Material Collection

Wall Coverings

Wall surfaces make up a large portion of a room. So we are particularly interested in reducing exposure to toxics in these materials.
To meet code requirements, interior wall coverings such as wallpapers or interior wall cladding like wood paneling and cork boards can contain substances that can harm human health. Additives used to resist mildew, stains, and fire include PFAS, flame retardants, and antimicrobial chemicals. Wallpapers made with vinyl should be avoided for their hazardous impact throughout their entire lifecycle. Choosing a Healthier Finish options on wood panels can help prevent exposure to toxics in high-touch areas.
Below are a few examples of wall surfaces that meet our rigorous evaluation.

About Our Collections

The goal of our collections is to help promote transparency in the material ingredients of building products by fostering knowledge and awareness of products and materials for which life-cycle information is available, and that have environmentally, economically, and socially preferable life-cycle impacts.

Keep an eye out for the following symbols:
A Healthier Affordable Building Product

Products with the designation of "Healthier & Affordable" were specified and installed in at least one of our Case Studies of healthier affordable housing.

Available at the Donghia healthier Materials Library

The Donghia healthier Materials Library library is open to Parsons student and faculty. Learn more about access and opening hours here.

Low Embodied Carbon

“Embodied Carbon” is the total amount of carbon emitted during the process of making a material. *HML refers to a manufacturer's EPD to determine whether a product's A1-A3 carbon emissions falls within HML's threshold for Low Embodied Carbon.

New Product

This product has been added to the collection within the past six months.

Product in Development

Products with this designation identify they are currently scaling or only available in markets outside of the building industry. they could be experimental or in use in capsule collections.

Available in the EU

Products with this designation are currently available only in the European Union and identified as being an exemplary healthy option in the respective product group.

Ingredient Disclosures

There are several ways of evaluating a material’s health that we include with product information. Disclosures are reports by manufacturers about product ingredients, impacts, or other attributes.

Key Disclosures include:
Health Product Declaration (HPD)

A voluntary technical specification for reporting information on product contents and associated health information, intended to be the health-analogue to Environmental Product Declarations (EPDs).

Declare Label

Declare is a transparency platform and product database that answers three questions:
1. Where does a product come from?
2. What is it made of?
3. Where does it go at the end of its life?

Environmental Product Declaration (EPD)

A standardized format for communicating the environmental effects associated with a product’s raw materials extraction, energy use, chemical makeup, waste generation, and emissions to air, soil, and water.

Safety Data Sheet (SDS)

A reporting format that provides basic information about a material’s chemical ingredients, the potential safety hazards to installers, and recommended practices for installation.

USDA Certified Biobased Product Label

Managed by the U.S. Department of Agriculture (USDA), the goal of the BioPreferred Program is to increase the purchase and use of biobased products.

Thermowood

Low-Embodied Carbon Material

Lunawood Thermowood avoids chemicals in its manufacturing processes, relying solely on a treatment with high heat and steam that enhances the wood's durability. This allows for an extended lifetime and a surface that requires no finishing and less routine maintenance, regardless of climate. However, applying paints, oils, and other finishes is possible (please see HML's list of healthier finishes for recommendations). Since the processing eliminates natural resins, no resin will secrete through any applied finish or paint.

Per EPD, this product meets HML's criteria for low embodied carbon.

The products in this collection have been evaluated holistically for their contents and performance. To be considered, a product must disclose at least 75% of its ingredients by weight. It should avoid the biggest health concerns (such as those indicated in the HML Spec guidance for this product category) or be third-party certified. For wall surfaces, this means that they avoid hazardous flame retardants, antimicrobials, stain repellents made with PFAS, and vinyl (PVC).

Spec Guidance

Avoid Vinyl Products - Type II wallcovering (heavy duty, high traffic areas) are often made of vinyl or vinyl blends. Backings often also contain PVC or other harmful plastics. Look for products that are made of natural materials like flax, cellulose, or bioplastics awarded the USDA Certified Biobased Product Label in the BioPreferred® Program. For the backing, look for products that have FSC-certified paper, flax, or other natural material backings.

Avoid stain and water repellents containing PFAS.

Avoid added flame retardants if possible. Sometimes they are required to meet code. Be sure to double-check the code specific to your project.

Check to make sure adhesives are low to no VOC. Peel and stick come with adhesives on the back of paper. For traditional paper you paste yourself, check for natural options such as rice or wheat paste. Consider options from our Collection for Adhesives, Mortars Grouts and Sealants

Check whether a copper additive could be an option to fulfill antimicrobial performances

Look for inks that are GreenGuard or Nordic Swan certified if possible

Opt for cladding made from natural materials such as cork, FSC certified or reclaimed wood or FSC certified cellulose based wallpaper

Opt for stenciling or a wash with mineral based paint

Opt for tile or natural coverings that are inherently durable
