Material Collection

Exterior & Structural

A facade and its underlying structure create the appearance and language of a building. Together with aesthetics, considerations of thermal performance, durability and maintenance are critical factors for these product choices.

Where energy efficiency in building product innovation has made great strides in the past decades, material choices have not always included consideration of Indoor Air Quality (IAQ) pollutants.

Avoiding commonly added toxic chemicals, such as halogenated flame retardants, high VOC emissions or toxic binders, allows exterior material choices to continue the goal of material health for people and planet.

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

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.

Purified Raw Linseed Oil

Linseed Oil is a natural, solvent-free finish coating derived from flax seeds. Not only does it perform better than petrochemical alternatives - it is also much healthier. Linseed oil is free of toxics such as isocyanates and bisphenols, which are found in polyurethane and epoxy resins. Allback manufactures their Purified Linseed Oil in Sweden. Their Purified Raw Linseed Oil is non-drying, it needs to be absorbed into the wood surface. It is ideal for reconstituting old linseed oil paint, storing paintbrushes after using linseed oil paint, and as a first coat on extremely dried out wood.

Aluminum Extruded Louver

Industrial Louvers, Inc. fabricates screens, vents and screens from extruded aluminum. Louvers and air vents allow air flow through openings in buildings while rejecting unwanted elements such as water and airborne debris. It is in coatings and finishes where hazardous substances need to be looked out for.
ILI’s standard finish is Valspar’s Fluropon® Pure which is declared and complies with Red List Free requirements for Living Building Challenge projects. The ingredient list shows a small percentage of Carbon Black which may cause irritation of the lungs in the manufacturing stage of its life cycle yet as it is not on the Red List it is LBC compliant.

Classico Limewash

Available At the Donghia Materials Library

Classico Limewash is a slaked-lime ( lime mixed with water) paint with which you can achieve wash off effects on interior or exterior brick and masonry. After application, it calcifies to the brick, turning hard as a rock. It does not chip or crack due to allowing moisture to evaporate. The high pH of the paint makes it naturally mold-resistant. As a result, maintenance is minimal. The application is done by brushing the paint on the wetted surface and creating the patina effect by hosing spots off the wall.

The products in this collection have all been evaluated holistically for their contents and performance. To be considered, a product must disclose at least 75% of its ingredients by weight and avoid the biggest health concerns, as indicated by their disclosure documentation.

For exterior products that means that they avoid halogenated flame retardants, solvents or toxic binders and are low-emitting with VOC requirements of 50 grams per liter for coatings, 100 g/l for primers and stains, and 50 g/l for tints. *BuildingGreen

Spec Guidance

Prefer coatings without PVA. Choose acrylic coatings with no polyvinyl acetate added.

Prefer solvent-free finishes. Use mineral silicate paints comprised of potassium silicate as they contain no solvents or VOCs and are resistant to UV and mold, mildew, and fungal growth. They require very little maintenance and have a long service life.

Avoid added biocides and antimicrobial additives. Biocides in stains and paints could potentially leach from the coating into surrounding water and soil

Avoid PolyFluorinated Chemicals. Choose Metal coatings that do not require highly fluorinated compounds (PFA/PFC) which may stay in natural surroundings for millennia

Avoid Hexavalent Chromium. It is used in vast industry processes such as coatings and applications. According to the EPA, Hexavalent Chromium (chromium VI) targets the lungs and depending on length of exposure, can be a carcinogen.
