DSM, Büfa and NPSP Introduce a Sustainable Composites Construction for the Energy Neutral Enexis Building

11 June 2013

DSM, Büfa and NPSP Composieten have developed a new type of lightweight façade panel based on composite materials.

The façade elements, measuring 13m by 3m, have been used for constructing the new Enexis office building in Zwolle, Netherlands. The low panel weight resulted in a fast and easy installation. In addition, the specific shape of the panels contributes significantly to the low energy consumption of this energy-neutral building.

In collaboration with construction company BAM, more than 100 of these façade panels were installed on the new office. Because of their low weight and a specially developed and patented aligning anchor/ hook system, each panel can be mounted in only 5 minutes.

The panels were manufactured with a vacuum-infusion process based on DSM’s Synolite 1967 resin, Büfa’s Firestop 6815-N-3 resin/ S272-SV gelcoat, and a PUR foam core. The inherent design flexibility of composites enables manufacturing of components with unique shapes. The panels used for the Enexis building reflect sunlight because of their specific shape, and prevent heating up of the building in summer. Also, because of their excellent insulating properties they keep the heat inside in winter.

“The composite façade elements are of great help to direct the sunlight”, says Willem Böttger of NPSP Composieten. “I am very happy that we have been able to contribute to the BREEAM Excellent certification of this energy-neutral building.

“DSM is strongly promoting the use of composite materials in construction applications”, adds Ad de Koning, R&D Director of DSM Composite Resins. “For architects the design versatility of composites combined with their excellent inherent insulation performance makes them a very interesting alterative to steel and concrete.”
