Additives Products with specific properties designed to modify the behavior of the materials they are added to. Adsorption Phenomenon whereby gas or liquid molecules bond to the solid surfaces of products with adsorbent properties, e.g. zeolites and activated carbon. Bioclimatic house House designed in relation to its environment, in particular with a heating and air-conditioning system making optimum use of solar radiation, thermal inertia of materials, and natural air circulation. Carbon footprint Calculation method used to compute greenhouse gas emissions, in particular carbon dioxide, related to a given activity. Dispersants Additives designed to maintain particles of product in suspension in a blend, in particular concrete. Fluorosurfactant a surfactant used to alter surface tension and solubilize two non-miscible phases, in particular within a polymerization reaction. HEQ initiative The « high environmental quality » initiative is an environmental concept applied to the design and renovation of buildings with the aim of minimizing their environmental impact as much as possible. Hydrofluorocarbons (HFCs) Substances containing hydrogen, carbon and fluorine, used as CFC (chlorofluorocarbon) substitutes. Hydrofluorolefins (HFOs) New fluorogases with very low global warming potential. Low energy consumption building French standard setting out energy requirements for heating, sanitary hot water, air-conditioning, lighting, and heating and ventilation auxiliary equipment in buildings. Polyurethanes Polymers used in particular in the form of expanded foam for their thermal and acoustic insulation properties. Vinylidene fluoride homopolymers (PVDF) Fluoropolymers marketed by Arkema under the tradename Kynar®, with outstanding resistance to weathering and chemicals, and many applications in particular in architecture and new energy sources, specifically photovoltaic power. |
