Swisspacer integral to Heldentoren landmark

Swisspacer Ultimate warm edge spacer bar features in a prominent architectural landmark on the beach promenade of popular Belgian seaside resort, Knokke-Heist.

The Heldentoren, with its two sister buildings, offers its residents panoramic sea views and consists of a residential tower with 43 apartments, a second seven-storey building with 10 apartments and a smaller pavilion that houses a restaurant and an additional apartment on the upper floor.

On the second façade level behind narrow bands of ceramic panels and glass balustrades, the façades are almost completely glazed. Slim aluminium frames, finished in deep midnight blue, hold the window and door openings, which feature a combination of sliding, hinged and fixed glazing elements.

Double or triple-glazed insulating glass units protect the partly two-storey apartments from wind and solar heat, reflect UV rays, and at the same time offer high light transmission, allowing natural daylight to penetrate deep into the living spaces.

In terms of both performance and appearance, glass manufacturer Polypane chose the Swisspacer Ultimate warm edge spacer for the insulating glazing. “The requirements for the thermal conductivity of the insulating glazing were high,” said Franky Symoens, CEO of Polypane.

“Triple glazing with a Ug value of 0.6 W/(m²K) and double glazing with a Ug value of 1.0 W/(m²K) were used as well as Swisspacer Ultimate for the glass edge. This spacer bar enables particularly low Psi values and thus supports the energy efficiency of the overall system.

“Swisspacer Ultimate is one of the world’s leading warm edge spacer bars. It minimises heat loss at the edge of the glass and has been proven to improve the energy efficiency of windows and façades. This reduces CO₂ emissions and has a positive impact on the building’s overall carbon footprint. With its matte surface, it blends seamlessly into any design concept.”
