Construction: innovating to reduce the energy cost of buildings
The construction industry is faced with ambitious sustainable development objectives. The Arkema group is present in the construction market and offers innovative and competitive solutions to improve the quality of construction materials and the energy performance of buildings.
Actions taken to fight global warming place great focus on the construction sector. Present in the construction market, the Arkema group provides sustainable solutions for the insulation of buildings and also for the manufacturing of materials which are more resistant and have a lower energy cost.
Thermal and sound insulation
Windows with better insulation
Windows are one of the main weak points of thermal insulation in buildings. The Arkema group has developed innovative solutions which contribute to the manufacturing of high performance, double-glazed windows.
Controlling solar radiation: when treated with Certincoat®, glass window surfaces limit the thermal exchange between the interior and exterior due to a better reflection of solar radiation. The temperature inside the building is more stable and energy costs are reduced by 30%.
Enhancing the efficiency of double-glazed windows: the Siliporite® molecular sieves are used in the aluminum frames placed between the two window panes in order to “capture” the condensation. This technology keeps the air in the double-glazing perfectly dry. As a result, insulation efficiency is increased, and the quality of the window is extended several years.
Optimizing the quality of PVC window profiles: Durastrength® and Clearstrength® additives respectively provide PVC profiles with impact resistance and UV resistance. These additives extend the quality of the frame structures. Plastistrength®, an acrylic process aid, enhances even the most rigid PVC formulation, which is used for the extrusion of the profiles.
For the thermal and sound insulation of walls, the Arkema group offers a whole range of solutions that meet the requirements of builders and sustainable construction certifications.
Forane® expansion agents for rigid polyurethane or polystyrene foam, the most widely used in the market. The new generation Forane® is based on hydrofluorolefins (HFOs) and has no impact on global warming.
Climatherm® from Bostik, a system for enhancing the thermal efficiency of buildings. Applied on external walls, this insulating solution is an effective way of enhancing buildings without reducing living areas.
Pebax® elastomer-based vapor-barrier films or membranes prevent the diffusion and stagnation of water vapor within the walls. Therefore they minimize damage to the materials as well as the appearance of sources harmful to health (mold).
Kynar Aquatec® PVDF resin-based coatings for reflective roofs customized for direct application on the job site. Roofs treated or coated with this product help minimize thermal exchanges (reflection of sun rays and limited absorption of heat by the roof). This results in lower energy consumption and longer service life for the roofs.
A new revolutionary sealant coating!
Bostik, the bonding solutions specialist, has developed the first thermal insulation levelling coating offering the same characteristics as a traditional levelling coating.
Enhanced with glass microbeads, this latest coating is used to insulate walls and ceilings by reducing heat loss (by up to 15% depending on wall thickness) and prevent damp and the sensation of a cold wall. Applied with a roller or a spatula, it ensures a perfectly smooth and ultra-white finish over a 2 mm thickness. Benefits include: time saving, reduction in wastes generated and in product consumption, minimum VOC emission (class A+), and lower energy costs.
Manufacturing of materials
Arkema develops additives to help lower both the cost and the environmental impact of materials.
Coatex, a subsidiary of the Arkema group, constantly innovates in order to develop higher performance materials, which are less costly and which consume less energy. Its range of Ethacryl™ dispersants and water-reducing agents for cement and plaster reduce the consumption of water and raw materials. As a result, energy costs and the carbon footprint for manufacturers are reduced.
To optimize the drying of concrete, Sartomer, another subsidiary of the Arkema group, produces specific acrylics for concrete additives.
Finally, Ceca, another Arkema group subsidiary, has developed a surfactant-based additive for asphalt mixes which is composed of 50% renewable raw materials. Small quantities are added to the bitumen/aggregate mix, thereby reducing the application temperature of the asphalt by about 50°C. Consequently, the amount of energy required to heat and spread the asphalt is reduced by 20 to 50% and dust emission by 90%. The result is that the impact on the environment is lessened and working conditions improved.
Cecabase® RT: the environmental impact of warm asphalt mix
Using Ceca surfactants for all European warm asphalt mix projects could represent an annual fuel savings of 700,000 tons, the equivalent of the annual heating needs of a town such as Marseille, France.
