Complaints about carpet pad odors show that researching the underlayment is just as important as the carpet that goes over it green-labelThe homeowner was almost distraught. She had just invested in a high-quality nylon carpet, only to deal with chemical fumes throughout her home as soon as the installation was complete. Now, she was spending hours doing research on the Internet, and she called Natural Interiors® for help. She had a remnant of the carpet and had isolated it long enough to know that it was not the problem. The odors, she had determined, must be coming from the carpet pad. “Can you tell me about chemical-free wool carpet and pad that you carry?,” she asked. “I am thinking that I may need to redo this whole project.” I replied: “Is the company that sold you the carpet and pad going to give you your money back? It would be a real shame for you to have to pay twice for the same job.”

U.S. vinyl flooring manufacturers are aware of the dangers and have taken steps to eliminate phthalates from their vinyl products. To be sure, there are questions you should ask. DSC_0325Q: I have put my plans to put vinyl flooring in my kitchen and family room on hold because of news reports about phthalates in vinyl flooring. Why is this information just coming out now, and can you recommend an LVT (Luxury Vinyl Tile) that does not contain these chemicals? A: This is not new news. The Consumer Product Safety Commission and the U.S. EPA have been looking at potential health concerns with phthalates for more than a decade. It began in the 1990s, with studies, and then rules restricting phthalate use in children’s items, like rattles and teethers  -- things that they would routinely put in their mouths.  Flooring was not on the list. More recently, the U.S. EPA has issued an action plan for several phthalates, some of which have been used in vinyl flooring.

Low- and zero-VOC hardwood finishing program expands with architect’s vision OLYMPUS DIGITAL CAMERACincinnati Architect Adam Fosnaugh was in awe of a wood floor made in Denmark. It was the look he wanted for the first floor of the Clifton home he and his wife are remodeling. Could we recreate this aesthetic?, he asked. It was White Oak plank, bleached in color, not too white, but no yellow tones that are typical with traditional hardwood finishes. Oh and yes, it had to be low- or zero-VOC. Adam is a LEED AP at MSA Architects. His wife, Margot, is a chemical engineer and air quality consultant, and they have a 1-1/2-year-old daughter. Indoor-air quality, in addition to the perfect color, also would be important for the cork flooring they would select for the second floor.

Indo Teak flooring is durable and planet-friendly, but also serves as a tribute to the travels of St. Xavier DSC_0297Don’t be misled by the Forest Stewardship Council (FSC) Certification that comes with this Teak flooring. It does not mean the wood came from a sustainably managed forest. Instead, it comes from deconstructed structures in Indonesia – some up to 300 years old. And it has proven  to  be the perfect look for the northern foyer at St. Xavier Church in downtown Cincinnati.  Church administrators' desire for sustainable products and durability was a key reason Architects Paul Duffy and Adam Luginbill  at glaserworks selected it.

Questions about chemicals in flooring are now common for the mainstream flooring shopper FloorScore LogoSomething is changing in the flooring industry. Customers are asking more frequently about what chemicals the products contain. Though there is no national statistic on what percent of the population has concerns, it is safe to say that 2015 should go down in history as the year mainstream consumers gained noticeable awareness of how flooring can impact indoor-air quality and human health. It started in March, with the 60 Minutes report that alleged excessive formaldehyde was being emitted from cheap glue used to make some of Lumber Liquidator’s laminate flooring in China. A second wave of concern erupted weeks later when it was announced that The Home Depot would phase-out sales of vinyl flooring that contained ortho-phthalates.

Confusion and half-truths follow report of excessive formaldehyde in some Lumber Liquidators’ laminate floors Carb II CompliantA customer who has seen the 60 Minutes report about unhealthful levels of formaldehyde in certain laminate floors from Lumber Liquidators now is questioning a flooring purchase she was about to make. “No worries,” her salesman says. “All of our flooring meets California Air Resources Board (CARB) standards for formaldehyde.”  He is misleading, but not intentionally. To assist its salespeople, a national retail group issues an alert to its members that reads: “All of our laminate flooring meets CARB 2 standards.”  Another over-simplification. Most flooring retailers – including those touting “natural” products – have limited understanding of how to gauge a floor’s impact on indoor-air quality. Understanding the evolution of people-friendly products, and keeping up with the ever-changing status of which manufacturer has added a certification and what the certification means, is a specialized field of its own. Compounding the confusion, certifications expire annually.

Onsite, UV-cured hardwood floor finishes are starting to beam BulldogWe talk a lot about low-VOC (Volatile Organic Compound) floor finishes, and the scientific advancements that have produced less-toxic polyurethanes and natural oil floor coatings.  But the truth is that our search for the perfect people-and planet friendly option continues daily. “Water-based” and “waterborne” now are second only to “low-VOC” on the list of buzzwords that put our minds at ease. But when you consider that zero-VOC paints are readily available, the VOC content in floor coatings can seem high, in addition to other chemicals that some formulas use. This reality has made the ultra-violent curing machine the latest proven weapon in our arsenal of remedies for unhealthful indoor air. It stops chemical emissions by instantly curing the finish that would ordinarily take days to weeks to completely dry and stop off-gassing. In addition, waterborne polyurethanes with VOC content as low as 17 grams per liter are now available.

Custom design in cork gives light and warmth to dark kitchen Laura cork 2IMG_0037Laura wasn’t kidding when she said her new kitchen floor had to create a warmer, brighter space than the brown vinyl that once covered the floor in this room with very little natural light. Something natural that was indoor-air friendly would also be a plus, Laura thought as she began to research different floors.  Tile was her first choice. But the cement board  required as an underlayment would have raised the kitchen floor much higher than the adjoining rooms of carpet, hardwood and slate. She found a design – in cork flooring tiles – that she liked online, and selected colors for her own custom look. 

Managing flooring heights and ensuring floors contain no urea formaldehyde mean extra work on this job 012I made myself very clear on this project: All products would be proven to contain no added urea formaldehyde, and there would be no transitions. The homeowner had selected three styles of cork flooring that were almost ½-inch in thickness; prefinished solid hardwood that was ¾-inch; and the tile, the first flooring to go in, was sitting at 1-1/16th inches in height once installed. To complicate the job further, the cork was a floating floor, meaning that it does not get glued or nailed to the subfloor, which typically requires transitions, such as T-molding, where it meets up with other floors like tile and hardwood. So, we decided on a modified transition.

Air conditioning gets installed in the nick of time for proper moisture levels needed for hardwood and cork 003“The relative humidity is still reading 65 percent. Should we open or close the windows?” In preparing to install hardwood flooring, we have been monitoring moisture levels at this new construction site for weeks. It’s part of our normal preparation for installing hardwood and cork floors. “Don’t leave the windows open overnight or we’ll be sabotaged by night-time condensation,” our quality-control manager says. “The air conditioning is being installed tomorrow, and as long as that happens, we should be fine.” Tomorrow will be just 24 hours before all the flooring is delivered to acclimate in the home for three days prior to installation. The moisture content in the subfloors has been measured and was fine, but the relative humidity has been climbing since the walls were painted.
