In a Home, Every Product Matters
Homes are constructed with hundreds of different materials, most of which contain chemicals. Knowing what those chemicals are and which products are least toxic has proven to be a challenging task. This list is the result of over 2,000 hours of research by the Hayward Lumber and Hayward Healthy Home Institute staff reviewing product use and performance, MSDS, and interviews with manufacturers, chemists, and other experts. Our goal was to find products that are both high-performance and non-toxic so you can build healthy homes.
The list includes products in a wide variety of categories. Each product is given a designation:
- Permitted: Product may be used as-is.
- Permitted, with conditions: Product may be used, but contains solvents or toxins that require management during preparation, installation, and/or finishing.
- Permitted, with strict conditions: Product would not be permitted, but no alternative exists and/or code requires it to be used.
- Not Permitted: Product contains solvents or toxins that present undue health risks and/or are on The Red List.
About the Evaluated Products List:
This list is not exhaustive and will be updated regularly. Currently, it only includes products (and in some cases product categories) that were considered for use in the first Hayward Healthy Home. We continue to do research and will update the list quarterly. Please note the expiration date printed on the top of the list, so you are sure you are using the most updated version.
- Some products could not be fully analyzed. In our research we found many MSDS were out of date and in some cases manufacturing process had changed or moved offshore where controls on chemical use are less stringent. We followed up directly with manufacturers but found many either were not forthcoming about chemicals contained in their products or simply did not know the source of chemicals coming from 3rd parties.
- Rationale and product notes have been provided to explain the reasons for the rating and conditions under which products can be used. These are meant to provide some basic information, not detailed installation instructions.
- Everybody is different. Chemical sensitivities vary person to person. Even people from the same family, living in the same house, can have different reactions to chemicals and materials, alone or in combination. While this list provides and excellent starting point, it is not a substitute for testing your own personal compatibility with the building materials used in your home. We recommend building a chemical sample board to determine reactions to individual chemicals or chemical combinations.
- We have incorporated the Red List. This is the most well known “do not use” list developed by the Living Future Institute.
We have placed our work into the public domain to support cost-effective healthy home construction. Help us build the list by commenting on products you have found to be both high performance and non-toxic or on products already included on our list. Contact Us
