The Super Spacer from Edgetech has played a role in the construction of the 5,500sqm glass façade of the Qatar National Library, which is home to more than a million books and 500,000 digital editions. 

The façade has been designed without any metallic elements, ensuring there are no thermal bridges to conduct heat into the building.

Its double-glazed IGUs are curved, ensuring that the façade is both self-supporting, and resistant to wind and other strong weather.

A low-e coating and a solar control coating filter and reflect sunlight, and a grey grid of 3mm metallic dots, with a 6mm spacing, was burnt into them to further reduce radiation transmission.

The need for both exceptional thermal performance and a product that was compatible with the building’s curved IGUs made Super Spacer TriSeal Flex an obvious choice, as Edgetech Managing Director Chris Alderson explained:

“In places like Qatar, the constant fluctuations between incredible heat in the day and much cooler evenings exerts considerable pressure on the edge seal. Super Spacer’s structural foam is able to absorb that pumping motion, allowing IGUs to withstand the pressure.

“This is one reason that Super Spacer has been specified in some of the world’s most iconic, architecturally ambitious buildings”
