TriSeal™ Premium Plus spearheads Paris sustainability revolution

TriSeal™ Premium Plus spearheads Paris sustainability revolution

For hundreds of years, the town of Saint-Denis played an integral part in French history – both as the historic resting place of generations of the country’s Royals, and the birthplace of Gothic architecture. 


But today, it’s home to pioneering buildings of a very different kind. A suburb of Paris since the 1960s, it’s now at the forefront of the French capital’s sustainability revolution. 


In 2024, Saint-Denis will be the site of the athlete’s village at the Paris Olympics, which is being built to stringent sustainability standards (all buildings under eight storeys must be made of wood). And nearby, you’ll find the 30-hectare ZAC de la Montjoie eco-district – which is home to a spectacular new building only made possible with Edgetech innovation. 


The Curve is a 24,400 square-metre, seven-storey office complex that accommodates over a thousand businesses, restaurants, fitness centres and more. 


The building’s sustainably-sourced wooden structure consists of 5,000 cubic metres of laminated timber, while its 10,000 square-metre glass façade has been designed to flood the interior with natural light, and therefore reduce the need for electric lighting. 


Especially innovative and challenging to execute were the building’s rounded glass corners, which were made of concavely and convexly-curved units, consisting of Saint-Gobain solar control glass, and, crucially, Edgetech’s Super Spacer® TriSeal™ Premium Plus. 


TriSeal is a triple-seal system designed to meet the most stringent commercial requirements. 


With a thermal conductivity of just 0.15 W/mk, excellent condensation resistance, shape retention and colour stability, and outstanding longevity, TriSeal was the perfect choice for this state-of-the-art sustainable architecture. 


“Architects around the world are at the forefront of efforts to make our built environments as sustainable as they can possibly be,” comments Edgetech Managing Director Chris Alderson. 


“We’re delighted to be playing a part in bringing so many boundary-breaking green buildings to life – and are confident that Super Spacer® TriSeal™ Premium Plus will ensure the Curve’s thousands of glass units will continue performing to the highest standards for many years to come.”
