The striped pattern characteristic of bamboo flooring is a byproduct of the production process. Many strips of bamboo are glued together, and then the strips are heated and compressed to set the glue and harden the bamboo. With that much glue involved, the switch to a formaldehyde-free binder is a significant upgrade for EcoTimber's solid materials.
It seems that only the solid styles of EcoTimber flooring are truly formaldehyde-free, as EcoTimber's website says the adhesive in their Woven Bamboo is "urea-formaldehyde free" and that the binder in their Engineered Bamboo is "virtually formaldehyde free."
Still, making a dependable, long-lasting adhesive without the use of formaldehyde is tricky and expensive, so we'll celebrate this as a big step forward for one of the most readily available brands of bamboo flooring.
Pricing will vary depending on your local green retailer's distance from EcoTimber's distribution center in Northern California.
