“Green” certifications that test chemical emissions don’t require compliance until long after the paint is dry
GREENGUARD®, Green Seal and SCS Indoor Advantage Gold. They’re all top third-party certifications designed to help us choose paint that will not make the air in our homes dangerous to breathe.
But while these labels mean chemical emissions have been measured -- or in the case of Green Seal dangerous ingredients have been prohibited -- none of them tells us what we are breathing at the time the paint is being applied. And certifications that test chemical emissions don’t require compliance with safety limits until 14 days after the paint is dry.
“When it comes to verifying sustainable claims, it may be wiser to start by being a ‘doubting Thomas’ instead of a ‘gullible Pollyanna’ …,” says Michael Mauch, AIA, LEED AP and principal of
RWA Architects in Cincinnati, OH. “Third-party verification is supposed to work like Politifact -- an organization to sort out the truth. But third-party verification is not a perfect system. In theory, it works, but in reality, there are many influences that can sway the outcome.”
There was a time not too long ago when we had to search to find “green” products and companies at the annual Greater Cincinnati Home & Garden Show.
But these days, you have to search hard to find exhibiting companies that don't have some claim to being “green.” Even when I was sure I had found one on opening day, I was wrong.
There is nothing, I was sure, of environmental note about the slot machines on display by Gambler's Oasis. But then I learned that this business buys machines that are about to be discarded, refurbishes them, and sells them for use in home game rooms.
Q. I want to put carpet that has low chemical emissions in my basement. I also had planned on using a natural fiber carpet pad. I have not ever had water leak into the basement, but there is some moisture, due simply to the fact that it is a room below ground level.
Do natural fiber carpet pads hold up to moisture and would it be better to use a sheet of plastic as a vapor barrier under the carpet pad?
A. Installing carpet in the basement you describe requires a moisture- and mildew-resistant carpet pad, which will be glued in some spots to the basement’s cement floor. Putting a vapor barrier under the carpet pad would allow the pad to move and bunch up in spots under your carpet, which is not desirable.
If the basement does not leak, my usual recommendation would be a ½-inch rebond or rubber pad that is water-resistant and treated with an antimicrobial agent to prevent mold and mildew. If you were looking to install laminate or any hard surface floating floor, a vapor barrier would be needed.
