Research Type - Materials
| Name | Description | Research Items | 
|---|---|---|
| Bioproducts | Bioproducts are building materials derived from agricultural and forestry waste, and include corrosion- and flame-retardant coatings, low VOC insulating foams, and natural fiber-reinforced composites. | 16 | 
| Cement-Based | Cement-Based products are compositions that use cement to bind natural or manmade pre-cast building components. | 42 | 
| Ceramics | Ceramics are clay-based products that include bricks, blocks, and tiles for interior and exterior application. | 9 | 
| Composites | Composites are composed of at least two physically (not chemically) combined distinct building materials. They include matrixed materials, such as cement; fiber-reinforced plastics, such as fiberglass; and engineered wood products, such as plywood and oriented strand board. | 30 | 
| Fabrics | Fabrics, sometimes referred to as membranes, form the enclosure material for tensile structures composed of cables or supported by air pressure. | 6 | 
| Fluids | Fluids,/em> refer to the storage and conveyance components for liquids (including water and liquid fuels) and gases (such as natural gas) used within buildings. | 1 | 
| Foam | Foam products are those constructed of polystyrene or polyurethane foam, usually as an insulation material. | 15 | 
| Geomaterials | Geomaterials products are those that are derived from soil, rock, and concrete, and range from precast walls to gravel for roads. | 12 | 
| Glasses | Glasses traditionally are used for enclosure components, including windows, doors and some panels. This category encompasses sheet, reinforced, tempered, and heat-insulating glass, and glass products, such as glass bricks and tiles, and rolled glass sections. | 62 | 
| Metals and Alloys | Metals and Alloys include structural steel; steel, aluminum and copper roofing; and aluminum alloys for a variety of uses. | 33 | 
| Polymers | Polymers are products that have synthetic polymers as their base of composition and include linoleum, rubber linoleum, vinyl tiles, laminated paper plastics, glass-reinforced fiber plastics, chipboard, and some plastics. | 21 | 
| Wood | Wood products include timber, lumber, and composite products for structures, as well as interior and exterior finishings and fittings. | 39 |
