to allow it to burn, wool will self-extinguish. Not only is wool a natural flame retardant but it also doesn’t emit noxious fumes, which can be toxic if inhaled. If burned, wool will not melt or drip like synthetic products, which quickly spread fire and fumes.
The safety of Natural Wool is the reason why wool is chosen by the preservation, hospitality, and contract sector to use in public buildings, as well as being endorsed by fire protection services around the world. For the same reason, wool carpet is the standard used in High-end Aircraft and boat carpets and upholstery.
When a home is insulated with natural wool, the occupants can rest assured that their families will not breathe in toxic fumes in the event of a fire.
Moisture and Mold Control
Excess Moisture and Mold are among the main causes of health problems and discomfort in the built environment. Buildings experience moisture buildup from human breath, perspiration, plants, cooking, and washing. This condensation accumulation promotes mold and mildew growth, which are detrimental to health. Additionally, excess humidity can promote dust mites. Wool has the natural ability to regulate the humidity of a room by absorbing moisture when the atmosphere is damp and releasing it when the atmosphere is dry. Wool can absorb nearly 40% of its own weight in water and still feel dry to the touch.
PURE WOOL INSULATION by Wool.Life manages humidity in the atmosphere like no other insulation fiber. At about 65% Relative Humidity (RH) Natural Wool Insulation will absorb moisture into it complex fiber structure. Once the RH drops below 65% it releases the moisture back into the atmosphere. This keeps a more constant humidity level in the room as well as helping to regulate the temperature. Managed moisture levels have a direct effect on the ability for mold to grow. Mold is a major contributor to allergies and bronchial problems.
Wool is an efficient moisture buffer in buildings, and because wool can “breathe,” it is ideal for clients in humid or damp climates. Because the insulating properties of wool are stable across a wide range of moisture levels, this provides more consistent performance in buildings.
Mold and Your Home
Mold spores are found both indoors and outdoors. Mold can enter your home through open doorways, windows, vents, and heating/air conditioning systems. Mold in the air outside can also attach itself to clothing, shoes, bags, or pets, and can and be carried indoors.
Mold will grow in places with a lot of moisture, such as around leaks in roofs, windows, or pipes, or where there has been flooding. Mold grows well on paper products, cardboard, ceiling tiles, drywall and wood products. Mold can also grow in dust, paints, wallpaper, conventional insulation, carpet, fabric, and upholstery.
In a word, wool helps to control mold Inside your home by controlling humidity levels and managing moisture.
Pure Wool Insulation: Bug Resistant
PURE WOOL INSULATION by Wool.Life does not harbor dust mite or other bugs. To eliminate the risk of moths and carpet beetles which would normally destroy wool, it is treated with a non-toxic bio-insect repellant.
All wool is treated with something to deter insects at the scouring stage, whether it is going to be a garment etc. Wool.Life has control of its entire processes, so our wool is washed with a small amount (0.25% by weight) of a non-ionic and non-toxic insect repellent called Eulan SPA which is based on the chrysanthemum plant. This is a liquid detergent added to the final scouring (cleaning) stage of the wool. It is absorbed into the inner core of the wool fiber, so it is not a topical deterrent or powder. This product is the industry standard for wool clothing etc.
Why to Avoid Boric Acid
We NEVER use Boric Acid because of the negative health effects associated with it. In December of 2010, the E.U. reclassified the ‘Borate’ group of chemicals that borax belongs to as a Substance Of Very High Concern (SVHC) due to its potential to be hazardous to reproductive health.
Borates have been classified as carcinogenic, mutagenic, or toxic for reproduction. Europe is usually several years ahead of America in regards to health (ie. GMOs are banned in Europe). Boric Acid has also been completely banned in Australia.
When Boric Acid is used in wool, it has to be applied at very high levels — 1% by volume, which is actually 8% by weight. This means that for every 100 pounds of “wool”, 8 pounds of it will be Boric Acid.
Pure Wool Insulation: 50 Year Warranty
PURE WOOL LIFE INSULATION will maintain its thermal and acoustic value for the life of the building.
PURE WOOL INSULATION by Wool.Life comes with a 50 Year Warranty. Because of its unique manufacturing technology, its thermal and acoustic properties never lessen. The use of wool as an insulator goes back thousands of years and is still significant in the health and wellness sector worldwide
Wool.Life Pure Wool Insulation maintains its resiliency due to its high bulk and elasticity. Resiliency is one of the main contributing factors to maintaining thermal efficiency over time. Because of the way that our knops (wool balls) are combed, our insulation does not compress or pack down like competing products, which experience R-value loss due to slumping. Our pure wool insulation is guaranteed to retain its thermal value for 50 years.
Wool.Life’s loose fill wool insulation is a blend of sheep’s wool and lambswool. Because of their youth, the core of the lamb’s wool fiber has yet to fill in. This hollow core creates more airspace, thereby providing a higher resistance to heat flow or insulation value.
Our manufacturing process carefully combs the wool into air capturing balls, which gives the elasticity necessary for our insulation to resist compression and packing. Contrary to other insulations which slump over time, Wool Life’s Natural Wool Insulation actually expands, guaranteeing that our loose fill wool insulation will retain or increase its thermal value as time goes on.
Committed to Animal Welfare
PURE WOOL INSULATION by Wool.Life is produced from healthy, pasture grazed sheep on the lush rolling hills of New Zealand. These sheep live comfortably in the clean and mild climate of New Zealand, being raised on responsible farms, and are sheared twice per year to maintain their comfort and wellbeing.
New Zealand maintains stringent Animal Welfare Regulations that are used by the International Wool Textile Organization. PURE WOOL INSULATION by Wool.Life is traceable through its direct supply from the farm to our manufacturing plant in the USA. 100% of our wool comes from IWTO Certified farms that we know and trust. Our wool truly is a Farm to Home high performance product.
Wool Life is committed to the highest standards of sheep welfare and well-being.
Animal welfare and caring for the environment are increasingly important to consumers, brands, and retailers. IWTO is committed to transparency in all stages of the wool pipeline, and animal welfare is very much a part of this commitment.
An animal is in a good state of welfare if it is healthy, comfortable, well nourished, safe, able to express innate behavior, and if it is not suffering from unpleasant states such as pain, fear, and distress” Good animal welfare requires disease prevention and appropriate veterinary treatment, shelter, management and nutrition, and humane handling.
Guidance provided by the internationally recognized 5 freedoms:
1. Freedom from hunger, thirst, and malnutrition – through ready access to fresh water and a diet sufficient to maintain full health and vigor;
2. Freedom from discomfort – through the provision of an appropriately sheltered and comfortable environment
3. Freedom from pain, injury, and disease – by prevention, or rapid diagnosis and treatment
4. Freedom to express normal patterns of behavior – through the provision of sufficient space, suitable facilities, and the company of the animal’s own kind
5. Freedom from fear and distress – ensuring conditions and treatments imposed avoid mental suffering.
Pure Wool Insulation: Easy To Install
Installing PURE WOOL INSULATION by Wool.Life is an easy and safe process whether you do it yourself or through a contractor. There is no risk involved in the installation of the product, no toxic off-gassing like spray foam, no boric acid like cellulose and other wool products, and no fiberglass particles suspended in the air.
PURE WOOL INSULATION is manufactured into air-capturing knops (small balls) to give it the elasticity that it needs to resist slumping. These small balls are designed to be blown into attics and walls, and because wool is a natural fiber, there is no need for any protective clothing, eye protection, or breathing apparatus during installation.
For the DIY it can be blown with a common garden vacuum/blower and 3″ hose. For higher productivity for professional installers, commercial industrial vacuum blowers are excellent for installation. We are happy to walk you through the installation process with helpful tips, links, and videos.
