Insulation is a mystery to most folks…










For those who are unfamiliar with insulation, making a healthy choice for this necessary feature in our lives can become confusing.


Fiberglass is probably the most familiar type of insulation when it comes to your home, available in both a batting and shredded/blown form. Fiberglass is essentially molten sand, spun like cotton candy. People like it because it’s easy to work with, is fire resistant, and makes a great insulation. One of the reasons we aren’t keen on recommending conventional fiberglass batt or spray insulation is due to it’s urea formaldehyde content, added as a binding agent. Urea formaldehyde is a known carcinogen, and contributes to poor indoor air quality as well as causes monumental issues for individuals with Multiple Chemical sensitivities. Formaldehyde exposure can trigger watery eyes, nose irritations, wheezing and coughing, fatigue, skin rash, severe allergic reactions, burning sensations in the eyes and throat, nausea, and difficulty in breathing in some humans. These effects can be compounded when your house breathes during typical temperature fluctuations. If possible, search your locp_Knauf_EcoBatt_Glasswool.jpgal area for formaldehyde-free fiberglass insulation, which can be found available in both batt and blown. We love working with Knauf EcoBatt insulation as a trusted, reputable source for toxin and formaldehyde-free fiberglass insulation. In lieu formaldehyde as it’s binder, Knauf EcoBatt insulation uses mineral oil and is safe for use by chemically sensitive individuals.



If formaldehyde-free versions are not available near you, choosing something traditional and sealing is your next best bet.  Use a garden sprayer and apply AFM Safecoat Safe Seal undiluted. Apply two light fog-like coats, with about 20-30 minutes between coats. Spray the exposed (inside) face before putting up drywall. Safe Seal can be used in a myriad of applications around the home, and is particularly useful with new construction conundrums like these.


Another commonly used insulation, spray foam, is at the bottom of our list as a healthy option. While it’s a great, effective product and can get deep within crevasses traditional insulation ccloseup-spray-foam-insulationannot, it is compromised of 100% synthetic chemicals, typically polyurethane. Spray foam is used quite often in new construction, in all areas of the house. If your new construction home is filled with the stuff, followed the aforementioned instructions on applying Safe Seal. This will prohibit the chemical hodgepodge from outgassing into your home.


Blown in cellulose has become clever option for recycle-minded. Made of shredded or modified paper, it seems like a great way to repurpose the material into something useful. We tend to caution our chemically sensitive customers away from using this as insulation material, as it it’s content is often chemically de-inked in addition to being treated with flame retardants. We do not currently have a solution to seal or treat cellulose in order to make it usable by those with MCS.


Cotton fabric that comes from pre-denimjeanconsumer denim jean scraps, can also be shredded and spun into a batt-like insulation, has peaked interest across the US.  Boric
acid is used to clean the fabric and provide flame resistance, but the use of dyes and subsequent de-inking chemicals makes this an expensive and somewhat suspicious product to recommend.


When considering insulation for your new or old home, our bottom line is to recommend a formaldehyde-free fiberglass. Breaking even for runner-up options include cellulose filling or Safe Seal-treated traditional fiberglass. Causing this tie- we’re not sure what might be contained in the treated-cellulose, but it’s also unlikely you’ll 100% seal all your home’s insulation with Safe Seal. It’s possible, however unlikely, to reach every cranny with a fog of this product. Remember, sealing is only as effective as it’s application, so make sure to be thorough, diligent and to manage those expectations. Regardless, Safe Seal can be incredibly effective in prohibiting the majority of in-house emissions from the insulation when applied properly.

Create a Natural, Healthy Bedroom

As an avid racquetball player, I’m often reminded that the best method for recovering from a twisted ankle is RICE: rest, ice, compression, elevation. It’s simple but highly effective. It gives the body the time and tools it needs to effectively heal itself. Rest at least six to eight hours a night. But how and where you rest might play a much bigger part in the healing process than you think. It’s even more important for common ailments like headaches, allergies and, counterintuitively, insomnia. One of the keys is to create a natural, healthy bedroom that promotes healing. Most people don’t realize that the average home contains 10,000 to 15,000 chemicals that are emitted from the building materials used during construction. While the number dwindles as the home ages, other chemicals are introduced in their place from clothing, cleaning materials, electronics, etc. Using flooring and wall finishes that are nontoxic and free of chemical outgassing will reduce the initial emissions by up to 75 percent. The use of a high-quality air purification system will ensure particulate capture, reducing allergens and that morning stuffy nose. The materials you surround yourself with during the night should be healthy and chemical free — most importantly, the mattress and bedding.


Flooring and finishes

While the feeling of something soft and cushy underfoot is nice in a bedroom, there really is no flooring material that is less healthy than carpet. Besides the chemicals that emit from carpet (for over 20 years!), carpet will trap allergens and pollutants that cannot be removed with vacuuming.  Hard surfaces, like wood, cork or, best yet, natural linoleum are recommended. These materials are far easier to maintain and keep clean. Natural linoleum is inherently anti-static and anti-bacterial, too. Anyone who really wants a soft surface to step on in the morning should consider a natural wool area rug. For wall surfaces, use nontoxic paint (not just zero VOC) or other natural finishes that do not outgas. Clay plaster, which is completely free of chemical outgassing and actually helps reduce chemical fumes in the rooms where it is applied, is a great option.

Mattresses and bedding

The average mattress contains chemical flame retardants, formaldehyde, heavy metals and various other VOCs. Look for a natural latex mattress encased in an organic cotton or wool cover. Not only is natural latex chemical-free, it is a responsive surface that provides pressure relief and appropriate support for your spine and specific shape. Unlike the synthetic “memory foam,” natural latex breathes, which discourages the buildup of moisture and heat in the mattress interior. No more musty smell! For sheets and blankets, look for natural and organic fibers that are GOTS certified. The Global Organic Textile Standard is the world’s toughest processing standard for organic fibers. Thus, consumers know that no pesticides or chemicals were used in the growing or manufacturing process.


Air purification

After everything else is done, the final bit of insurance is the implementation of a quality air purification device for the things you can’t really control. Dust, mold spores, pollen and outgassing from clothing and furniture can still build up in your bedroom. Portable purification units that use a four-stage filter containing medical-grade high efficiency particulate arrestance (HEPA) and activated carbon will address the most serious household airborne contaminants. There you have it. A quick and easy checklist for creating your healthy haven. You’re just a few steps away from a truly restful, healing night of sleep!

Do Green Schools Really Improve Student Performance?

Green Schools has been the hot topic in trade publications lately.  Do green schools really improve student performance? Touting natural daylighting, improved ventilation and a more "comfortable" approach to design, the green design and education communities want us to believe that these fresh ideas will somehow improve the 20 year slide in overall student academic performance.  I beg to differ.


I wrote an article about building healthy spaces about 10 years ago.  In that article, I refer to the trend towards connecting our indoor environment to the outdoors, with the use of natural daylighting and  materials that give the feeling of the outdoor environment, such as wood, cork, natural grasses, etc. Fortunately, the design industry listened to my recommendations.  However, also in that article was a long paragraph about the need to make sure that the materials in use are less toxic to the occupants.  A theme that seemed to get lost in the shuffle when these so-called "green" experts began to promote the idea of healthy schools.


The latest article on this topic points out that 71% of teachers and administrators in this one particular school said they saw a positive effect on student performance.  While this number seems fantastic, one needs to only dig a little deeper in the story to reveal that this number is based solely on perception, not any facts.  Stating "public school system privacy issues", they cannot actually give out performance numbers.  Nor can they tell us if student sick days have been reduced.  In essence, this public school cost 15% more to build, using tax payer funds, for the sheer argument of perception, not reality.


To create a truly healthy school, the materials used cannot just be considered green because they don't contribute to outdoor air pollution (VOC regulations).  You can't just focus on the energy saving HVAC designs either.  To really do this right, you MUST approach this project in a truly encompassing fashion.  Healthy materials, better design. Its a simple concept.
