SIXINCH USA’s goal is to reduce impacts to human and environment health by evaluation and control of chemicals of concern in our processes and facilities.

Comparing materials and chemicals found on the Red List we find that SIXINCH products meet the criteria for specification of Living Building Challenge buildings. The Living Building ChallengeSM 2.1 is a complex initiative and is not limited to compliance with a list of materials and chemicals, but clearly states the intent of environmental responsibility in product design and specification. For SIXINCH this is an on-going commitment and will involve continuous improvement.

We look forward to sharing more about our journey to even deeper sustainability. For more information visit our Environmental/Testing Information page.
